Catted Downpipe 2.5-Inch 304 Stainless Steel

The RV6 Performance Catted Downpipe is engineered to address the exhaust restrictions in the factory manifold of the K20C2 engine found in 2016-2021 Honda Civic models. It is constructed entirely from durable 304 stainless steel and features TIG-welded seams with argon back purging for enhanced longevity and purity. This downpipe incorporates a 300-cell high-temperature catalytic converter and a 2.5-inch outlet, which work together to significantly improve exhaust flow and reduce backpressure. The smooth, cast stainless transition was meticulously designed in 3D for precise fitment, eliminating potential gaps that could impede flow. This design is intended to provide noticeable gains in horsepower and torque, with estimates of 10-15 hp for stock K20C2 engines. Users can expect sharper throttle response and a more responsive engine feel. The RV6 Performance Catted Downpipe is available with no coating, black ceramic, or silver ceramic finishes. It includes all necessary installation hardware, such as M10 studs, flanged lock nuts, a flange bolt, an OEM-style gasket, and a wire harness. It bolts directly to the existing front pipe. The product comes with a 24-month warranty on castings and welds, though the catalytic converter itself is not covered. It is sold as a competition-use part and may not be legal for road use in all areas. This downpipe is specifically designed for the 2016-2021 Honda Civic 2.0L K20C2 sedan and coupe models. It is also noted to fit the 2022+ Honda Civic 2.0L K20C2.
