so right now I have a stock exhaust system with a gutted Cat, DC 4-1 headers on a D16z6 and it makes this raspy sound and I dont think it gets much power because of no back pressure, I'm pretty much looking for a new set up or stock set up with no gutted Cat. then I come across this on ebay.

Sounds pretty good, I'm just wondering if anybody has any experience with this brand or any other recommendations just let me know whats up.
