Why upgrade your N55 downpipe
The factory catalytic converter uses a dense 400 cell ceramic core that creates major exhaust restriction and turbulence. Evolution Racewerks replaces this with a high flow 200 cell metallic core inside a true 4 inch mandrel bent assembly. Fewer cells and a larger, smoother flow path reduce backpressure, increase exhaust gas velocity and help the turbocharger spool sooner. The result is better drivability, more power potential and a more responsive 535i or 640i.
