Performance Benefits:
The factory BMW downpipe features restrictive ceramic catalytic converters that limit airflow and power output. Evolution Racewerks replaces these restrictive components with a 200-cell high-flow metallic catalytic core that drastically improves exhaust gas velocity. The result is increased horsepower, reduced turbo lag, and better throttle response across the entire RPM range.
Unlike the stock ceramic design, the metallic catalyst can endure higher temperatures, offers longer life, and provides superior resistance to heat fatigue — perfect for both street and track use.
The Evolution Racewerks Sports Series Downpipe maintains compatibility with OEM and aftermarket exhaust systems without modification. The downpipe replaces only the primary catalytic converters, allowing you to retain the secondary catalytic converters for emissions compliance or additional customization.
Construction Details:
Each downpipe is handcrafted in the USA using 304 stainless steel, mandrel-bent for optimal flow. All welds are TIG-welded in-house for precision and longevity. The V-band flange is CNC-machined from billet stainless steel for perfect fitment to the factory turbocharger. O2 sensor bungs and brackets are laser-cut and welded for OEM-style reliability.
For added performance and heat management, an optional black ceramic thermal coating is available, helping to retain exhaust heat within the pipe, improve flow velocity, reduce engine bay temperatures, and protect nearby components from heat soak.
