Fabspeed Motorsports now has performance products available for the E46 M3 automobile which are a direct replacement for the OEM products designed to relieve the most restrictive points in the exhaust system.
We have Sport Headers available which feature Fabspeed's signature 3-into-1 high velocity merge collector for improved exhaust scavenging and major increase in power. Constructed from 14-16 gauge T304 stainless steel, these headers replace the OEM manifolds which contain the primary catalytic converters for a more exotic car sound and an increase of 24HP/24ft-lbs of torque. $1,095





Fabspeed also has a Modular 200 cell Sportcat/Catbypass Pipe available to replace the OEM secondary catalytic converters. We offer this section as a "modular" unit so if you run our Sport Headers you can utilize the 200 cell Sportcat section as primary sportcats with no C.E.L. and is safe for emissions. If you run the factory headers which contain the primary catalytic converters, you can opt for the catbypass section to improve power and sound. This modular section is constructed from T304 stainless steel and complies with 50 state emissions and inspections testing. $1,895 (Modular System) $525 (Catbypass Only)
