Invidia just released a Front Pipe for the 1.5L Turbo 2016+ Civic Coupe and Sedan. Just like their N1 Exhaust, the Front Pipe looks amazing, and is full stainless steel construction.

This front pipe DOES NOT replace your factory catalytic converter. Instead, it installs right after it. Essentially, this replaces the factory pipe between your catalytic converter and your main exhaust system. So, if you order this front pipe and the Invidia N1 Exhaust, you'll have a complete high performance exhaust going from the exhaust tips all the way up to your catalytic converter. This should have the effect of decreasing backpressure on the turbo and thus allowing the turbo to spool earlier as well as giving you more mid-range to top end power.

Keep in mind even though this front pipe is under our "Invidia Downpipes and Turbo Outlets" product page, it does not directly connect to the turbo (as explained above).

Except there seems to be minimal gains if any unless you upgrade the turbo according to Vit. The PRL catless did pretty much nothing except sound, he said the OEM DP and intake are more than sufficient until you go bigger turbo. And seeing I have a CVT, FlashPro will be just fine by itself, not trying to break anything.

Keep in mind that Vit's testing was with a "high octane" fuel blend that isn't knock limited like pump gas 87, 89, 91, 92 and 93 octane. Those results aren't inline with what the average owner will see. The increased efficiency of a downpipe drastically reduces knock, meaning increased power. Vit's fuel has virtually no engine knock to overcome.

I'll 2nd this.

Even on the 9th Gen Si, you can see that the factory setup is right on the edge of knocking on 91 octane, a lot due to the fact that the factory cat / downpipe is very restrictive and causes hot exhaust gases to migrate back into the engine, increasing temps and likelihood of knock. On a 9th Gen Si, running an aftermarket downpipe allows for a decent increase in timing and great power gains. I expect the same to be true with this 1.5T motor running on 91 or lower quality fuel.
