Akrapovich say their exhaust gives an increase of 10.5 hp. BMW CP exhaust does not raise power at all.

Yes. It's louder with a cold start. Not obnoxiously, but still louder. I actually took the jeep out this am so not to wake the kids.

Ok, I ordered the M Performance Exhaust with Titanium tips from getbmwparts. Thanks for all the help here. I will be interested to see what it sounds like.

I was debating buying from them, please let me know how good is their delivery once you receive your exhaust.

Yeah, the Akra will result in some performance gains. Sadly the CP exhaust is exactly the same as the stock exhaust except for the baffle-less mufflers and the painted tips.

The CP exhaust is extremely disappointing.

It truly is. The CP should have been stock on M5/M6s. Specially since so much of the upgrade is steering and suspension related. I feel that's how the M6 should have been from the start.

You are exactly correct. I have an Akra video to post and will do so once I figure out this file size issue.

Check this out

0:12 notice how smoke comes out of only 1 pipe on each side, do you think it's possible to remove the valves?

I bought all of the parts, even the custom floor mats from IND. I ordered OEM mirror caps and they didn't fit, they were for the 650GC. Then they were replaced by these. They match perfectly. I really like them. A tiny bit disappointed they aren't the OEM ones but they look great.

Installed the M Performance exhaust today. I am used to loud exhausts on my 458 and 12C, so I don't find it loud-- more like aggressively refined.

I think it rates higher in looks than in sound but both are good and the the build quality of Akropovic is amazing

Agreed. It's a huge upgrade from the CP exhaust but not crazy loud by any stretch. Akrapovic quality is awesome.

Post a sound clip! I'm also going through my dealer and getting the M Performance exhaust. I would love to see how it looks with the tips. Also great line up of cars!
