Full-Race 2012-2015 Honda Civic Si Downpipe V2.0

The Full-Race 2012-2015 Honda Civic Si & Acura ILX 3.0inch Downpipe V2.0 / Header for naturally aspirated and supercharged applications. This high flowing header provides maximum gains by reducing back-pressure and allowing the motor to breath more freely. Built from stainless steel and large mandrel bent radius bends for the quickest and easiest exit of exhaust gases. The great solution for those looking for a catless or high-flow cat system (for those who are in California).

"Full-Race's new V2.0 Downpipe Revision for the 9th gen embarks on the old design and brings in a new design with a fully cast bellmouth built to reduce the cracking issue that all downpipes suffer on the 9th gen." -- HARDmotion

    Makes power

    Sounds great has a hiss but that’s to be expected with catless downpipes. MAKE SURE you get rear mount, because if you’re getting this you’re probably getting tuned and you’ll hate life until you change that mount.

    V2 is definitely better than version 1. Seems more durable and won’t crack like the other!
