Custom exhaust systems?

[short-circuit]

I'm considering a custom set up for the Striple (as well as various after-market options).

Firstly, am I better off to cough up the big dollars and stay with the Arrows/Mircons/Zards/Akrapovics etc? Or will I get a really good system manufactured locally?

I'm wondering about about issues like loss of power or decreased durability/longevity etc. Is it hit and miss with a one off NZ exhaust manufacturer? (who doesn't do extensive research and design testing)


Secondly, if I go the way of getting something manufactured locally - who would people recommend in the upper north island (preferably Auckland). I've had a couple of people suggest Custom Chambers in East Tamaki? Opinions please...

I'd import one if I were you, the Kiwi made stuff isn't bad from what I've seen, but nothing like the Akra/Arrow/Micron systems. Not all of it mind, but given you'd have to work with a Kiwi tradesman, it becomes a bit of a no brainer.

Shame the Micron is out of the game, some of their gear is seriously nice.

Yeah the Microns are nice. I quite like the Akrapovics also (although they are just a slip on).

My my main question though is whether or not a one off made here will be on par with big overseas brands (in terms of performance and quality). If there is a difference performancewise would it be substantial?

[imdying]

Well, even if were deficient by 5 peak hp, your butt would never notice. But if it rapes the curve, you'd likely notice that (your butt might even tell you it's faster because a dip in the midrange makes the top end feel like it comes on stronger). Harris Pipes here in the SI did a system for a local racers 675, reputedly to very nice results, and apaprently looks the part too... that'd be where I'd start if I were looking for a locally made system for my Trumpy.

What about up near the Metropolis?

There's a guy out in Waitakere (I think) making exhausts. I've heard a pipe of his on a Hornet 900 and it sounds NICE. I'll probably be going to him when I'm wanting exhaust work done on my bike.

Do a search on here for Virgin Mufflers (http://www.kiwibiker.co.nz/forums/showthread.php?t=66659&highlight=Virgin+Mufflers) and you'll find lots of his threads. KB name is blade1000 (http://www.kiwibiker.co.nz/forums/member.php?u=12824)

Hmmm - not a good end to that thread link you posted by the looks of things but thanks for the suggestion

Neptune in Welly make very nice pipes.

And I have only heard good about Cycleworks (welly)

As far as slip-ons go, and I may be bashed over this :bleh: from what I see they all are basically the same length. They all run a perforated core of approximately the same diameter. The performance aspect is then done (core size and length). Noise is a result of packing and db killers and these vary. After that it's physical appeal and quality of build. The later varies considerably from the pieces of shite to works of engineering art.

Also remember that the right sticker on the side of the muffler can make it look like it has 20 more hp just sitting still. :niceone:

What about up near the Metropolis?Well, I'd still give him a ring... the racer that he was working with is the Trumpy dealer down here, so given the close relationship, it seems possible that he'd be able to get a bike to mock up with if he hasn't made one already... he also spends time dyno tuning the systems, which you indicated was important to you :)

Thanks for the recommendation. Made contact with Graeme yesterday. Sounds like they did a brilliant job on the Daytona

That was the impression I had from reading the article in BRM or KiwiRider, or where ever it was :yes: I was hoping that a call at least would be worth your time :)

Price for full system was prohibitive - cheaper to buy the Arrow 3 into 1 (at just under $3000). Logistically not worth doing with Harris pipes.

Bike will go into Custom Chambers next week some time. I like the look of the twin stubby mufflers but will be getting something stubbier with a cone shaped end. Also replacing pipe from the headers back (cutting out the catalytic converter). Old system will just bolt on if needed.

Should look and sound the biz

[The Stranger]

Wouldn't it pay to stick with someone who has proven results with your machine?
I know that some of the big boys put a lot of R&D and dyno time into their product. Time and cost that can only economically be recovered over many units. I can't see that low volume manufacturers can match that and remain cost effective and if they did.

You could get in touch with these guys and see what they do for a striple !They seem do do their homework and have dyno charts for all they sell !

[toebug]

I get my pipes made by a guy in Dunedin. I do some drawings with dimensions etc and he builds them to my specs. I have had him made 5 cans for me in the last 2 years and he does an awesome job making them out of stainless steel. The last ones I had made only cost me $400 for two cans!! and then I got the link pipe made locally once again out of stainless. All up it cost me about $1000 to convert my bike from a single rear exhaust into twin exhaust. I doubt you could get an aftermarket system for that price and the local one I am sure will last just as long!

Go local!

[imdying]

Wow, that's big dollars! R&D costs though I guess, wouldn't be selling as many units as Arrow so I guess that cost is always going to be split up at a higher rate. The ol' cone shaped end thing seems to be very much in vogue at the moment, you're not the first to mention that to me recently :yes:

i got Mivv on my adult sized triple, got it through these guys http://www.pjsparts.com/ , glad i didnt get the arrow, saw one the other day and was highly disapointed with the noise, and the price.

Be interested to hear yours at the track (you doing the 28th aye?) Your model don't have the hassels of the CO sensor though does it ?

[short-circuit]

I'm definately keeping a twin pipe arrangement as I am keeping the rear passenger pegs (for the boss). The Street Triple looks good with a single low mount only when the rear pegs and hangers come off (otherwise it doesn't really look balanced). Also I want to stay with the twin bug eyes/twin stubbies look of the Triumph Street and it's big brother the Speed Triple.

So as far as twin mufflers go, I like what Micron do and Akrapovic. The Arrows are a little too pricey and look a bit thin.

Trouble is with the big brands - you pay big dollars just for a slip on.

How about getting some tried and true slip ons and replace mid pipe locally later???

its the 27th aint it?

whats this hassles you speak of bro?

The CO on the 06 are on the cast splitter where it goes from one into two !
Think the 07 CO is before or on the collection box just after the headers so ya can just throw on a slip on can !
And yeah the 27th

if i was going with twin undermounts i would go for the Zards, they look sexytime.

triumph have this funny thing of using all their parts up until they run out, so even though mine is an early 07 with the updated ecu etc, it still has the 06 exhaust system on it. no dramas with the sensor as when you order an 06 slipon the mid pipe has a threaded hole for it.

[imdying]

Oooh yeah, the Zards I've seen are definitely sexy little beasts... they make some cool looking mufflers. Akrapovics are gems too, never seen a set of those I didn't like... The Yoshi carbon ones with the carbon end caps look like something I'd make in my garage in comparison.
