Anyone heard of flowtech mufflers?
Check the raptor one out... any comments?

If you're serious about your car, man, you don't wanna go w/ that thing! Try a Greddy, Apexi, DC sports and there are a few other ones out there. If you bought that it would be a waste of money. If you're looking for just the muffler, Weapon R makes an ok one.
