I picked up a M2 from the original owner and it is all stock which is nice, but I like a little more noise so that my chances of being noticed are improved. Any recommendations greatly appreciated. Thanks | ||

Search the knowledge vault there is some info on modifing the stock exhaust. Or buy a force. | ||

Probably better off getting a headlight modulator and a yellow jacket / helmet. seriously... | ||

Ride to notice them. Don't rely on them to notice you. Enjoy the quiet ride. | ||

The noise won't help you get noticed, it will just annoy people around you and lead to legislation that will make it impossible to modify a motorcycle with aftermarket parts. For the M2, you have a good option for a lighter aftermarket exhaust if you can find a Supertrap IDS (internal disk system). Great pipe for a tuber, and makes primary fluid changes easier also. Throatier, but not that much louder. Won't help getting noticed but sounds nice without getting to the level where you are just being a selfish attention seeking jerk. | ||

To answer your question try a D&D or as mentioned before a Force pipe | ||

How about a PRODUCT IMPROVED OEM muffler up-date ??? Pictures if you want them, just PM me ,,, | ||
| Mhlunsford |
If you have a mod to improve the OEM, that would great - could you email them to me : Mark.H.Lunsford@kp.org Thanks | ||

Hey, I have a M2 Drummer I doubt if I'm ever going to use. Not the cheapest muffler you might find, just throwing it out there. I live in Pinole/Hercules area. | ||
| Buellistic |
If you want to REALLY MAKE NOISE put on a REVERSE CONE MEGAPHONE !!! | ||

So, I have been teaming up with a friend to design a new pipe for my M2  It is a 2.5 inch straight pipe with an internal replaceable baffle. Next year will be a fun year to ride! | ||

More details to come as the project moves along... | ||

I just switched back to stock muffler after 13 years with a v &h. and with that the bike is soooo smooth and sooo much more torque below 3400 rpm, which is where I ride about 75% of the time. sure it lost that top end that used to pull me off the bike, but the stock is still really great sounding around town. and now on the highway, I get to hear more wind noise. | ||
| Jayvee |
Yah, the bad thing about stock exhaust is you can hear the engine! Sounds like its shaking itself apart... | ||
| Bluebueller |
True True. I have been a little worried lately, like its gonna blow a bearing or something.... that is one noisy motor (Message edited by bluebueller on November 02, 2013) | ||

Just listen for changes in the noise. I went through it when I pulled the race muffler off my S2 (finally found a stock S2 muffler!). As long as it's the "same-noisy" every time I ride...I don't sweat it  | ||

I'm curious what your baffle looks like. Got any pics? | ||
| S1owner |
Ness has the se type of exhaust with magnaflow coming out | ||

If you can find a SuperTrapp IDS Muffy,I have found that 10 discs and an open end cap (inside the can) yields a nice balance. It'll sound "civilized" but not quiet around town, but it will really speak with authority when you wick up the throttle. The best of both worlds, really! | ||
| Buelljunkie |
I understand you're leaving the turnout endcap in place, but if you have an open end cap inside, I can't see how the # of discs you have would make any difference. Without a closed end, you lose all tuning capability. I guess the discs could still marginally act as a baffle...? | ||
| Buelljunkie |
Koz - I'm still interested to know what your baffle looks like from the pic above. | ||
| Flyingyankee |
The open end cap is for supposidly for "Racing Only", but its still tunable. When installed it, I experimented with the number of discs like you would with the closed end cap. As you probably already know, the number of discs installed increases the back pressure, though not as much as with the closed end cap. I consulted with a SuperTrapp Rep about this and he confirmed this. I was able to tune it the way I wanted, but with an open cap, you need more discs to achieve the same datum point than you would with a closed cap. I found the closed cap too quiet for my taste. My profile lists the mods I did to my bike and with this set up, she's performs very well. | ||

I am looking at trying out two different types of baffles. The first would look like this  The other is made by Cycle Shack and I am guessing would be a bit quieter  | ||
| Buelljunkie |
Flying - That's interesting, I wouldn't have thought tuning was possible without the endcap. I put an IDS muffler (and an American Sport Bike carbon air cleaner) on my '02 X1 and started with 14 discs, it really felt like it was choking the bike. I did try it without the end cap also and I felt there was no restriction on the exhaust and it revved much more effortlessly. It was, however, too loud for me & my neighbors. Interestingly enough, the 14-disc closed endcap setup which seemed fairly quiet while I was riding it was considerably louder when I had a buddy take it down the road! I ended up with I think 21 discs and the closed end cap, and am happy with the results. The muffler sounds great without the outer turnout in place, but looks crappy and unfinished. To reinstall it with this many discs I carefully cut off the small flared piece on the inside of the cap with a small cutting wheel. The way the exhaust flow is directed toward the outside by the discs/endcap and along the wall of the canister, the flare seemed to impede rather than assist the exhaust gases' ability to exit. I'm happy with this setup. It still has a nice deep sound without being offensive. Koz - thanks for the pic. I was thinking you might be using something like that, only in my head I was picturing one with the spiral slots in it. I don't think I've ever seen one like the 2nd pic where the exhaust looks to be redirected to flow from the outside in. | ||

I installed a Cycle Shack exhaust on my uncles 2007 Dyna and that is the baffle they use. It is also a 2.5" pipe. Many people drill out the dimpled portion to make if flow straight through. I am leaning toward the first option though. | ||
| Buelljunkie |
There's also the spiral slotted versions. I can't attach a pic...even with a 100kb file it says it's too large. With the different baffle styles and all the different options for the diameter and length of the perforated tube I'd say you've got a lot of possibilities! | ||
| Jayvee |
All you need is a decibel meter and a dyno  | ||
| Flyingyankee |
Gents, Allow me to correct myself, when I said "open end cap", I meant an open style internal disc. This open end "disc" is affixed at the end of whatever number of internals discs you insert into the muffler. The physical end cap with the turn-out pipe remains on the muffler. | ||
| Buelljunkie |
Flying - No need to correct yourself, I knew what you meant. I have one of the open style internal discs you're talking about. When I said I tried mine "without the end cap" I meant without the closed internal endcap. I never tried the muffler without any end cap...it was either the open internal or the closed internal end cap, and in both cases with the outer turnout endcap in place. Either way, I was still surprised to learn that any number of discs with an open internal end cap would make much of a difference in tuning. I guess if I thought about it, the fact that the open style endcap reduces the exit diameter somewhat would have at least some effect |
