| I know the cat-back is going to increase the sound level of my car. What I am trying to find out is the sound difference of a high flow cata converter vs a test pipe with a resonator on it. I have a test pipe with a resonator on it and I debating if I should swap it out for a high-flow cat in attempt to lessen the noise of the exhaust. I know its going to be quieter, but by how much?
