RV Guy said:. I don't want it to be much if any louder in the interior. Do you get any resonating?
Since the stock exhaust is virtually silent, yes, you will hear this system from inside the car. IMO, once installed, my car finally sounded the way it should have from the factory. Obnoxious...no, but a nice healthy rumble at idle and stomp on it and it sounds like a Vette should! Although there may be some resonance it is minimal at best. You can still listen to the stereo or hold a conversation. Even now w/ my headers etc... it's still pretty civil until I get on it.
