11th Gen Honda Civic PRL Motorsports 11th Gen Civic 1.5T Front Pipe Development 218060995_199075688899622_1301718681992330279_n


Over the past few weeks our engineers have used our 3D scan data to develop a downpipe and front pipe upgrade for the 2022 Honda Civic 1.5L Turbo. We were able to put together a street downpipe with high-flow catalytic converter, utilizing cast 304 stainless steel upper and lower pieces that allow customers to retain use of the factory heat-shield. The community can expect some big news regarding this downpipe coming soon.

A 3D printed front pipe has been fitted to the vehicle to test fit clearance and desired fitment. Now that fitment has passed inspection, we are test fitting a production-level prototype utilizing our new mandrel bent 3.00″ 16 gauge 304 stainless steel tubing, premium interlocking flex bellow section and 304 stainless steel CNC machined flanges.

We hope to have this all into production within the next few weeks, stay tuned for more details!

PRL Motorsports is proud to announce our direct partnership with G-Sport Emissions Systems Powered by GESi. We have been working behind the scenes for many, many months, in an effort to change the downpipe game for the Honda community. Recently, the stars have aligned, allowing us to implement GESi/G-Sport’s 400 CPSI, catalytic converter in our new 11th Gen Honda Civic 1.5L Turbo High Volume Downpipe assembly.

What is CPSI?

  • CPSI, or Cells Per Square Inch, are used to measure how much catalyst material is used in a catalyst substrate. The lower the CPSI rating, the less restrictive the catalytic converter. For example, a catless downpipe would have a 0 CPSI rating. However, a lower CPSI rating also means a catalyst with low effectiveness. A higher CPSI means a more effective catalyst. A 200 CPSI cat will have holes 2x the size of a 400 CPSI cat.
What are the benefits of this GESi/G-Sport catalytic converter?

  • All of our PRL Motorsports downpipe assemblies for the Honda 1.5L Turbo will utilize a 4.50” OD 400 CPSI (500-850 HP calculated by GESi/G-Sport) catalyst body, in comparison to our previously used 4.00” OD 300 CPSI (350-500 HP rated) catalyst body. Using to A=Ď€r2 calculate the cross sectional area of the catalyst body, we can see that a 4.00” diameter cat has a cross sectional area of 12.57 sqin and a 4.50” diameter cat has an area of 15.90 sqin, which is a 27% increase. Our new assemblies will be the highest flowing, least restrictive downpipes on the market that will not require any type of ECU calibration or tuner for installation. Because of this increased flow, we will be marketing these downpipes as “High Volume”
  • (Soon to be) EPA Approved (currently undergoing testing)
  • Top-grade materials, such as a brand new catalyst coating engineered specifically for Direct Injection applications
What does this mean for PRL’s other downpipe assemblies?

  • We will be implementing GESi/G-Sport’s catalytic converters in to these assemblies in upcoming months as well. Current supply chain issues, manufacturing lead-times and EPA testing have caused some delays, but no need to worry!
  • In case any 2.0L Turbo customers are reading this, we’ll have some more exciting news for you shortly!
Pricing will be announced shortly. However, customers can expect a notable price change from our current/previous downpipes due to the added costs of a larger, EPA-friendly, 400 CPSI catalytic converter.

The PRL Motorsports High Volume Downpipe Upgrade promotes optimal airflow with virtually no turbulence throughout the body of the downpipe. Like our standard downpipes, this will fit all factory heat shields, bracketry, components and front pipe. Our design utilizes 304 stainless steel investment cast ends, CNC pocketed for a smooth transition. 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. All kits will include premium gaskets, stainless hardware, and components needed for a seamless installation.

So these will pass smog?
Pending EPA approval (downpipe) and it's got a bigger cat so it'll probably be fine. Can't even sell to the largest economy in the US or 5th largest in the world if emissions-related bolt-ons aren't certified.

Last week, we strapped our 11th gen to the dyno to test our new front pipe. We started with completely stock baseline runs at an average temperature of 59°F and an elevation of 1160ft, and both runs were performed on the same day.

11th Gen Honda Civic PRL Motorsports 11th Gen Civic 1.5T Front Pipe Development PRL vs Stock FP.PNG


With the car completely stock, we saw a maximum horsepower of 171WHP. After just a front pipe swap, we saw a maximum horsepower of 175WHP, and as much as a 7WHP midrange increase on completely stock ECU mapping.
