Muffler of Choice?

[Zed]

I have a great opportunity through my current insurance claim to choose any muffler (slip on) I want within NZ$1000 price range. So based on price and availability I am considering titanium Micron, Arrow, and Scorpion cans (in that order). I would prefer a Yoshimura but have been told that the wait is 12+ weeks <_<

If anyone owns or has owned any of these brands I would be most interested in your opinion? Thanks. :)

I love my Micron can on my '97 CBR600. Sounds great & seems to be good build quality.

[wkid_one]

I had both the Microns and the Scorpians - prefer the sound of the Microns in all honesty on a multi.

[James Deuce]

I've got a Neptune on my CBR and it sounds wonderful.

[Zed]

I've got a Neptune on my CBR and it sounds wonderful.Hmmm...they look alright and their website claims they are no worse in performance than other reputable brands. NZ made is a good thing, but they don't come in Titanium.

Jim, any idea on an approx. price? I have emailed them for a P&A.

[Yamahamaman]

I giving a lot of consideration to a oval Staintune as a birthday gift to myself in August.

Aussie mufflers!!!

Probably wouldn't get one myself because they look identical to the OEM one that I am removing...not that looks are too important. :msn-wink:

[Grumpy]

I have fitted a set of Scorpion Titanium mufflers to my 1400 and am pretty happy with the sound and finish as long as you peel that horrible stuck on logo off. It's bound to lift of as the pipe gets older anyway and then you are left with a hard blob of adehsive. Get it off before you run them.
As happy as I am with the pipes my first choice would be the Micron Titanium.

[Racey Rider]

Could they make that Arrow can any longer!?

Looks like a mortar firing tube.
Might keep the cops at bay. :D

But then, you may like the James bond - mortar firing look

So they use a sticker and not a metal badge like most others?? Mustn't have had enuf complaints to warrant abolishing the sticker?

I've seen a few that had started to peel off but in saying that, I've seen a few that were as good as gold. I didn't want to take any chances so off mine came. Besides that I think they look quite good minus the decal. Nice clean finish.

$449 for the muffler, and $50 for the connector pipe. Mine is in brushed Stainless and an oval. I can confirm that the top end was markedly improved, and there was a little mid-range dip that went away.

Mark is also a top bloke and dropped me off and picked me up to/from work when he did the job. Obviously not an option in Auckland, but it goes to show what sort of business he runs.

I was in red baron last week and saw the XV1700. Now if the Arrow is a mortar then the standard muffler on the road warrior is a howitzer. The sales guy called it the hot water cylinder.

[dangerous]

I have Scorpions on the Storm (and I like my colour matched badge, still well stuck on :bleh: ) With the V2 the sound is more high pitched sounds more 2 into 1 sounding I would prefure a lower note so I dont know how they would sound on a 4cyl.
The biuld quality is bloody good as is the finish but still the other brands you mention are a more popular brand tis up ta you Z.

ps: Grump's those titanium's look 'sweet' :second: <--- cos the badge is missing other wise it would of been a 1

[Hitcher]

The Zrex gets a Neptune next week. I hope that it sounds as good as the Kerker. Even a longer wait on these than the Scorpions, Zed...

[fastford111]

i have a yoshi on my rsv1000 it sounds sweet nice and deep it was 600 notes dont like the end caps on micron cans they stick out to much

[James Deuce]

And if it doesn't sound as good tell Mark and he'll change.

You should just tell him you want it to sound like the Kerker.

[Hoon]

Micron titanium race oval can gets my vote!!

As happy as I am with the pipes my first choice would be the Micron Titanium.
Your Scorpions are a nice look...the titanium blue fits in nicely with your paintjob! I'm after a similar look, and Micron does some in red as per the pic I posted.

