HFC DP + MPE versus BCS HFC DP and cat-back powervalve exhaust
I met up with another EWG M135i owner last night with a fad gadget sound recorder.
Link below is thread on babybmw website with recordings of my car [HFC DP + MPE] and his car - HFC DP and BCS cat back exhaust which has boost activated powervalves, which he'd shimmed open. http://www.babybmw.net/viewtopic.php?f=74&t=65935 Enjoy !!!
