E46 M3 Supersprint Metallic Cat System w/ Stepped Headers 2001-2006

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: US Models have the catalysts built into the OEM exhaust manifolds. To be used with 022 044 001 header only. These are a direct replacement catalysts for Euro Models.
