Thanks man but you have one clean e90 as well. That has the n53 right 273hp? I just ordered active autowerkes new headers and software for my car. Right now im making around 275 with the bmwpreformance exhuast and secondary cat delete. With the headers and the tune i get 35whp or 45 crank giving me around 310hp or so.
So if I get that performance exhaust and secondary cat delete, around how much am I looking at in HP? Also, can you describe the sound of the BMW Performance Exhaust? Is it meant for the 330i or is it an E92 M3 exhaust?
