Performance exhaust for 2011 M3

[edu09]

I own a 2011 M3 CV and want to install a performance exhaust, I know BMW just release a new exhaust that suposelt increases 10 hp to the engine but it is quite expensive (over $4300)
Any suggestions as of which would be the best choice for a M3 performance exhaust?
Thanks

They have a quoted hp gain for the performance exhaust??

The largest increases in HP/Tq I've seen in my brief research stint have been the Gintani exhaust system. Its what I'm leading towards unless Megan Racing gets a x-pipe out to go with their incredibly inexpensive exhaust (<$500).

Anybody that says you will get significant power increase from an axel back exhaust is selling you snake oil. You will only see significant power increases if you go HFC or catless. Otherwise, acknowledge axel back exhausts for what they are -- change in sound. As such, buy the one that sounds the best to you.

Although BMW only states a weight reduction of 20 lbs by installing this exhaust, I was told by a technician at BMW that a gain of 10 hp will come with this performance exhaust, I dont know if this will be a credible statement

With few exceptions, you'll find that people on these forums are much better informed about our cars than anyone working at a BMW dealership. In this case, this exhaust will net you approximately 0 HP.
