i've got some friends with one... they sound like complete doodoo on just a custom pipe, so make sure you have a resonator put in if you're going that route.

if you're just throwing it on your stock exhaust piping then it should sound fine.

don't expect any hp gains in either case tho, the 20hp they tell you you'll gain is about as real as the tooth fairy (sorry to burst anyone's bubble about the tooth fairy).
