Technical Notes:

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. The PRL Motorsports High Volume 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 4.50" OD, 400 CPSI GESi G-Sport catalytic converter for the middle body. This 4.50" 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. Pair this with our 3" Front Pipe Upgrade for maximum exhaust flow and performance! 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 PRL Motorsport's Manufacturer Warranty. Insulating these components can cause heat to cause degradation of the material faster than would normally occur.

Performance Gains:

  • Increased power and exhaust flow throughout the entire powerband
  • Decreased backpressure & cooler exhaust gas temperatures

Amazing Quality & Superb Downpipe

Downpipe screams quality when you open the box. Easy to install and a vast improvement over the factory unit. Spiked up the tone of the car as well. Pair with the Front Pipe and intake upgrade and you wont be disappointed. Cant wait for the exhaust system to come out in the future.

Amazing Quality Great Investment

I’ve been thinking about making this investment since the downpipe became available and my only regret is that I didn’t buy it sooner. The throttle response is like night and day and it just feels smooth as it build speed. The install was a little time consuming but it was overall straight forward I highly recommend Watching Luis Rivera’s Video on how to install the part as it will help tremendously. Overall an amazing upgrade and a high quality product!

Great Downpipe and build quality is Top!!!

I’m almost a PRL FBO 2022 Civic Sport Touring CVT. This with the Front pipe made a great improvement in spool, power and lower heat. Can’t wait for my FMIC to complete my FBO.

This is one of the best upgrades you can possibly do to your 11th Gen Civic. This paired with the front pipe made the car wake. It’s simple to install and comes with all the hardware you need for everything to go smoothly.