Thanks Jim, I actually just received the following email from him:

Hi Mathew,
Thanks for your inquiry.
We would need your original muffler sent down to us to measure up.
We would pay the courier costs both ways.
The cost of the oval polished or brushed stainless double outlet muffler is $765.00 inc gst & link pipe.
We could have it completed in 7-10 days.
The titanium mufflers are under development but a few months off yet.
You will get in power through mid range & a nice deep throaty sound.

Best regards

Yeah - I like the Microns as said before.

Would go Akropovic if money was no object.

Ideally you would want the Micron Pipes with the Serpent pipes - wicked believe me!

Micron do all these colours

I had the large centre one on the R1.

Had alloy Two Bros on the VTR, shit quality, and worst of all, they needed constant buffing/polishing as they dull hell quick. Then went to the Stainless Scorpians - which had nice quality and sound (stickers peel off tho).

Here are some 600F's with Microns on

Hi Zed.

I had a Neptune on my R1150R, have them on my 800 and will be getting them fitted to my 1000 shortly.

I agree with Jim, Mark is a top bloke with a great product.

I like the way you can choose your style, and they have a metal badge, not a sticker.

Zed What about a Two brothers racing pipe. Developed specially for Hondas and amazing build quality. I have a Titanium one on the Gixxer and it sounds hot!

It also smothed out the tingly vibration through the midrange and gave it some in the bottom end.

You'd be suprised at the price too!

[vifferman]

Zed What about a Two brothers racing pipe. Developed specially for Hondas and amazing build quality. Amazing build quality?!?
Must be a different Two Bros from all the ones I've ever come across then. Most are loud, and not well built. From what I've read on other forums, Two Bros (actually "One Bro" since one left to start Erion Racing, who also make systems) spend little if anything on R&D and it's just guesswork and copying other systems.

[White trash]

Ummm.....? Really?

I've seen the R&D they put into their bits and pieces and was impressed.

How much research you think goes into a Neptune? Not bagging them or anything coz they're inexpensive. Just not what I'd call a performance muffler.

[vifferman]

Ummm.....? Really?Yeah. F'rinstance - my VTR originally had 2-Bros, but a previous owner removed them as he said they were much louder and gave less power on the dyno than standard pipes with a bafflectomy. Similarly, they are not highly rated on various VFR lists, the CF ones fall apart fairly readily, and the US VFR listers said their customer service was crap and that they were arrogant assholes.
To be fair, my only personal experience was that on bikes I've ridden with them on, they were too loud and looked cobbled together. They are popular in that they are cheap and were included as a 'free' extra on the VTRs for a while.

I've seen the R&D they put into their bits and pieces and was impressed.How do you 'see' R&D? (No, I'm not having a go at you, WT).

How much research you think goes into a Neptune? Not bagging them or anything coz they're inexpensive. Just not what I'd call a performance muffler.Fair comment, and you could say the same about many manufacturers. If I was buying a Neptune, it'd be for looks and sound, and customer service.
If you were interested in seeing a real performance improvement from a muffler/system, then it'd pay to do some research first into which companies actually dyno their pipes, assuming the data is reliable.

The bike manufacturers actually do a pretty good job on their pipes anyway, which you'd expect because they're matching the zorsts to the engine setup. So you're only going to see maybe a couple of HP at the top end (which is only vald for racing - who rides at max revs all the time on the road?) and maybe a slight gain in the midrange (important), where a lot of bikes experience a slight dip due to the setup for emissions/noise testing in Europe and California. However, this usually requires some retuning and/or rejetting, and REAL gains are only going to be had with a full replacement (read: race)system anyway. Most gains are usually at the expense of low to mid-range anyway, aren't they? On the 'Storm, no real power gains are to be had until you fit high-comp pistons and more radical cams, so fitting other zorsts is done for looks and sound.

To be honest, I reckon most people would buy an aftermarket pipe or muffler for the pose factor and sound anyway, as the OEM ones are (a) usually too emasculated, (b) too heavy and (c) not very attractive.

