Matching finish and phenomenal sound, not pretty just phenomenal. They come unfinished BUT they are all welded in stainless steel. My LS4 SS finally sounds like a V8 SS. If you want crazy volume, need overcompensation, etc., get the Flowmaster. If you want to get the very deep rumble of a muscle car and still enjoy your own $5,000 sound system, this is for you. I painted mine with extreme heat paint just to increase corrosion resistance.
