Here's mine. Not an ideal setup (I'm sure it costs HP)... but it sounds good, which was all I was going for. I never close the cutouts and it is not too loud, no drone at any RPM using the Dinan mufflers.



I think I am going to change out the stock resonator for an Xpipe and then have the cutouts as a dump like bcredliner. I HATE not having my exhaust come out of some sort of tip, but I would like a bit more volume at times so having the cutouts after the X-pipe as dumps would accomplish that. And maybe then I'd actually use the cutouts every now and then.

Here's what it sounds like currently:

X5 exhausts

The grey 4.4 N62 is running Corsa mufflers.

Dinan exhaust w/ cutouts

I have long since fixed the exhaust leak shown in the video.
