Aftermarket can advice......recommendations please

[Boob Johnson]

Hey dudes n dudettes. Finally replaced my written off bike on Wednesday & im well keen to sex this RF900 up :Punk:


Im not bothered about increasing power/torque it has way more than enough for me, but hey if it does then that's all good by me too. My reasoning is im after a deep, throatie rumble. Basically wanting it to sound as grunty as possible.

Was at a bike shop today & the salesman showed me his Kwaka 900 with an after market exhaust & while it did sound better than standard still wasn't THAT good I thought. I've heard some wicked bikes before & wishing mine to sound the same :sunny:


So yeah can all you after market Can owners can you recommend me the best sounding one that fits an RF900.


ps: ill be keeping the stock one in the garage for warrant day :Police: <_<

[Sanx]

In my extremely limited experience, Micron and Scorpion cans generally have a good sound to them. I have no idea about fitment for the RF900, but I'm sure somethings available.

[imdying]

You can generally perform a mufflerectomy on the standard one if you're careful. And by careful, I mean don't make it so obnoxiously loud that you can't pass a warrant :no:

[Katman]

Try a Neptune muffler. New Zealand made - looks and sounds great.

[MSTRS]

The can is only one part of the total exhaust system. To get the best sound and performance, you need to achieve an unrestricted flow with no choke points, no sharp bends, no baffle plates inside the can, headers of equal length, and at each stage of two or more pipes 'coming together' the next section of pipe must be large enough that it's capacity is the same as the pipes preceding it. To get totally scientific, you are trying to achieve a 'tuned' system, which will also require that each section be of a particular diameter and length, the idea being that sound waves travel in harmony.

[imdying]

headers of equal lengthThe 999 and the Vyrus (the 999 powered one) doesn't have that :blip:

The Vyrus is quite unusual... exhaust tuners have know for a while that they don't need to be the same length, just 'tuned' the same through bends/pipe sizing/other cool stuff that's over my head. The Vyrus has a 700mm rear header pipe, and the front is about 1.5-2m (both approximate iirc values, pretty sure the rear is about 700mm, but you get the idea as far as relative values go :yes:).

Over mine too...point is tho, I guess equal volume = equal length/size. Easier to have equal length headers if possible. I know that V-twins pose difficulties in this regard, but in-line fours generally do not.
In Boob's case, the 'right' can is probably all that is reqd, there are heaps to choose from, but one will stand out as most suitable for an RF900. I don't know which one tho.
EDIT: Be aware that if you achieve a free-enough-flow, it may be necessary to re-jet the carbies since the engine will run too lean at higher revs

[imdying]

Check the various website forums (fora?) that deal with your model bike.
Usually these will give good information.

I don't mean rush in and ask, you will almost certainly upset their version of the "Re-post Police". Just read the previous posts and check the information they have in the "Files" section. A look at the photos in their "Gallery" should also give an indication as to what's hot and what's not...

Of course the "Arrow" importer is in your town, although a fat lot of good that will do you :-) Don doesn't do retail, and he doesn't do discounts :nono:

[Boob Johnson]

Thanks for the replies guys. Yeah saw that Suzi & Yoshi are tight just im a lil Jewish (well almost I just haven't saved enough yet :shutup:) I just can't justify that sort of money on a small hunk of metal :oi-grr:


Saw this one -----> http://www.trademe.co.nz/Browse/Listing.aspx?id=111137383


The chap (with terribly broken english) seems to think it will do the job?


Seems like unless I can find someone here or at a bike shop that can confirm what im after exactly im gunna be taking a stab n the dark

[imdying]

A muffler is essentially a 2-1/4" baffle tube with some packing around it, it takes a bit of effort to design a 'crap' one (that is Microns opinion, might be worth poking around their site to see the context in which they make that statement).

[MSTRS]

Full stainless will look much nicer and have a longer life, but more $$.

[Boob Johnson]

Full stainless will look much nicer and have a longer life, but more $$.Yeah I love the look of polished stainless. The one in the TM linky is only $220 :love:

[MSTRS]

* Brand new oval stainless steel muffler!


* Universal muffler ,basically can fit all the bike with side mount muffler.


* alloy sleve with stainless steel endcaps and internals

I'm confused....

