I was looking into getting an m3 style rear bumper for my e90 and I was curious as to if anyone has attempted to adjust the pipe positions to fit the rear bumper. In all of the pictures I have seen, the people using these bumpers have somehow modified the exhaust to exit towards the middle of the bumper like in the actual m3 e90. My question is who has done this and about how much did it cost to do this exhaust modification?

Thanks in advance!
