ok so I was looking trough ebay and I found a brand new 2002 R6 muffler so I was wondering will my bike sound good? would it fit? what would i have to do to put it there? I know some welding and stuff but i was also wondering should i take it to the dealer and let the mechanic do it for me? heres a pic, well nevermind cant put a pic in there
thks!
A. Picture doesn't work
B. Search "R6 muffler" you'll find all the info you need.

:thumb: thks
First off the picture isnt there....
Second do an "exhaust" search. Theres guys on here with custom flanges and such to get you going.
I believe cutting off your stock can and fitting the R6 muffler with a flange can work. Yeh a custom exhaust shop could do it up no problem.
thks!
I dunno how much they're asking, but I've got an '04 R6 muffler. Perfect condition.
If you want it, make me an offer.
Holy crap, I was JUST about to ask about installing a R6 can. I searched for "R6 muffler" and all I got was WHEELIE!!! and this thread. I was wondering if the stock R6 can is a good match to a lunchbox, because like GON said, they're cheap, and I guess I can buy one from An.
Sorry Chuck. I can't sell it to you.
:laugh:
j/k
Woot: We have a new Teflon Nick.
so what about rejeting? I would have to do that to huh? :mad: what do I put?
search for jet matrixin faq section
For my purpose, I just want somebody to confirm that a stock R6 muffler counts as a "free flowing performance enhancing" muffler when placed on a GS in terms of rejetting. I think it's obvious, because of course the stock R6 moves a much greater quantity of air than a GS. But just because it's obvious to me doesn't mean I'm not missing something and I'll waste money and time by trying it. I don't see any threads where someone has installed a stock R6 can, it's usually an aftermarket can designed for the R6, which is probably a different ballgame.
I'm not going for the look or the sound, I'm going for airflow to match the lunch box, and cheap, which looks like the stock R6 can can provide. Which I guess is why it appealed to GON as well. :)
I'm hoping since I capitalize and punctuate and try to submit legitimately informative posts, and I did try searching, that someone will be polite and say "yes, user X installed a stock R6 can and it works great" instead of "search n00b." Thank you.

Since you did all that, I'm gonna try and find the pictures and thread with the stock R6 exhaust for you. :)

The GS moves 244cc of gas at a time, while the R6 moves right around 300cc. It wouldn't be considered that much more "free flowing" especially since it is a stock muffler and has to conform to the same emissions and noise standards that all the other bikes do.
I can't find the post about the STOCK 6 can. just this one with an aftermarket. (http://gstwins.com/gsboard/index.php?topic=27572.msg292169#msg292169)

That's the kind of talk I was looking for. Thanks Alpha, that gives me a way to think about it. Now if I go (for example) from a 127.5 jet to a 150, that's theoretically about 18% more fuel. Even with those numbers, the R6's 600cc displacement is 20% more than the GS's 500, so it seems about right. Additionally, the R6 has a higher compression, which increases the amount of uncompressed air that has to exhaust. Higher RPM also increases the volume of air that needs to pass through.
Once again, I could be missing something that makes this analysis completely wrong.
That actually kind of gives me more reason to think it would work. Maybe it's my civic duty to try it and report the results.
I think you should. Bolt it up, then get sick of the weight of it, and try an aftermarket R6 pipe.
Okay, I'll bite. What's the weight of it?
so chuck would you buy an aftermarket R6 exhaust or stock? stock would make the bike uneven huh?
The R6 muffler is 7 lbs, as far as I know. I don't know what the GS can weighs, but if that's a problem I can just skip that sandwich before I ride. :laugh:

Unfortunately that's not how it works. Just because you have a freer flowing exhaust doesn't mean you're increasing the air being drawn into the engine. Remember, exhaust valves are (for all practical purposes) entirely closed when air is being drawn into the engine. Therefore the effect of an exhaust change is not nearly as beneficial without an intake change. Stock headers on the GS also restrict most of the gas flow out of the engine. Just changing the muffler is going to do little to no good if the header pipes stay the same diameter.Also, higher RPMs don't necessarily mean higher volumes, just higher exhaust gas speeds, meaning how fast it needs to travel through there. Let your bike idle one day and stick your hand at the ned of the muffler. You should feel a distinct puff puff puff. Rev the engine and feel it smooth out into one continuous stream.

