HFC DP + MPE versus BCS HFC DP and cat-back powervalve exhaust

Bee Pee · 09-09-2014, 06:43 AM

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.

Thanks for sharing the sound clips!

Did you get your 397 wheels fitted yet?

Darci,
Got them at home and they look great in FG.
Went to fit them last w/end but my trusty trolley jack sh@t itself.
Got some new seals so just need to re-assemble jack and then they'll go on asap.
Will send you some photos once on.
PD

Sounds amazing just makes me want that downpipe even more! Mines getting fitted next Friday, seems like ages away...But I know it will put a big smile on my face when I hear the finished result.
