Thread: Exhaust - Save money or delete res?

Good answer. And as for the 3" dp question from a previous poster, I don't see the little downpipe being 0.5" bigger creating a huge difference. I appreciate all the feedback, I will definitely leave the resonator on. My car already sounds pretty great and fairly loud(loud enough for my liking about 3k rpm). I think I'll be happy with just the new dp and save a good chunk of change too.
