Mid-Pipe Question..

[Brunei1M]

Hi,

Supposedly....if i were to change the mid-pipe of my F10 M5 for a Straight-Thru type....is this Mod worth it? Any owners out there have mod or changed their mid-pipes yet? Thank you for your time

I have cut the entire exhaust out from before the resonators and Dynod it with basically open downpipes. It sounded really mean but didn't gain anything worth while on the Dyno.
I originally thought they were cats but I was wrong.

The stock exhaust is really beefy.
Until boost is increased there really aren't much gains there.

Did you happen to get a sound clip? Thinking of doing the same for my m6.
