I am looking for an exhaust that looks pretty much stock, but gives better performance. I found the M2 Exhaust with the twin 3" pipes, but from what i have been reading it seems pretty crappy. I'll even settle for a single tip out the back, but I don't want it to be big. Can anyone help?

 

prodrive and strommung both make axle-back exhausts which should flow a little better (+5-10hp) and look stock.
