Two Step Performance High Efficiency Down Pipe (17+ Civic Type R/23+ Integra Type S/Accord 2.0T)

Constructed from 304 stainless steel, this downpipe features investment cast ends and a CNC-machined transition for smooth airflow with virtually no turbulence. The broad inlet design blends the turbine outlet and wastegate gases for lower backpressure, while the cast outlet is compatible with factory and most aftermarket front pipes, ensuring easy integration without additional adapters. Fully back-purged to withstand high exhaust temperatures, this downpipe offers durability and performance, especially when paired with a PTP blanket for additional thermal control.

Every kit includes essential hardware for a smooth installation: gaskets, stainless steel hardware, heat-shield standoffs, and an O2 sensor harness extension for select models. This uncoated downpipe promises lower exhaust gas temperatures, enhanced power throughout the rev range, and an optimized exhaust system. Please note, however, that insulating this downpipe may reduce its longevity, as such applications are not covered by the manufacturer’s warranty.
