new exhaust sounds great. got a new O2 sensor... of course the one they have listed for Bosch 99 GS isn't right (13425), so I got pt no. 13399 (avenger 4 cyl). car sounds and looks great... still getting crappy gas mileage, stuttering, backfires, and no power at all under 3k rpm. guess i'm going to mess with plug wires and coil pack next... :S this suxxx...
