I just had a quick question. Currently I have a DC 4-2-1 ceramic header, no CAT and a 2 1/4 mid pipe that goes to my R1 Racing muffler. It's loud..very loud... I want to make it quiet..If I put a stock muffler like say off a stock honda or acura on...will it drown out the noise from my exhaust? How will the engine bay sound? It's been so loud since i've heard a engine bay on a civic without having to try and drown the sound of a muffler...
