And $50??? That's a bargain haha I may look into it more.
Yea, the BMW Performance Exhaust advertises it about 15hp gain for the N52. I highly doubt it though. That's why I am curious to see what others have achieved with their cars.

$50 is a steal lol but I'm pretty sure most reputable shops where I live will do it for closer to $100.
