By replacing the restrictive secondary catalytic converters located in the mid-pipe section directly after the downpipes, back pressure is reduced, which effectively improves the engine’s breathing by allowing it to expel gases more quickly. This in return means faster throttle response, increased power output and a more aggressive exhaust note.

Measuring 3.5” in diameter, this direct replacement mid-pipe offers improved flow over standard and comes complete with a replacement exhaust brace and fitting kit, which will mate to original catalytic converters, aftermarket sports cats or aftermarket de-cats.

Will fit the following models:

•     BMW G80 M3 (left and right-hand drive)

•     BMW G82 M4 (left and right-hand drive)

Please note:

-     Sports cats are sold for motorsport and off road use only and may not pass a UK MOT test or police road side checks.
