hey where do you live? im in commack, long island, i have the greddy ti-c with a k&n and im about to get the stillen header, wondering if we could meet up so i could hear it in persongalloveda wrote:yea big time... I feel a big difference in whp, at least 12- 15. And with the greddy catback and the stillen intake i probably added another 10 or more hp. All i have to do now is get rid of the cat. converter and replace it with a high flow cat or a straight pipe... dunno yet... The headers sound a lot better in person. My step dad doesnt kno how to rev an engine lol... but either way the car sounds like a goddam beast
