Description
Build the exhaust path around the K24.

Full-Race V2 Downpipe | 2012-2015 Civic Si & ILX. The Full-Race V2 downpipe combines a cast bellmouth with 3-inch stainless piping for the listed Civic Si and ILX applications. The available configurations let you plan the front section of the exhaust with the rest of the build.
Why it belongs on the build
- Cast-bellmouth V2 design.
- 304 stainless steel and mandrel-bent piping.
- Listed high-flow-catalyst and straight-pipe choices.
Before you order
Confirm the selected catalyst configuration and exhaust connection. A high-flow catalytic converter alone does not establish emissions approval; review application-specific requirements and the recommended rear-mount upgrade.
Plan the rest of the setup
Related parts are sold separately. Confirm fitment and option compatibility for your build.

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.

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