Research and testing has shown that a downpipe upgrade is one of the most effective modifications to perform when looking to increase efficiency out of Honda's 1.5L turbo engine. Our High Efficiency downpipe upgrade promotes optimal airflow with virtually no turbulence throughout the body of the downpipe.
Our design utilizes 304 stainless steel investment cast ends, CNC pocketed for a smooth transition to a 4.5" OD, 400 CPSI GESi G-Sport catalytic converter for the middle body. This 4.5" OD catalytic converter was formulated for small displacement direct injection vehicles and offers optimal exhaust flow. All components are fully back-purged on site to withstand high exhaust gas temperatures. The wide shape of the cast inlet smoothly blends the turbine outlet and wastegate gases to reduce restriction, while the cast outlet allows smooth taper to aftermarket and/or factory front pipe. All kits will include gaskets, stainless hardware, and components needed for a seamless installation.
Exhaust components that may become damaged over time from being coated, heat wrapped or otherwise insulated in some capacity are not covered under the Manufacturer's Warranty. Insulating these components can cause heat to cause degradation of the material faster than would normally occur.

Best purchase you can make for the 11th gen Si
Best place to buy parts! Fantastic shipping turnaround!
I am very pleased with this DP. Not only is it EPA compliant but it is also the only DP that will not throw a CEL. Sounds great in combination with my PRL FP and Remark exhaust. I can definitely feel the power difference!
Excellent fit and finish. Noticeable gains and best of all no CEL!
