Unleash maximum flow and performance with our BMW S55 3.5" Fat Boy Catless Downpipes, engineered for the M2 Competition, M3, and M4. Featuring an oversized 3.5-inch design, these downpipes dramatically reduce backpressure, allowing your turbos to spool faster and produce increased horsepower and torque across the powerband.

Built from premium stainless steel with CNC flanges and precision TIG welds, these downpipes are made to withstand the extreme demands of high-boost applications. The addition of flex sections ensures reduced stress on your turbo system while maintaining reliability under aggressive driving conditions.

The catless setup provides an unfiltered, aggressive motorsport exhaust note, transforming your S55-powered BMW into a track-inspired machine.
