PRL Motorsports 10th Gen Civic 1.5T High Volume Testing

[PRL Motorsports]

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 High Volume Downpipe assemblies.

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=πr2 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

Pre-orders are now live with an expected fulfillment date of December 15th, 2021
(Please note that the pictures below are of the 11th Gen Civic HVDP Assembly. The 10th Gen HVDP will appear a bit different due to chassis differences)

I wondering, have any SI owners decided to upgrade and replace their PRL street downpipe (if you have it) with this version?
Do you have any sound clips of this DP?
I'm stuck between the 2 DP's you guys offer especially since you have the sale going lol.
I would be pairing it with the frontpipe on a stock exhaust

Have these started shipping yet?

according to their website, it says estimated ship date is 12/31 now

Ah, thank you. Should have checked right at the source to begin with.

Here's an update from the Type R thread @LBP

 

[LBP]

Thanks. No big rush on my end, it'll be a while before I could install it anyway!

I ordered mine. Can’t wait for it.

 

[Los1391]

Looks like all DPs will be shipping out early January according to their IG comments.

 

[Los1391]

Looks like some CTR owners received their DP's today.
can't wait!

 

[LBP]

1.5T HVDP estimated ship date is now January 12th.

 

[Los1391]

1.5T HVDP estimated ship date is now January 12th.

I guess everything is still backed up.
Hoping I get tracking soon.

 

[Crough]

Interested to see some numbers. I'm running the RV6 catted downpipe. If it's significant, I may sell and upgrade.

 

[LBP]

Another (minor) delay

 

[Los1391]

Messaged PRL through chat on their website and apparently mine ships out tomorrow or Monday!
Can’t wait
