My e92 M has been the toy that I tinker with for so long, I think it's about time the M2 gets some proper aftermarket love. Really wish I could hear one in person before committing though

I resisted for a while because I had trouble justifying something that doesn't really impact performance. I wish I had done it sooner. It brings me much joy. Treat yoself

I wasn't a Parks and Rec fan until now / maybe that vid will help convince my wife it's a good idea… lol

It's very quiet unless valves are opened manually. The system functions in Auto (BMW program) or open. The auto logic is very quiet, but you'll appreciate it on the highway. If your fob turns red and you don't notice a substantial change, then I'd say the sound control kit isn't working.

The valves are working, that's why I said at idle with the valves open it sounds crap, it just sounds rough, unlike the 1m for example, it has the DP cats and a superprint straight pipe to stock back box and it sounds awesome at all rev range.

So, to clarify; The Akra sounds amazing once you get going but I don't think with the valves open at idle it sounds good, when the valves open around 2.5k on Wot it's an amazing sound one of the best I've heard

I had Akra with and without modified midpipe. I ended up with stock midpipe and definitely prefer the sound profile of that Akra setup over stock at all rpm's.
