Invidia [06-11 Civic Si Sedan] Q300 Cat-Back Exhaust - Stainless Tip

The Invidia Q300 Cat-Back Exhaust for the 2006-2011 Honda Civic Si Sedan (FA5) is the refined, daily-friendly way to unlock better flow and a richer exhaust note. A single polished stainless steel tip exits a large-volume Q300 muffler engineered for a deep, smooth tone without excessive cabin drone. Built from 304 stainless steel with 70mm mandrel-bent piping and minimal bends for low turbulence, the system improves throttle response, horsepower, and torque while hangers welded onto the stock locations make installation a direct bolt-on.
