The ECU will adapt to this modification. We installed our catted version with no problems and are still currently driving the car around with no tune.

All factory mounting points are retained/used aside from the heatshield that we decided not to use because not to use this. Our cat design/shape varies from the factory unit and have not seen a need to incorporate a heatshield in our design.

No additional hardware is required, we made use of factory o2 sensors. All hardware needed to install such as gaskets, nuts, bolts, etc are included.

As of now fuel economy with our catted piece is comparible to the factory unit. We will post final numbers when we finish testing our second version cat.

We are working to make sure our catted downpipe keeps CELs off. If there are no CELs thrown cars will pass emissions/inspections.

Installation can be done with a jack and jack-stands. The book calls for right around a 3-hour install, which is pretty close to what it took us. The install is pretty straight forward, but we will try to get an install vid or writeup posted upon release! Please note that like most downpipe installs, customers do risk breaking/damaging studs/nuts coming from the turbine housing due to the heat that is produced.

The second cat version will be what ships with preorders?

What kind of impact does the catted version have on the MPG?

I would imagine better fuel economy if you drive conservatively. You have freed up power saving you from lugging the car in the low end.

Correct. Pics to come this week, results to come shortly thereafter.

Boy, am I glad to see @VitViper and @PRL Motorsports on these forums (I'm a former 86 owner, Joeprelude on FT86Club)...

For those that are questioning on getting this mod, They did wonders with the FRS/BRZ turbo systems they made, so I'd trust them on this one.

I am really considering doing the pre-order once my tax returns come in and results from the v2 catted show no CEL.

Thank you for those kind words and support! :wave:

what's the current details on pre-ordering?

PRL Motorsports said:
Retail will be $624.99 for the combo, catted version will be an additional $125. A 50% (off retail) deposit of $312.49 or $374.99 (depending on which version you'd like) can be PayPal'd to [email protected] or called in with a CC at 724-325-6300. The remaining amount will be charged with shipping and the appropriate discount tier before shipping. Please PM us, give us a call or drop us an email with your full name, address, phone number and email for contact so we can put the information on file. We will give 10% off 9 pre-orders, 15% off if there are 10-19 pre-orders, and 20% off if there are over 20. All pre-orders will also receive free stock exhaust adapters.

As much as we would like to see this assembly purchased together for maximum performance and optimal price point, we have listed the down pipe and front pipe for sale separately after popular request. To follow typical PRL suit, the downpipe and front pipe are available for 10% off intro pricing, but will not be affected by the pre-order, meaning that the names of purchasers will not be added to the combo pre-order and pricing on individual downpipes/front pipes will not see over 10% discount. Pre-order customers are still eligible for 15%-20% discount.

Downpipe $414.99/$539.99 Retail: http://prlmotorsports.com/civicxdownpipe.aspx#.WKHtX1MrKUk

Front Pipe $224.99 Retail: http://prlmotorsports.com/civicxfrontpipe.aspx#.WKHtf1MrKUk

Is there a video of how it sounds other than the one on the dyno?

We will do our best to get sound clips next week!

Vit finally has some 87 octane results with our catless combo.

Vit Tuned Results

"...When I tuned the car stock on 87 octane bone stock, I targetted 18.4psi and the boost level stayed very close to target boost. To try and give us 1:1 results at the same boost

Honda Civic 10th gen PRL Motorsports Front Pipe Pre-Order 1.5T Civic X boost_comparison-300x117

level, I actually had to target 17.5psi to get the same boost level I had before installing the downpipe. You can see this in the side by side comparison in the image to the left. I forgot to get this dyno comparison off the dyno computer before I left the shop, but keeping boost the same we saw 8-9whp on the top end and 10-20wtq gained. Keep in mind this is over our “stock tuned” 87 octane test — so we’d already worked on the timing map and fueling a bit as well. You’ll also note as we put load on the car before starting the pull — the turbo was already making almost 2psi more than before the downpipe — this will come into play later.

What does this mean to YOU? If you’re running the same tune with a freer flowing downpipe you will artificially increase the boost level a bit...

The PRL items, as always, are quality pieces. Very well done items and fitment on our car was like a glove. No rattles, no rubbing. If you don’t have a lift the install will be a bit more entertaining. On my lift it took about 2 hours to get the stock items off and this one installed. The studs in the turbo can be interesting — PRL broke theirs. I managed to get mine off without any breakage or stripping with the use of some magic lube.

So What About The Toon?
Note: blue is HP, yellow is TORQUE, orange is BOOST.

So let’s try to give it a bit more boost and see what happens? Increased the boost level about 1psi (don’t want to go crazy with 87 octane) after adjusting the timing map and such — and the results were nice. 20whp and 30-32wtq gained.

Torque came in sooner too, right? Of course — if we didn’t have the “ramp” based boost control it would of come in even sooner, but we got maybe a 200-300 rpm improvement because the turbo just wants to GOOOO with the free flowing downpipe, even if the ecu doesn’t want to let it! Peak torque however — was still the same spot. This should never really change as long as the load & ramp rate of the pull is consistent (not all dynos can control this — and certainly load will vary on the street).

Honda Civic 10th gen PRL Motorsports Front Pipe Pre-Order 1.5T Civic X dp_try_more_boost-300x166

But hey, let’s try to give it a little bit more. In the dashed line we increased boost a bit more (with a few other changes), and as you can see the gains were marginal — a bit more torque, but top end HP actually suffered a bit. We’re now at the limits of the fuel and I was starting to see the knock limit approaching very rapidly — don’t want to run here long term at all for reliability’s sake. But hey, overall we still saw 5-8wtq more which amounted to 35-40wtq through the mid range and we still picked up 20wtq up top.

...Expect to see diminishing returns in how much HP you can make with better fuel — on 93 expect maybe 8-10whp more with this downpipe. Of course more torque as well...

Vs Bone Stone?
Don’t really need an explanation I think?

Yeah after speaking with Vit he thinks the catless version is my best route.

I just ordered the catless. Why is it a better route?
