Hello fellas! i was turned onto a possible lead that maybe the baffle inside the stock expansion chamber may have rusted apart and is causing problems with my quad... i know a good aftermarket exhaust would be ideal.. and one day il make it happen. but for now, is there any modifications i can do to the stock pipe to make if more effective? would taking the baffle out of it help at all? would taking anything out of it help at all??? i read that just about all (if not all) the aftermarket pipes have nothing inside them... i just seen a forum on here that a guy used a boroscope inside of a stock pipe and theres all kinds of stuff in there... what do you guys think??? the silencer i have isnt stock but im pretty sure it just came off another bike... doesnt look like anything fancy and it doesnt have any markings on it that i have noticed.
