Xcede E9X M3 Exhaust Exceeds Expectations!admin
Took our E92 M3 to the dyno to test our new full custom exhaust. It has our custom X-pipe which was designed & fabricated to extract maximum horsepower from the V8 engine. Added to this to make the exhaust complete was a complete back section with minimal backpressure due to custom backboxes selected after many trials & tribulations with various other sizes & designs of boxes. These backboxes yielded the lowest pressure with the maximum exhaust velocity at high rpm which resulted in record power on the dyno after a custom remap was written to take advantage of this free-flowing hardware.
