If the M Performance comes out with a cat back for the 328i (currently it is axle back only) I will probably go with that assuming a $1200 or so price tag. Also interested in what Akrapovic comes out with though I'm sure it will be pricey. I voted for the Rogue. The combination of price for cat back and results makes it a good choice IMO. Waiting for JV to post more video/pics when he gets it back to make up my mind. Either way I am waiting until at least this summer to do the exhaust.
