Two Step Performance High Efficiency Downpipe (22+ Civic/23+ Integra/18-22 Accord 1.5T)

The High Efficiency Downpipe promotes optimal airflow with virtually no turbulence, thanks to its advanced design. It features 304 stainless steel investment cast ends, CNC pocketed for a smooth transition to a 4.5″ OD, 400 CPSI GESi G-Sport catalytic converter. This catalytic converter is formulated specifically for small displacement direct injection vehicles, ensuring optimal exhaust flow. The wide shape of the cast inlet smoothly blends the turbine outlet and wastegate gases, reducing restriction, while the cast outlet allows for a smooth taper to aftermarket and/or factory front pipes. Each kit includes gaskets, stainless hardware, and all necessary components for a seamless installation.

This downpipe increases power and exhaust flow throughout the entire powerband and decreases backpressure and cooler exhaust gas temperatures. All components are fully back-purged on-site to withstand high exhaust gas temperatures, ensuring durability and long-term performance. While the downpipe is robust, it’s important to note that any exhaust components damaged due to being coated, heat-wrapped, or otherwise insulated are not covered under the Manufacturer’s Warranty, as these treatments can accelerate material degradation. The downpipe comes with a 24-month warranty covering all welding.

Enhance your vehicle’s performance with the Two Step Performance High Efficiency Downpipe and experience the difference in power and efficiency.
