Catback V-Band Exhaust System

The Full-Race 06-11 Honda Civic Si Catback V-Band Exhaust System is a 3-inch, 76mm exhaust engineered to deliver top power gains for the 8th generation Honda Civic, whether naturally aspirated, boosted, or supercharged. The system features V-band flanges for easy and precise installation. This exhaust system fits all 2006-2011 2-door coupe and 4-door sedan Honda Civic Si models. It includes an optional pipe to connect to either an OEM catalytic converter or 3-inch headers/downpipes. For optimal performance, especially with turbo applications, a race header extension is suggested. The design provides ample clearance for various suspension components and chassis elements, and it's noted to decrease spool-up time and increase overall power on turbo applications. During installation, ensure the adapter pipe faces downwards to avoid interference with the underbody. When pairing with headers, a stock setup utilizes an OEM header with a PLM V2 or 2.25-inch outlet, while a race header setup is designed for PLM V1, Skunk2 Header, or other 2.5-inch outlet headers. For boosted applications, it is compatible with R18 Civics using 3-inch turbo downpipes. Professional installation is recommended, with one reviewer noting a $80 cost for a seamless experience.
