Description
This downpipe features German-made HJS 200 cell EURO 6 compliant trimetallic catalytic converters. Utilizing 4-inch piping from the engine side to the cat and 3-inch tubing from the cat to the rest of the exhaust, our larger catalytic converters allow for enhanced exhaust flow. The increased catalyst surface area improves exhaust gas filtering, ensuring emissions compliance without triggering a check engine light. The Fabspeed Sport Cat Downpipe is a direct bolt-on replacement for the factory M340i catalytic converter, providing significant performance improvements.
When examining the factory 12” long 700 cell ceramic core cats, we found opportunities for enhancement. The OEM Cats restrict exhaust CFM flow, limit sound, and worst of all, rob performance. Replacing the OEM cats with Fabspeed Sport Catalytic converters will net you improved performance with absolutely zero fear of a check engine light.
