going to do a muffler mod on my 600p,,was wondering if a 1 inch inside dia pipe be to much or to little for it,,,i am not going to do a port job on it,,just mod the muff,,,,this stock muffler is a stupid setup,,,,exhaust comes into muffler,,goes through baffeling,,makes a hard turn into a pipe to the outside of the muff and deflector forces it to make another hard turn,,,,picture a big z,,,so i know if i make a direct route it will breath a whole lot better
