CTS Turbo BMW S58 G80/G82/G87 M2/M3/M3C/M4/M4C High Flow Cats

CTS Turbo's high flow catalytic converters are purpose-built for BMW's S58-powered M2, M3 and M4 Competition models across G80, G82, G83 and G87 chassis codes. These performance cats dramatically reduce exhaust backpressure compared to restrictive factory units, unlocking sharper throttle response and improved exhaust flow for tuned applications. Engineered with high-density substrate cores, they maintain effective emissions control whilst supporting aggressive ECU calibrations. Direct bolt-in fitment ensures straightforward installation into the factory exhaust system without modification, making them ideal for dealers building complete performance packages on current-generation M cars.
