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 when paired with an ECU tuner like Hondata or KTuner. The PRL Motorsports downpipe upgrade promotes optimal airflow with virtually no turbulence throughout the body of the downpipe. V2 design allows users to retain the factory heat-shield with our full 3" (76mm) downpipe.

PRL Motorsports design utilizes 304 stainless steel investment cast ends, CNC pocketed for a smooth transition to the custom spun and coated 400-Series high flow 300 CEL catalytic converter for the middle body. This custom catalytic converter has a much higher flow rate and was designed to reach operating temperature faster than other manufacturers' catalytic converters. 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.

Pair this with PRL's 3" front pipe upgrade for maximum exhaust flow and performance! All kits will include gaskets, stainless hardware, and components needed for a seamless installation.
