My Ride: 2001 M3
Just a heads up, but I am running stock software with supersprint headers and supersprint cats and I have no CEL. My code reader lists a 'pending' code for the rear o2 and the light came on briefly for a day, but I have been driving around for 2 weeks now. I had the shark injector installed, but removed it so I can have a custom tune done(being installed next week).
2001 Phoenix Yellow M3:
Schrick cams - AFE intake - Custom Tune - Supersprint full exhaust - Evosport pulleys - UUC Evo 3 short shift kit - Brembo 14" BBK brake kit - Euro rear floating rotors - TC Kline Double Adjustable coilovers - Vorshlag caster/camber plates - Adjustable rear camber arms - Black 2005 competition package interior - Vorsteiner CSL front bumper - 19" CSL wheels