[kinger]

As an add on, I'll ask the main question in a minute.
I've done a mufflerectomy on the standard cans for my XJR, and it does what you're after. It's a deeper, throatier rumble, and passed VIN and WoF no problem. Just make sure you use stainless rivets to reassemble.
Now, my main question. How are race cans viewed if pulled. Bearing in mind the noise that Imprezas, Evos and Harleys make, is my popping on the overrun and quite fruity pair of Laser race cans going to get my collar felt?
The bike's got an aftermarket collector box as well, and is jetted for the race cans.

[MSTRS]

Check this thread http://www.kiwibiker.co.nz/forums/showthread.php?t=54001 .
Lots of good info there if you dig deep

[kinger]

A good debate, generally everyone thinks the law is an ass.
So, it's Yam's off, Lasers on til WoF time....:done:

[babyblade250rr]

theres a place in east tamaki called custom chambers they do stainless mufflers my wanna contact them

[kinger]

An afterthought.
Can anyone tell me the official wording on these riveted plates?
My race cans have a lovely welded bracket rather than a hanger, so I could get plates engraved and rivet them on over the "For race use only" etching. In a legal way of course.....:gob:

[MSTRS]

You could go to a bit of bother...but if your cans are not 'obnoxiously' loud to start with, the wof tester probably won't even notice

[kinger]

Mate...they're so in your face that your cheeks would pop if I blipped the throttle.
The spitting farting and flames on overrun just leaves me grinning so much me cheeks stretch. On this thought, maybe switching cans would be easier, eh?.

[Pancakes]

Stainless sounds nice and "raw" too! Lots of places will be able to make one up, can be good value v.s paying for a name brand. Poor design can mean holes on power delivery and poor mixtures in your engine, those bike factories ain't stupid either! Good luck Boobie! I made one for mine out of perf tube, stainless woo, and a carbon tube, needs new jetting before I'd run it all the time.

That cant be cheap :shutup:

Cheaper than if you've got fuel injection:innocent:

[Boob Johnson]

Cheaper than if you've got fuel injection:innocent:lol I bet :sick:

[Hitcher]

Two Brothers Racing. I am most content with the cans that grace my FJR.

[Pancakes]

Depends on the state of tune now and how much difference new cans make to the flow, not just in volume overall but at different stages through the revs and load. I know enough about it to say I'm not the person to say anything about what difference it would make to your bike!! Ask someone you trust or a few people and see what the answer seems to be. Doesn't have to be a killer but I doubt doing it right is ever going to be a fast or cheap job.

[qldzxr250a]

I got a Leo Vince system on my gixxer......sounds the bizzo. nice deep and above 7k damn she howls. :yes:

[Boob Johnson]

I doubt doing it right is ever going to be a fast or cheap job.Yeah I think your right there Pancakes, wise words mate. Im trying to do it on a budget. Just seems like madness to spend such a large amount on it, considering what I paid for it.

[Pancakes]

I've been on bikes with loud pipes I lusted after and the drone got into my head in all the wrong ways when I was out for a cruise. Fun in town, blazing it up and pissing cars off but something else to think about before dropping any coin.

[Hitcher]

With ears full of rubber grommets, a helmet on my head and the wind going past it at speeds in excess of 100kmh, I can't actually hear much noise from my exquisitely customised exhausts. Meanwhile, in roadside paddocks, assorted farm animals are fleeing for their lives...

[vifferman]

Does it always end up in requiring the carbs to be re jetted? That cant be cheap :shutup:
Sometimes all that's required is shimming the carb needles and adjusting the idle mixture. If you do it yourself (like I did with my VFR750 and VTR1000), it's very cheap ($0.00 in both cases).

[Boob Johnson]

Just found a local guy (parts dealer), races bikes etc (reminds me of that mechanic off Mad Max lol). Real friendly dude too, gunna custom build me a can to sound deep & throatie etc & wont require the carbs to be re jetted for $300 fitted :Punk:


Rock on spanners Watson :scooter:



ps: any Taranaki riders want this done, "TAP" in Ngaire is the go.

