the car we used to test fit the kit already had a y-pipe on it. so the exhaust was a bit louder than normal. with a stock y-pipe and manifolds (as most people have) the exhaust should not be too loud. if you get the flowmaster, it will be louder than the dynomax of myagnaflow though.
we'll try to have sound clips soon.
