BMW F80 M3 & F82 M4 S55 Equal Length Midpipe & Under Brace

Welcome to the BMW F80 M3 & F82 M4 S55 Equal length Exhaust Mid Pipe from SLN Performance. This is the best-value solution to the F8X sound problem. For years enthusiasts have wanted to find a solution to the buzzy and raspy sound these cars produce from the factory. Since these cars were released back in late 2014, we all knew there was world-class sound lying under all the rasp. SLN's mission has been to find this hidden sound and allow all F8X owners to enjoy it. It's time to make the S55 sound like it always should have.