ZedThanks for all the feedback peoples - I have decided to go with a stainless Scorpion pipe, a k&n filter, and a dynojet carb kit. This will all be covered under the cost of a new OEM Honda muffler! Lou, thanks for your assistance. I told Spectrum to get the filter & carb kit from you.

From their website:
Dyno Tested
Scorpion obtains new motorcycle models from our network of dealers as soon as they become available. Then it's straight into the Dyno room where we test the bike with the O.E.M. exhaust still fitted to see where improvements can be made - not just in power and torque, but also ground clearence, ease of fitment and looks.
Each Scorpion exhaust is specifically designed for the particular application. Scorpion exhausts are designed to boost power, not just at peak revs, but through the RPM range, giving you greater throttle response and improved overall performance - especially in the mid-range.
We run computer simulated acceleration tests so we can see how much faster the bike will be travelling over a timed burst of throttle. A scorpion equipped CBR900RR, in just 7.40 seconds, travelled 6 mph faster and covered and extra 39 feet!
Impressive we think you'll agree!

Will post a pic of the bike on its completion. :soon:


Zed

[Coldkiwi]

ahh, buy a yoshi or akra pipe and be done with it man! best flippin systems around, just ask the race teams. 12 week wait on the yoshi is pretty substandard though. you should be able to get an akrapovic for $1000 tho.

In the same way that I wouldn't call Wellington Motorcycles a Performance Motorcycle retailer?

Because that would be a serious bagging.

Unless all these systems were tested using the same dyno, wouldn't that 4 - 5 HP difference be about the margin of error between different dynos, different bike, different operators, different temperature/humidity/altitude, etc. Was your increase verified with a before and after dyno run?

My 800 is quoted at 73hp standard. When I had my Neptunes fitted it was dynoed at 84.1. I didn't have it dynoed standard on the same dyno, so there could well be margin for error, but I'm pretty happy with the result, and I can definitely feel that it breathes easier - plus it sounds and looks great. the sound is the main reason I get aftermarket pipes.

This will be the 1st aftermarket pipe I've purchased, in fact every bike I've owned (7) has had a standard pipe on. So, the main reason I get aftermarket pipes is because in this case I can! I'm looking forward to the change in looks, sound, and performance, especially with a filter & carb kit added. Then I'll be able to come back and give a more personal reason why I would buy one.

Hey - just a thought; are you committed to the K&N and Dynojet kit? The reason I ask is that there are other options out there, and for some bikes (like the VTR) the K&N is the worst option for an airfilter, as is the Dynojet ket. Have you done some Interweb research on fettling CBRs with these?

'Everyone' seems to go for the K&N hype, but it's not always all good. Most VTR owners who've fitted K&Ns have found that it mucks up the good job Honda did with blueprinting the VTR airbox (it has a baffle to tune the airflow, which the K&N doesn't), and it runs so lean that jetting is a mission, even using specs others have used. Also, Dynojet quality isn't always good: their needles aren't as well machined as stock, and you have to drill the carb slides. Factory Titanium jets are generally preferred for the VTR. I've read many posts of guys who've K&Ned their VTRs and can't get them running OK, and the usual response is "Take it out, put the stocker back in, and fit some Factory jets." Even those who do successfully install the K&N don't reap any significant horsepower gains, despite spending much time and money getting the jetting right.

My VTR is supposedly Dynojetted, and apart from a lean surge(?) on constant throttle, it runs well. However, I have doubts as to whether it really has been jetted, as the needles look like the stock ones (albeit now shimmed by me). I'm running a Unifilter (custom made), as this worked well on my VFR, and is much cheaper than either stock or K&N, didn't make a huge difference to jetting, and is rewashable.

Have you done some Interweb research on fettling CBRs with these? There is debate on whether certain mods gain extra performance or just make things worse. It seems that there are more positive than negative comments made by the CBR owners I have read, so I'll take the plunge and if I discover no/worse results then I'll just reverse the work done. Good opportunity to accelerate my technical knowledge on the subject. I am a bit of a novice in this area and advice from those "in the know" I do value, thanks.

