so i have a stock 08 e92 6speed and a guy i know wants to run me in his 335i(dct) and he says he has a tune and an intake, but a while back he mentioned getting a mid pipe. will probably end up running him after i do exhaust atleast, but what would the outcome most likely be?

I wont be going from a dig probably like a 45 roll...
