Muffler

Good question, I've heard the long "poo poo" pipes do ok, but I wouldn't know from personal experience as I wanted a performance gain as well. With that in mind I got the SBP tuned pipe and extended the glasspack to quiet it down (four rivets, chunk of conduit, screen tube, and fiberglass insulation is all), which actually worked quite well in combination with the length of heater hose on the very end (they also sell an additional tip muffler as an accessory... but I don't have it);

If yer not too concerned with it's lack of visual appeal, this modification helps baffle the intake scream quite a bit;

Here's a few vids on the subject - bear in mind that my cam doesn't really do justice to the subject and this was before I did the glasspack extension;

These mods combined result in the clutch whine becoming very apparent, so you might wanna attend to that as well. There's been a ton of suggestions regarding that - I've found a coupla coats of rubberized undercoating on the inside of the clutch cover does a pretty good job.

I cant even hear my engine running, maybe you should turn your idling down and make sure your muffler gasket isnt leaking. and dont forget theres also noise coming from the intake,which i installed a intake hose and pipe with filter screen to cut down on noise.
i used pieces of rubber hose inbetween my fins on my engine sides and top to get rid of rigging noises, and for the clutch rubbing on cover i used 3 gaskets.
