Unlock the full potential of your 2017–2021 Honda Civic Si Coupe (FC3) with the ARK Performance DT-S Exhaust System, engineered for enthusiasts seeking aggressive sound, improved performance, and superior quality. Designed specifically for the FC3 Civic Si Coupe, this cat-back exhaust system optimizes exhaust flow, increases throttle response, and delivers a bold, sporty exhaust note for both street and track driving.

Crafted from premium T-304 stainless steel, the DT-S exhaust ensures long-lasting durability and corrosion resistance. With mandrel-bent piping and precision TIG welding, the system minimizes back pressure, maximizes horsepower and torque gains, and provides a perfect bolt-on fit for the FC3 platform.
