The factory downpipe on the 11th Gen Civic and Integra is a genuine restriction — the car has real power left on the table, and the downpipe is one of the biggest bottlenecks in the way. MAPerformance's downpipe opens that path up with larger 3" 304L stainless piping and smoother transitions that maintain exhaust gas velocity, eliminating the backpressure the factory piece is known for.

A MAPerformance-spec high-flow catalytic converter rated for 500 horsepower keeps things emissions-compliant without choking flow, and everything is hand TIG-welded at their Wrightstown, WI facility. The turbo outlet flange is CNC-machined 304L stainless, and the factory-style connection keeps installation straightforward with limited tools.
