This decat downpipe was developed for BMW models with the N63N, N63R, S63N and S63R engines and replaces the restrictive OEM catalytic converters for maximum exhaust gas flow. With a diameter of 76 mm (3”) back pressure is significantly reduced, resulting in faster turbo spooling, more power and a more aggressive exhaust note when tuned.
The downpipes are made of high-quality stainless steel and designed for clean, durable installation. Suitable for performance builds where maximum flow and reliability are required.
