F90 M5 COMPETITION EXHAUST SOUNDS | MPE X EISENMANN X EVENTURI X GOPRO10 |

Is this one with primary and 2ndary dp?

[@brockthomas2804]

How much did the volume increase with the addition of the secondary downpipe? I'm guessing like 20-30%?

[@ckantzavelos]

I would say around there. It is still very civilized and not obnoxious. The addition of the primary downpipe made it unbearably loud, and far less refined.

This still have the resonators ?

[@wuzumaki]

MPE exhaust has a smaller resonator than stock.

[@elion7610]

With opf ?

[@wuzumaki]

MPE does not have OPF
