Scorpion Exhausts BMW M2, M3 & M4

Cat-back and GPF-back exhaust systems replace the rearmost section of the exhaust and set the overall tailpipe style and tone. Downpipes, front crossover pipes and mid pipes address the section between the turbochargers or headers and the rear system, and are offered in catless and high-flow sports cat forms depending on the model. Supporting parts in the range include secondary catless pipes, resonator delete pipes, centre section and catalyst replacements, rear mufflers and exhaust tunnel braces.

Match the chassis code shown in the product title to your car before ordering. Common identifiers in this collection include E36 and E46 for the earlier M3, E90 and E92 for the V8 M3, F80 M3 with F82 coupe and F83 convertible M4, F87 for the M2 and M2 Competition (F87N), and G80, G81 Touring, G82 and G87 for the current generation. Some listings also specify Competition or xDrive variants, pipe diameters such as 70mm, 76mm or 89.9mm, and whether the car is fitted with a GPF, so compare these details with your build and local regulations.

Fitting typically calls for a hoist or secure vehicle support, penetrating fluid, new gaskets or clamps where supplied, and standard metric hand tools. Catless and sports cat pipework may affect exhaust emissions, engine management behaviour and noise output, so consider the implications for road use in your state. Installation by a professional workshop is recommended.

Will a cat-back system fit my M4 convertible? Check the chassis code in the title - F83 denotes the convertible, while F82 is the coupe.

What is the difference between a catless and a sports cat downpipe? A catless pipe removes the catalytic converter entirely, while a sports cat retains a high-flow catalyst.

Are these parts road legal in Australia? Emissions and noise rules vary by state and territory, so confirm compliance with your local authority before fitting.
