umm, not that im claiming to be a vet at car modding or anything...
but when you get an exhaust, you look at performance boost, not looks or sound. if you want a low grumble, cut your pipes off at the header, or better yet, stop by autozone and see if theyll put a nice muffler on there for you. if all else fails, by one of those "apexi style" mufflers off of ebay. i bet those sound great.
