BMW S63 Catless Downpipes

Unlock the full potential of your BMW S63-powered M vehicle with the CenCal Motorsport S63 Catless Downpipes. The factory catalytic converters create significant exhaust restriction, limiting turbo response and overall power. Our catless downpipes are engineered to eliminate this backpressure, allowing your turbos to spool faster, build boost more efficiently, and deliver maximum performance.

On a properly tuned BMW S63 with stock turbos, gains of up to 30 horsepower can be achieved, with even greater results on vehicles equipped with upgraded turbochargers. In addition to performance gains, these downpipes transform the exhaust note, producing a louder, more aggressive sound that matches the performance of your M car—without unwanted drone.

Precision-engineered for perfect fitment, these downpipes feature smooth mandrel bends to maximize exhaust flow and are fully compatible with both left-hand and right-hand drive vehicles.
