@scott135i -
I believe you have the M5 mufflers… but still have the rest of the 550 exhaust… except you cut out the center resonator and replaced with x-pipe? Is that how a stock M5 exhaust is set up?
You have stock DP's?
Could you post some driving clips from in-cabin? Flaps open and closed…please?
Thanks.
