Honda 9th Gen Civic Si and Acura ILX 3″ All-Motor V2 Catted Downpipe

Note: Catted version is temporarily out of stock. 

The V2 All-Motor Downpipe is updated with an investment cast 3″ stainless steel cobra head transition.  By reducing back pressure and increasing flow, this is the highest flowing and strongest downpipe available for the 9th Gen Honda Civic Si and Acura ILX.  Designed to extract maximum power from naturally aspirated and supercharged K24Z7 engines, our high flowing design delivers significant power and torque gains throughout the power band.

Looking for the ultimate exhaust combination? Pair our All-Motor Downpipe with the Full-Race 3″ Exhaust System for additional horsepower, torque and superior tune.

2013 Civic Si Tuned by Vit

“Green graph is bone stock, Blue graph is after DP + Exhaust was installed and retuned. Fitment on the items was fantastic, no rattles and no BS. Solid power gain across the powerband too. The car’s still got the factory POS intake, I wouldn’t be surprised if it picked up 10-15 horse now with a good CAI given the exhaust is so open now.” – Vit Viper Tuning
