304 Stainless Steel Catted Downpipe

The RV6 Performance Catted Downpipe is engineered to address the exhaust restrictions found in the factory manifold of the 2016-2021 Honda Civic 2.0L K20C2 engine. Unlike vehicles that can accept a traditional header, this Civic's design integrates multiple catalytic converters directly into the manifold, significantly impeding exhaust flow. RV6 Performance developed this downpipe as a direct solution, featuring a single-piece layout that replaces the restrictive factory components. Constructed from durable 304 stainless steel, this downpipe utilizes a 300-cell high-temperature catalytic converter to improve exhaust flow while maintaining emissions compliance in certain regions. The tubing is 2.5 inches in diameter, and the unit boasts a smooth cast stainless transition for optimized flow into the outlet. Every weld is meticulously TIG welded with argon back-gassing to ensure purity and longevity, preventing issues like warping or cracking that can plague lesser quality components. The downpipe bolts directly to the existing front pipe, simplifying installation. This downpipe is specifically designed for the 2016-2021 Honda Civic models equipped with the 2.0L K20C2 engine, including both sedan and coupe variants. It is also compatible with the 2022+ Honda Civic 2.0L (K20C2). The product comes with all necessary installation hardware, including studs, flanged lock nuts, a flange bolt, an OEM-style gasket, and a wire harness. Buyers can choose between three finishes: no coating, black ceramic, or silver ceramic. It is important to note that this part is sold as a competition-use part and may not be legal for road use in all areas. The catalytic converter itself is not covered under the 24-month warranty, though castings and welds are.
