I'm thinking of upgrading the exhaust on my 2002 M2. I actually like the way it sounds with the stock muffler but it doesn't alert somnolent car drivers the way the Norton does. I figured I would just get a V&H slip-on but I've been reading the threads about cutting and modifying the stock muffler with interest. That's because I don't care for the prospect of repacking the V&H and I'm also cheap. The question is, is there any proof (dyno, etc) that either one will improve the performance of an otherwise stock M2? I think my bike runs well but there is a pretty big dip in the middle of the rev range. Will either modification cure that? I'm planning on rejetting the carb regardless and I'm running a K&N filter in the stock bread box but will probably modify the bread box. Thanks. | ||

I've never repacked my V&H. Jetted appropriately, running just the perforated tube on my S1W, sounds and runs awesome. For what it's worth, years ago, my butt-o-mometer power gauge told me my M2 made more power on the race muffler than on the SS2R I took off. But since I can't find a race can for an S1W these days...I run the SS2R and it works just fine. And I like it a lot better than the blaaaattt sound the Supertrapp on my S2 makes, LOL. Think about the CF 'race' air cleaner, too. I like the performance, and it clears up a ton of right knee room. As for the dip, make sure your plugs read a good fuel mix. The race can on my M2 (again, years ago) made great midrange. The SS2R is stronger than stock, but not as strong as the race can. Dunno about the reworked stocker, sorry. | ||

I have the V&H 999r slip on on my '98 S1. I like it a whole lot. The thing makes great power, its not obnoxiously loud, although I am certainly heard coming down the road at sane speeds. When I really twist that throttle, I cant hear anything besides the roar of the bike. The can has been run on that bike for about 5k miles, and I still have good plug readings and no problems with the packing. (Message edited by milesvdustin on August 29, 2007) | ||

I run a Supertrapp IDS, which noticeably filled in the midrange. Great sound and is adjustable. I prefer steel to aluminum. The Trapp is very solid. They run 300-350$. I have heard good things about the Wileyco. I have seen new ones going for under 200. To have the can professionally rebuilt ( ie.. Drummer ) is not cheap. You mention inexpensive, I would go w/ the Wiley. | ||

Can you change the tranny fluid with the supertrap installed? | ||
| Warlizard |
Good question Nate. I don't know yet, I will take a look. My guess is no. | ||

Can you change the tranny fluid with the supertrap installed? NO, it will make a mess i take it off with the chin faring. | ||

I would use the V&H SS2R over the the reworked stock exhaust. The weight savings, better sound, ability to repack and my perceived improvement in performance. Joe | ||

"ability to repack" You perceive that as a good thing? I'm also measuring the stock one for re-work, just wondering why having to re-pack every 3 to 5 thousand miles is better than never having to re-pack it... | ||
| Sleez |
both mufflers need repacking from time to time | ||
| Warlizard |
I don't like the idea of repacking either. I imagine that if the packing worked itself loose, it could cause serious problems. With the Trapp you use discs, that don't need changing. You can also adjust HP and sound by adding/subtracting discs. Again, I also prefer stainless to aluminum. | ||
| Jayvee |
OK, I lost track of what we're talking about. Stock stock muffler never needs re-packing, right? Even a Drummer-type modified one. Buell Race Muffler does need re-packing. Vance & Hines does need re-packing. SuperTrapp? This one I don't know.... | ||

Repacking isn't a big deal (ten minutes and $8) - the hardest part is removing the muffler, so I repack the V&H every year (about 12k miles) during a primary fluid change. It's wrapped around the perforated core, so it really can't come loose, or harm anything if it did. That said, I have a Supertrapp on a cafe Sportster that I also like, especially now that I have the number of discs dialed in. | ||

A slip on muffler & airbox mods WILL get rid of the torque dip you get with the stock bits, but only gain 1-3 ponies on top. Max. That's ok, since the M2 is a torque beast, not a screamer. IMHO. I have a Wileyco Ti slipon, and it's louder than stock, ( hard to sneak through the 'hood at midnight ) but quieter than some. Repacking is not a big issue, just do it when you change the primary fluid, if needed. ( seldom with a Wileyco, more often with a race can ) Removing the muffler makes fluid changes a neater job, by far, so what the heck. Get the muffler you like the sound of. ( the Ti Wileyco is feather light fyi ) I think the best leg clearance is with a modified stock airbox. My knee hits the carbon race filter under hard braking unless I pay attention, not an issue with the breadbox. My reasons for changing were cosmetic, not performance. The modified airbox flows more than a stock M2 can use. There was no need to rejet when going to the race filter. You WILL hear valve train noise more with either setup. See the knowledge vault for details. There seem to be 2 setups that work best. 1. seal the holes in the stock Helmholtz tube ( milk jug caps ) & add conical K&N filter. This is like an enclosed elbow style filter. 2. remove Helmholtz tube, replace with venturi ring. Remove air filter internal housing, make bracket to hold stock K&N replacement. ( this is the way I did it, & it flows fine ) | ||

The Buell Pro- Series exhaust is the Supertrapp. Good enough for Erik, good enough for me. | ||

Dwardo: I run a Wileyco on my M2 and a modified stock muffler on my S3T. I like them both. The modified stock is "tuneable" for noise level depending on how much you open up an internal end cap. I have mine tuned so that I cannot hear the exhaust at 70mph with a full face helmet and ear plugs. The Wileyco I can hear at any speed that I ride at. Seat of the pants feels like they pull stronger at high RPM. Mark Mark | ||

Are the symptoms of a needed repack obvious? I've had my SS2R for probably five years or more now and haven't noticed anything different about it; sound, power, nada. Albeit I haven't had the time to ride it like I would like to but there's probably 20k miles on that exhaust. I'm taking lots of stuff off this winter so I'll check into it then. | ||
| Dwardo |
Thanks, guys. Now I'm leaning toward getting the V&H. Maybe over the winter. I've been concentrating on making it right before doing any mods. Next task will be to clean and re-jet the carb and replace the intake manifold seals. Once all that is done I'll have a baseline for comparison for when I do the exhaust. | ||

> Are the symptoms of a needed repack obvious? Just a bit more noise, which you may not notice as the change is gradual and small. The first time I changed it for no particular reason, and once done the difference was subtle but noticeable. | ||
| Kyrocket |
Thanks Frogmaster, I have to replace the base gaskets this winter and while I have it apart the oil pump gear and primary tensioner shoe are getting replaced. And the exhaust is getting eyeballed as well now.  | ||

"I think my bike runs well but there is a pretty big dip in the middle of the rev range." The biggest single improvement (slight though it was) I ever made to my exhaust was replaceing the stock header with a Pro Series race header that came in the factory race kit. This made a bigger seat-of-the-pants difference than putting an aftermarket muffler on the stock header. Muffler availability is limited and expensive with the race header, though. | ||
| Warlizard |
The Trapp will fill in the middle as well. Throw 20 discs in and you are set. Maybe not quite to the level of adding a race header, but the headers will run you an extra 500 bucks. If you want more off the line power, go to a 26T sprocket. | ||

No repack of my SS2 after about 9k still sounds right with great power. Yes you can easily change the tranny fluid with this muffler in place. It will get covered with some fluid just wipe it off. |
