Description
For over 30 years, Active Autowerke has been a trusted provider of high-quality BMW performance products. Our commitment to enhancing BMW performance through superior products has made us a go-to source for enthusiasts. Introducing our latest addition to the BMW F87 M2C, F80 M3, and F82 M4 Collection: the F8X catted downpipes with GESI G-Sport Cats. These downpipes embody our philosophy of innovation and performance.
Designed specifically for the F87 M2C, F80 M3, and F82 BMW M4, these downpipes deliver a noticeable difference in performance from the moment you hit the road. With a pair of 4" ultra-high-flow GESI catalytic converters (Gen 2 Advanced), this variant ensures there will be no Check Engine Lights (CEL) to worry about.
The GESI G-Sport Ultra High Output Catalytic Converter is constructed with full 304 stainless steel, including the substrate. These catalytic converters are EPA registered and compliant in 49 states, meeting all OBD2 regulations for vehicles manufactured in 1996 and newer. GESI's proprietary precious metal loading technology significantly reduces emissions, eliminating most "Check Engine Lights." Furthermore, these ultra-high-flow catalytic converters outperform stock converters and solve common catalytic converter issues.
With a flow capacity suitable for engines producing between 500 and 850 horsepower, the GESI UHO-Series Catalytic Converters maintain reduced back-pressure, enabling you to unleash your engine's full potential without compromising emissions. Say goodbye to Check Engine Lights and failed emissions tests!
Please note that these catalytic converters are not legal for use on vehicles registered in California due to state regulations.
It's important to mention that federal law prohibits tampering with emissions control devices. However, according to Mobile Source Enforcement Memorandum 1A, aftermarket parts can be used for repairs or replacements as long as emissions are not adversely affected. The GESI catalytic converter meets EPA standards, but not CARB regulations, regarding cell density or converter volume dimension.
