hey,,i have a 02 cavy with a custom cat-back exhaust [2.5inch] with a HP racing muffler and the muffler is very loud. Ive been using this muffler for a few years now but now it seems to be geting nasty sounding. im looking for something close to being stock sounding but still opened up for performance? If you guys could help me out,that would be great. Also I would like to keep the price some what low. thanks