That's a great point. I didn't think of it that way. (I am planning to run a lunch box, though.) I also didn't think about the fact that it's the pressure exerted in the exhaust stroke that drives the exhaust gas out. The R6 just plain has more power, and can use more of it evicting exhaust gas without it being a problem. So an exhaust from a higher displacement bike could very well be
more restrictive, and it wouldn't really matter for that bike.
That blows my theory out of the water, then.

I meant volume-per-time, which is necessarily more when the RPMs are higher.
In all, it sounds like you believe there's no performance benefit to be had from replacing the can, then? That would sure save me a few bucks, and a few decibels. :)

No matter what bike you have, replacing just the muffler/silencer/can makes little difference in performance. On most bikes you'll only see a 1 or 2 HP gain at the most from a slip on/bolt on can. Replacing a stock muffler with another stock muffler is just wasting your time, I feel.
dang you are smart!! (not trying 2 be a smart A$$)
A little off the subject, but I'm wondering how my '89 will do with the new lunchbox I'm getting, matched with the Cobra F1R muffler that's on it. It sounds pretty rowdy, but it isn't a straight-through baffle design... Maybe I'll start with a 140 main jet to see how that works?

Unless, as in the case of almost any stock Mazda running around on the street, the stock muffler is so horribly restrictive of flow that it merits a change even if the rest of the setup remains stock.
My sister has a '01 Protege 2.0L that picked up 5-6mpg in city and highway, freed up the top-end rev range and although it hasn't been on a dyno in its life, seat of the pants tells me it is 5hp or so.
Parents have an '02 Miata 1.8L that has similar effects from a muffler swap. Adding a high flow foam element with an entirely redesigned "cold air" intake scheme mainly added noise, it was the muffler that changed the characteristics.

I disagree. Wasted power is wasted power. R1 headers are bigger in diameter than R6 headers because the R1 is always moving more air.

I'd suggest waiting until you get up the gusto to go to a full system exhaust. Anything that retains the stock GS headers, be it Wileyco, mak's "custom" high- or low-mount or an R6 stock muffler, is not going to do much for you.
Another point, as has been pointed out in this thread before, the R6 can (in like new condition) is not going to be much, if any, louder than a good condition GS pipe. A blown out GS pipe may, in fact, be louder if the baffle is rusted and leaking.

I actually like how quiet the GS exhaust is. I was going to reluctantly accept an increased noise output in exchange for a slight improvement in power. However, if the improvment is so slight I'll never notice, then I'll just wait for the gusto, as you suggest. I bid $1 on just about every R6 pipe I found on eBay, so if I get one of them, I'll probably try it out. :icon_mrgreen:
My current GS header is dented, so it's probably somewhat more restrictive than most. I suspect that will be a problem anyway. For now, I'll see what I get out of a lunchbox and rejet, and punt the exhaust question for a few months.
Also, if I want more HP, I suppose I can ride my FZR. :laugh:
Why not try an FZR muffler then? :laugh:
Hey chuck or wondertwin have any of you drilled holes in the stock muffler? I was wondering how would it sound or where in the can you drill it at
Everyone who's tried drilling their stock muffler has said it was utter crap. And then, they can't un-drill it.
Funny thing about the FZR, I bought it with a V&H supersport on it. It's so freakin loud I was thinking about going back to stock. (I have the stock can, but no stock headers right now.)
can you put 2 exhaust in a gs500f 2006 instead of one? i was looking at the sv1000s with custom exhaust i was like wow :o

