3-Inch Stainless Steel Cat-Back Exhaust

The Full Race Catback Exhaust is a premium 3-inch stainless steel exhaust system engineered for the 9th generation Honda Civic Si (2012-2015) and compatible with the 2013-2015 Acura ILX 2.4L. This system is designed to enhance exhaust flow and performance across naturally aspirated, supercharged, and turbocharged K24 engine builds. Constructed from durable stainless steel with 3-inch mandrel-bent tubing, this catback exhaust system reduces backpressure for improved throttle response and power gains across the RPM range. Its V-band clamp design ensures a secure, leak-free connection and simplifies installation, utilizing factory hanger locations with no cutting or welding required. All necessary gaskets and hardware are included. This exhaust is available in two specific fitment options: the FG4 2-door coupe and the FB6 4-door sedan, ensuring a precise fit for your vehicle. Proper ground clearance is maintained, preventing interference with undercarriage components and ensuring it won't scrape on driveways or speed bumps, even when the car is lowered.
