yea those numbers do seem pretty extreme (no disrespect to what you have). I have the SAME EXACT setup BMS Dual/ Cobb AP and I JUST ordered AR Designs DP's last night and I'm NOT EVEN expecting to be NEAR those numbers..... If I can get 350whp I'd be thrilled....
Any idea's what my car may pulll with the BMS Dual/ Cobb AP (w/ pro tune) and AR Catless downpipes on 93 octane?
My only down fall and to me is that my 135i is and auto.... I HATE THE DRONE that auto's make with an exhaust so I'm gonna be searching ALOT fora decent midpipe (no cats) and axel back..... any suggestions; has anyone heard a 135i with the TBE on an auto and how was the sounds?
Much appreciated Thanks guys!!! BTW- been trying to search this with no luck!!!
