I live in Yorba Linda zip code 92887. And want to do a full custom job for a J-pipe and exhaust system. I'm looking for the best place that uses the best materials. If it is the best I'm not too concerned about price. What should I be looking for as far as materials go? and what setup should I get for the best performance? how many resonators? cat? pre muffler? what kind of muffler? oh and I'd like it to be as quiet as possible without sacraficing performance if that is even do-able.
