DC Sports Catback Exhaust System for the 2012-2015 Civic Si (FB6), is a great way to take one of Honda's best-performing chassis and make it a bit more fun to drive.

Our catback replaces your OEM setup with larger diameter piping, a race-inspired straight-through muffler, and a 4” tip. The larger diameter 2.5” (63.5mm) piping gives your engine more room to breathe, allowing for increased performance.

Each of our mufflers is uniquely designed to drastically improve the sound of your vehicle, giving you a much deeper exhaust note while never restricting performance.

All DC Sports Exhaust Systems are made from T-304 Stainless steel that is mandrel bent and fully Tig welded by hand, to ensure proper fitment and reduce the risk of failure.
