Description
Upgrade your BMW G80 M3 and G82 M4 with Active Autowerke's advanced Active Autowerke Signature Catted Downpipes with GESI G-Sport cats. Enhance both the performance and sound of your M-car with this full exhaust system, including the mid-pipe, rear axle-back valved exhaust, and a set of GESI catted downpipes. Experience the true power of the S58 engine while enjoying an amazing sound that will make you feel like you're driving a genuine M-car again.
The BMW S58 engine, featured in the M-series vehicles, utilizes turbochargers powered by exhaust gases. However, the OEM downpipes restrict the potential of the engine. Active Autowerke's S58 downpipes for the G80 M3 and G82 M4 help unleash this potential by providing quicker exhaust gas evacuation and turbo spool. As the first step in the Active Autowerke G80 M3/M4 collection, our catted signature downpipe is designed with 3-inch diameter stainless steel piping for increased power, faster spool, and exceptional durability. We've incorporated stainless flex joints while maintaining the OEM 70mm diameter.
These downpipes come equipped with a pair of 4.5" ultra high flow GESI catalytic converters that ensure no CEL (Check Engine Light) will be triggered. The GESi G-Sport Ultra High Output Catalytic Converter features full 304 stainless steel construction, including the substrate. These catalytic converters are EPA registered and compliant in 49 states, fully OBD2 compliant, and suitable for use on 1996 and newer vehicles. Experience reduced emissions, eliminate most "Check Engine Lights," and outperform stock converters with these high flow catalytic converters.
With a rating for engines producing between 500 and 850 horsepower, the GESi UHO-Series Catalytic Converters provide a high flow capacity, allowing you to maximize your engine's horsepower 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 the state of California as a result of California Vehicle Code Section 27156 and 38391.
Active Autowerke's G80/G82 S58 Signature downpipes offer several features that make them a superior choice. They ensure NO CEL when using these downpipes, thanks to the GESI EPA registered high flow and fully OBD2 compliant design. The casted upper stainless steel V-Band ensures precise fitment, and the 4.50" diameter piping allows for maximum power output and quicker turbo spool. These downpipes withstand up to 1500 F, reaching operational efficiency within 9 seconds of startup.
Installation is hassle-free, as these downpipes easily bolt-on with no cutting or welding required. Made from TIG welded 304 stainless steel, they offer precise fitment and durability. The ultra high flow 400 cell per square inch catalyst provides optimal performance, while being EPA compliant for use on OBD2 vehicles (1996 and newer), except in California. Additionally, the 304 stainless steel substrate is furnace-braised to the mantle for outstanding durability. With Active Autowerke's 5 Year / 50,000 Mile Warranty on the catalytic converter, you can trust in the quality and reliability of these downpipes.

Mobile Source Enforcement Memorandum 1A, allows for aftermarket parts to be used in the repair or replacement of emissions control systems, provided the emissions aren't adversely affected. There is no mention or reference to cell density or converter volume dimension. The GESI catalytic converter will produce emissions that will meet or exceed the standards set by the EPA, not CARB.
