Race Flow - E46 M3 High Flow Catalytic Converters

Purchase Race Flow - E46 M3 High Flow Catalytic Converters

The Race Flow High Flow Race Cats are an excellent addition to the street tuned E46 M3.
As so many mods have no effect, or even LOSE power on the E46 M3, we are always looking to deliver proven upgrades that deliver real, repeatable results. Increases that offer gains across the board and are a good value to the customer.

This high-flow center section using Random Tech brand cats is made entirely from Mandrel Bent 304 Stainless Steel and guaranteed to never rust. Fitment is great and power delivery is improved in both low-end torque and high RPM horsepower. The power gains that every M3 owner and VAC customer are seeking are now available... all while keeping emissions equipment in-tact.

We feel that this section combined with headers is THE BEST way to add serious measurable bolt-on power in the double digits to the E46 M3 while truly staying 49-state emissions compliant! Gains along with headers are typically between 15-25 WHP!

VAC Tech Notes:
-Should be used in conjunction with proper ECU Software.
-We highly recommend the use of Aftermarket headers like the Jet Hot or Agency Power along with this high flow cat section.
-O2 Sensor wires are to be extended at time of install.
