3-Inch Stainless Steel Catback Exhaust

The Full Race Catback Exhaust is a performance-oriented, 3-inch diameter exhaust system crafted from durable stainless steel, designed to enhance exhaust flow and sound for the 9th generation Honda Civic Si. This system utilizes V-band clamps throughout, ensuring a superior seal, easier alignment during installation, and quick removal of sections if necessary, eliminating the need for traditional slip-fit connections. Installation is straightforward with no cutting or welding required, as it bolts directly to factory hangers and includes all necessary gaskets and hardware. It is compatible with naturally aspirated, supercharged, and turbocharged K24 engines, and is specifically noted to help turbos spool faster and increase power on forced induction builds by reducing restriction and backpressure. The exhaust tone is described as deep and resonant without being excessively loud or producing an annoying drone. Fitment is available for specific models: the FG4 2-Door Coupe (2012-2015 Honda Civic Si Coupe) and the FB6 4-Door Sedan (2012-2015 Honda Civic Si Sedan). It also fits the 2013-2015 Acura ILX 2.4L, though proper fitment verification is recommended for the ILX. Customers are advised to select the correct version based on their vehicle's body style.
