GESI Catted Race 4.5-Inch Downpipe

The Active Autowerke GESI Catted Race Downpipe is designed to significantly improve exhaust flow and performance for vehicles equipped with the B58 engine. By virtually eliminating the restrictive characteristics of the factory downpipes, it reduces radiant heat and enhances overall power output. The downpipe utilizes a 4.50" diameter, constructed from TIG-welded 304 stainless steel for robust durability. This downpipe features GESI EPA registered high flow catalyst technology, ensuring compliance with OBD2 standards (1996 and newer) while greatly reducing emissions. The construction includes a cast upper stainless steel V-Band for precise fitment and is rated to withstand up to 1500°F, reaching operational efficiency within 9 seconds of startup. Installation is straightforward, requiring no cutting or welding. It is important to note that this downpipe is not for sale or use in the state of California on any pollution-controlled vehicle, as per the California Air Resources Board. The product comes with a 5-Year / 50,000 Mile Warranty on the shell and tube ends, and a 2-year / 25,000 Mile Warranty on the catalytic core. However, the warranty will be null and void if the vehicle experiences excessive burble beyond stock, as this can physically destroy the catalytic core. This downpipe is compatible with 2024 and earlier models only.