Regarding the airfilter - again the best thing you can do is strip the stock filter back to the frame and replace the standard filter with a foam replacement (K&N foam is fine) and put it back in.

Did it with mine - worked a treat. Then put a 8mm spacer in the rear, race tech front end internals with gold valves and the bike bike handles much better to match the (slight) performance increase~

I agree with FS tho - given you are doing the whole intake and exhaust - you will need to spend some money on some decent dyno time to make sure you make the most of the money you have spent on the bits - as you will need to remap the engine to suit the new breathing characteristics of the bike - otherwise making the changes can be more detrimental than advantageous.

Remember the manu did R&D on the bike based on the way it comes out of the factory - putting new pipes and intake system on the bike without doing the remapping is pointless - no different than cars.

Shit -brings me back to what a bitch remapping the VR4 was when I did that up. They also have an Airflow Meter tucked in behind the filter which can make things extremely bloody tricky!

Zed - one question to ask yourself is: Is it worth getting the jet/filter and pipe kit - or do you just replace the pipe and offset the difference against your excess - as in all honestly - you are hardly going to notice the extra 2-3hp the filter and jet kit will give you

Appreciate your thoughts. I'm still going with the can, filter, and carb kit...will let you know the results once done. :soon:

Mate - best option with the VTR is to get the next size up in jets - which stops any detonation & pinging (VTR's tend to run a tad lean)....wouldn't bother with titanium jets - no real value.

Regarding the airfilter - again the best thing you can do is strip the stock filter back to the frame and replace the standard filter with a foam replacement (K&N foam is fine) and put it back in.Wkid - you need to learn to read more betterer!:Pokey:
My VTR has a custom Unifilter - I stripped the stock filter back to the frame and replaced the standard filter with a foam replacement (Unifilter foam is fine) and put it back in. Also, the TPS has been adjusted to 430 ohms at idle, as per recommendations (not the 630 it came with). I think the lean surge / misfire at idle is either crap in the carbs (found a lot on the filter) or it's slightly lean on the front carb (fixable by a shim or two under the needle).

Yeah sorry I am not pyshic to read between the lines and understand 'custom' means stripped back to the frame and replaced with after market foam - my bad!!
Try being more explicit next time yeah?

I went up the next size in jets and killed most of my problems with stutter and mis-firing at mixed throttles, did use a tad more gas tho - which on a VTR is not a great thing.....went to dual spark colder plugs too - which seemed to help.

Good on you Zed.....hope it is money well spent.

No doubt I will see you on the road/track in Auckland next time I am up to the track towards the end of the year.

Unless all these systems were tested using the same dyno, wouldn't that 4 - 5 HP difference be about the margin of error between different dynos, different bike, different operators, different temperature/humidity/altitude, etc. Was your increase verified with a before and after dyno run?

In my case they were done on the exact same dyno, 110.0 before and 120.1 after. No other mods were made.

Brent put the pipe on today. I'm going in to collect my old pipe on Sat and will start the bike up to see how it sounds...varooooooooom! Will post a pic then of the new look scorpion.

Heard of a Wileyco exhaust? Bought a carbon slip on for my 97 CBR600 off ebay. Bit loud but seems well enough made, built in Italy.

Came in box with bracket, pipe to main collector box, tee shirt. cap and stickers etc about $180US + $30 US air freight, arrived within a week.

Doesn't seem to have unscrewed, but it was never tight to begin with and the O-ring I put under its head was a bit crap. Time for a judicious application of Silastic, methinks...


