I´ve seen Pacesetter Headers for our cars for like $120, and the cat back exhaust for $180. But I have heard that they are so cheap, you might be better to keep the stock one. I´m gonna either bore out my stock header so it flows better or have one custom made. (how hard can it be, mandrel bent tubing welded to the base that looks like your stock header´s base, and tap in a O2 sensor hole)
