BMW M3 M4 Catback Exhaust Mid Pipe F80 F82 3.5”

MTC Motorsport BMW M3 M4 Cat Back Exhaust System in 304 Stainless Steel

Our custom made cat back system for the BMW M3 and M4 measures 3.5”/89mm and is made from stainless steel.

The system fits on the car from our decat pipes or from the standard catalytic converters back to the standard back box on the car providing a much more aggressive tone without being too loud. 

The fitment is perfect and all you will require to fit is some 63mm internal diameter sleeves and clamps to connect the system to the back box as in the pictures. Also you may require some new bolts as the standard ones don’t always come out.

This will fit to any standard system, and will also fit with all decat pipes as they fit to the standard system.