I had totally forgotten about this fact until you mentioned it. Also, in regards to the gen 2 rx-7 there can be as much as a 15hp increase just from the mufflers and cat change. With headers it can be as high as 30hp depending on the engine. It is unbelievable how much they had to choke up the rotaries.
Yeah but rotary engines are notorious for incomplete combustion. Not as bad as a 2-stroke, but that cat does a lot of work.
chuck how can you remove the baffle in the stock muffler? NVMD lol
ok the 2006's exhaust, is it diff to drill than older models?
Quote from: GON on December 13, 2006, 12:54:49 PM

No.
Ok, don't drill your pipe, I did, sounded like a lawnmower fighting a swarm of hornets. If you do drill it, drill holes small enough to put screws in when you decide you hate it!
Wileyco sounds much much better!
As for the debate about the header of the gs, seems like the pipe is plenty big to handle the exhaust flow. The motor can only make so much flow, stock. Dollar per hp seems as though its not at all worth it. Just my opinion though.
I'm not trying to be a jerk or anything but anyone looking to add major hp isn't going to get it unless they modify the engine, and I mean bore/stroke or add spray to it (which can be done for about the same price as a top end exhaust).
If you get two staws: a thin coffee stiring straw then a bigger staw and attach the larger straw to the opposite end of where you blow through the thinner straw. Does it make it any easier to blow through the thin coffee straw?
The restrictive part to the exhaust is the header, then the pipes, and then finally the exhaust. So any significant gains would be found getting a wider exhaust header, tubing, and then a muffler.
I'm not that familiar with motorcycle engines but I have worked on cars a little, so i'm just chipping in my $.02 so no need to flame.

I drilled 3 holes in my stocker. I like the sound better with the holes, and it seemed to run a bit free-er after I drilled.

$250 bucks for a Yosh is pretty damn cheap...but yeah, that same money would go a long ways towards improving the suspension or tires on an otherwise stock bike as well. If you've already got a different shock and stiffer fork springs, why not spend half a paycheck on a full system? I won't argue your values though...everybody is different.

Major HP on a GS=cams and displacement, along with porting and big carbs. Or a turbo.

That's why a full exhaust system is the only way to actually change the characteristics of the engine beyond sound (as stated above).
250 bucks, if you can even find a yoshi, and gooood luck. For like 2 hp? Your not gunna pull and extra 10 or 15 hp out of her.
I've put headers on a few cars that actually had restrictive stock pipes and the difference would make you grin from ear to ear! That's not happening here. But more power to ya if that's on your list of mods!
One of my other bikes is a kz750, with a rejet, pods, and a kerker pipe she'll ripe your arms off. That's what I'd expect.
Again what ever floats your boat!
I found one for 250 with a jet kit...
Have you ridden a GS with a Yosh?
No I haven't, but I know what 2hp doesn't feel like.
When in Rome...
so a full system is better than a slip on?
A full system is better than a slip on if you can afford it. Full exhausts are expensive - and unless you just like modding and have spare cash around its not really worth it on the GS.
Like Ixolas said you need both less restrictive headers as well as exhaust. The GS simply isnt capable of giving you great performance boosts.
oh i c thanks

Although discontinued in 1994, the Yoshimura full exhaust system is said to produce the most power of any full system for the GS500.
So yeah... reading... I post the Wiki whenever you ask a question for a reason, dude.

What?
You can't stick a full system from a 4-cylinder bike on a GS (which is a 2-cylinder bike). Not unless you have some mad crazy tube bending and welding skills. Yoshimura discontinued the GS500 full system, not other bikes'.
Hey alpha can you make a gs sound like or even a little like a big bike?

Considering those bikes are inline 4s, and you have a parallel twin, no amount of pipe trickery will get it to sound like a big bore inline 4. If you want a deep sound, then get an aftermarket slip on and have it custom fitted to your bike.
i c, how would the slip on and full system differ? besides being a full system :icon_mrgreen:
have a look on the wiki, there are 2 sound/video clips of mine and tricuris's gs's with r6 link pipes and race cans,
mine sounds the bee's knees and i think sounds better than most 4's its got a nice deep lumpy note. love it :thumb:
