I've been looking around for any videos of a f10 m5 with becker performance exhaust and couldnt find squat.
so i just went ahead and ordered it to make a video for you guys.
Pros:
inexpensive.
looks decent.
super deep tone.
Cons:
fitment was terrible on the slip joints.
rear section rubs on the sub frame.
Probably getting rid of it.
Here's the video, enjoy!
