Upgrade your BMW B46 turbo engine with the Evolution Racewerks Sports Series 4" High Flow Catted Downpipe. Specifically designed for all U.S. spec 2016+ 230i, 330i, 430i, 530i, X3 30i, X4 30i, Z4 30i/20i models, this high-performance downpipe replaces the restrictive factory catalytic converter to unleash more power and improve overall engine performance. With a 200 cell metallic catalytic converter, this downpipe improves exhaust flow, reduces backpressure, and enhances turbo spool times, resulting in faster throttle response and increased horsepower.
Crafted from 100% stainless steel and precision CNC-machined components, the Sports Series downpipe provides exceptional durability and superior exhaust flow. With mandrel-bent piping and TIG welding, this downpipe ensures long-lasting performance while maintaining factory fitment with either OEM or aftermarket exhaust systems. Plus, the optional ceramic thermal coating keeps heat in the exhaust for lower underhood temperatures and better exhaust gas velocity.
