You have stock DP's?

Could you post some driving clips from in-cabin? Flaps open and closed…please?

Thanks.
Yes. M5 mufflers and custom x-pipe replacing the center muffler. All else stock including downpipes.

It's the same setup that the full m5 exhaust has except the m5 downpipes are slightly different, it's 3" throughout with no crush points and it's x-pipe is not as well flowing based on some pictures I've seen of the cross section.

In 2-3 weeks when warmer I'll get cold start clips, warm start clips, and clips while driving both inside and outside the car with flaps each open and closed. Thanks Go Pro HD.
