E46 M3 Supersprint Metallic Cat

 

The U.S. 2001-2006 (E46) M3 exhaust system consists of 4 components: the headers (with integrated catalytic converters), section 1 resonator, section 2 resonator, and muffler. This item would be a section 1 replacement. These are perfect if you installed performance headers (no catalytic converters) but still need cats installed to pass emissions. 

 

High horse power performance applications require the durability and free flow characteristics of metallic racing catalytic converters. Turning up the power or using you car on the track will quickly melt down and damage your O.E. ceramic catalytic converter. Each racing converter is manufactured to racing specifications utilizing a high heat resistant metallic core. The reduced cell count from the O.E. 400 C.P.S.I. to a high flow 200 C.P.S.I. makes the Supersprint racing converters the most free flowing on the market today. All components are 100% stainless steel, and all tubing is mandrel bent to assure you the highest flow volume.

Note: For M3 (2000-2006), US Models have the catalysts built into the OEM exhaust manifolds / headers. This item should be used with Supersprint 022 043 901 or 022 044 901 Headers. This item is a direct replacement catalysts for Euro Model M3's which have no catalytic converters integrated into the factory headers.
