Bring your 2012-2015 Honda Civic Si Sedan to life with the DC Sports Cat-Back Exhaust System. Designed specifically for the FB6 chassis, this exhaust upgrade boosts performance, deepens exhaust tone, and adds race-inspired style—all in one high-quality package. Whether you're hitting the track or carving through backroads, this cat-back system makes your Civic Si more responsive and more exciting to drive.
Constructed from premium T-304 stainless steel, the DC Sports Cat-Back Exhaust features 2.5” (63.5mm) mandrel-bent piping, a straight-through muffler design, and a bold 4” tip. This free-flowing setup improves exhaust flow, reduces backpressure, and unleashes hidden horsepower from your K24Z7 engine. The hand TIG-welded craftsmanship ensures excellent fitment, durability, and long-term performance under high-heat conditions.
With a deeper, more aggressive exhaust note that stays refined at cruising speeds, this system strikes the perfect balance between everyday drivability and track-ready sound. It’s the ideal performance exhaust for Civic Si owners looking to upgrade without compromise.
