This BLOX T304 catback exhaust is built for 2006–2011 Honda Civic Si coupe 2-door applications and uses 3-inch T304 tubing. It replaces the factory back section with a full catback that follows the Civic Si coupe fitment, offering a direct-fit bolt-on solution for that model years' exhaust layout. The system is presented for customers seeking a model-specific catback with 3-inch piping and T304 tubing as specified.