[MSTRS]

That is real cheap. Keep us posted for the result. If it's all you expect, I think the Nqaire guy will have a number of orders....
PS - when you see him, tell him the Eliminator indicators did not work and had to get another pair - wrong resistance in the bulbs

Yeah will keep u all up to date on the custom can. Ill prolly go ahead with it next week. Would do it tomorrow but he wants the bike for two days but im keen to go for a group ride on Thursday

[ynot slow]

Seems a good guy heaps of knowledge,how the hell he knows where/how his parts are beats me,has absolute shitloads of stuff,seems everyone who has operated out of the Ngaere garage was into speed, be it bikes or speedway,few late nights held there before.

[Hitcher]

The Ngaere Garage brings back many happy memories. I remember when it was owned by Geoff D'anvers and then Alan Jago of stockcar racing fame from the early 1970s. Alan operated the Taranaki VW franchise from Ngaere for a number of years -- I even bought a 1302S Beetle off him.

He is a nice guy, very helpful, wasn't his fault that indicators were wrong for the bike (I was trying to get a particular 'look' to suit the bike). Let him have the bike for the time he asks...sometimes certain adjustments are reqd and these things can take a while, tho not usually. Patience Grasshopper.

oo pick me pick me!!

i got my RF a couple months back and the first thing i want to change is its can too
sounds like you might be onto a plan Boob, be interested to see how it turns out....

[avgas]

Deepends on what sort of growl you want (ok mabey i was a little obsessive about previous.......ok i admit, i did actually sit down one day, and analysed bike noises).
If you want a deep down, throaty growl like a rotty in a mob patch. You cant go past Laser pipes. Ugly as fuck though. But if you need a sound comparo ring klown tell him to run out to the garage and start his bike.
If you want to pick up the thunderous pulses of each stroke - two brothers.
If you want a mid-range howl like a timbre wolf, Micron
If you a low down scavenging roar - Supertrapp
If you want a nice note - like a tuned piano - custom chambers.
If you want hp, top end demon howl - Yoshi's
If you want loud bike noises (as in the same noises just louder) - Staintune.
Right i better go have a wank now cos i got myself all hard.

[Delphinus]

Good read avgas.

What about the RPM brand?

Local bike shop here have some carbon fibre ones on the wall for about $300.
Said the company usually do car exhausts and do the bike ones on the side. They have thrown a few on and dyno tuned and seem happy with em.

I used to watch him race at Stratty speedway. Ill never forget the last time I saw him, he was coming last & with half a lap to go he passed the entire field ON THE OUTSIDE & won lol, just amazing, damn that VW could go :Punk:

Stick a bypass resistor over the indicator to shunt the majority of the current. Usually fixes the fast flash-rate problem.

I think they stole the design from other co's. RPM's car mufflers seem to only have a decent growl from about 1/3 rev (made them good for vvti, vvt etc). I imagine looking at the bike pipes that they are a more top end growl.

Thats fine, I don't have any real power below 4k anyway (14k redline)

[vifferman]

If you want loud bike noises (as in the same noises just louder) - Staintune.

Not Eggs Zachary. At least not for my Satantune high-mount.
Satantune with full spud = similar to stock can (actually quieter than some!)
Satantune with spud with 'tail' cut off - louder at higher revs, but not obnoxious.
Satantune with no spud = rather loud, and howls at high revs (due to smaller internal volume than other aftermarket cans). Gets on your wick after a while (and presumably really pisses off the neighbours).

[kinger]

You cant go past Laser pipes. Ugly as fuck though.

Horses for courses I suppose, but compared to standard cans, these are a huge aesthetic improvement...

..and i refitted them last weekend...oh that grin came back.:yes:
Don't think they still make these though.

[Boob Johnson]

Ok just got off the phone with "Fly" & he has confirmed the new can for me RF900 will be $350 due to the 3 point flang fitting, some bikes can be done for $300 & that's fitted without the need for re jetting.

Ill be getting mine done as soon as poss, seems theres a waiting list :crybaby:


Again anyone keen on doing the same flick me a PM & ill put u in contact with him :niceone:

Last i heard they were bought out? Someone mentioned Vance and Hines.....but dont quote me on that.
The streetfighter guy out west (TM: "Soux") has some bloody loud pipes for sale if anyone is keen.
Those are some of the nicest cans that Lazer produced Kinger. There carbon cans and 'carbon-look' cans aren't as nice. The shape was right, but the badge just ruins it.