Good on you Zed.....hope it is money well spent.Yeah - hope you really enjoy it, Zed. :)

Hi gav, nice website that! How has the condition of your carbon can lasted? I have been told that the finish on carbon mufflers deteriorates quickly. :disapint:

I have the Yoshis on the SV and like the look and the sound, BMC air filter also. :2thumbsup

Nice shot...I think Yoshimuras look good on anything! :cool:

Did you notice any changes in performance with the pipes & filter, or did they come with it when you bought it?

Thanks for all the feedback peoples - I have decided to go with a stainless Scorpion pipe, a k&n filter, and a dynojet carb kit. This will all be covered under the cost of a new OEM Honda muffler! Lou, thanks for your assistance. I told Spectrum to get the filter & carb kit from you.

From their website:
Dyno Tested
Scorpion obtains new motorcycle models from our network of dealers as soon as they become available. Then it's straight into the Dyno room where we test the bike with the O.E.M. exhaust still fitted to see where improvements can be made - not just in power and torque, but also ground clearence, ease of fitment and looks.
Each Scorpion exhaust is specifically designed for the particular application. Scorpion exhausts are designed to boost power, not just at peak revs, but through the RPM range, giving you greater throttle response and improved overall performance - especially in the mid-range.
We run computer simulated acceleration tests so we can see how much faster the bike will be travelling over a timed burst of throttle. A scorpion equipped CBR900RR, in just 7.40 seconds, travelled 6 mph faster and covered and extra 39 feet!
Impressive we think you'll agree!

Will post a pic of the bike on its completion. :soon:


ZedI went to the bike shop to collect my old pipe this morning and just couldn't resist cranking the bike over to hear what it sounds like with the new scorpion fitted - it's a totally new throaty growl! Hope it's not too loud as to wake up my new nieghbours? :rolleyes:

Looks fabulous!!

I'm glad there was an upside to your off.

[aza131]

There was a slight boost in the midrange power, but it was worth the cost just for the sound. It had the originall pipes on when i bought it new but changed them after about 4 weeks, it sounded like a sewing machine before!

[Zed]

Can't wait to see the pictures. Excellent that Lou was able to help out too.
Pics of the finished product as promised. Looks brand new again!

It looks better than new!

Have you been for a decent ride yet?

Yes Jim, went for a 4 hour ride yesterday with Firefight & 5 other KBr's. It rode like a dream...I think there is an increase in power too because the front kept on coming up, even in 2nd gear!! :whistle: Sounds and feels nice with the new scorpion fitted - would now most definately recommend to anyone with a sportsbike to get an aftermarket can!

Thats right, I forgot that in my write up, there were a few good monos from you Zed, nicely done :niceone:

Hey, looking good Zed..... just like mine :rolleyes: Are those after market indercators on the rear? I just put some clear lenses on the VTR I had to get em from Oz as there are no such things in NZ, according to my Honda dealer.

I helped a mate put some Neptunes on his Bussa last w/e they look and sound bloody nice (deap rumble) but could be louder and the end caps point outwards which dont like but the owner doesent mind.

Yes, I got two pairs from America. I only put them on the rear though cos they look stupid on the front...will be getting some clear lenses & amber bulbs for the oem front indicators in time.

They look the part! I'd be happy if I owned it :rolleyes:

All good safe fun F/F...but nothing in comparison to the full length standing monos the guy on the Gixxer was pulling down the front straight at Puke :not: when we arrived there to watch after our ride back from Ngaruawahia.

Very VERY nice Zed.

I'm drooling with envy. :niceone:

Bollocks, Street & Sport Motorcycles have some of those clear indicators, I bought some for my CBR600F, they are so small you can hardly see them, but are pretty bright.

My model has a plastic inner liner that screws inside the fairing, the oem indicator bolts to this panel and the mini indicators do the same :niceone: way too easy, scary in fact.

Na mate, the ones that I wanted/have are a lense replacment only as I wanted to retain the oem look.

You guys need to remember that my VTR is a series 2 which has way smaller indercators than the early CBR, VTR's do. so in IMO they look the mutts nutts.

$35au
