BLOX Racing 06-11 Honda Civic SI Coupe 2-Door 3in T304 - Catback Exhaust

BLOX Racing is known for making well-built performance parts for import vehicles. This 3-inch cat-back exhaust system is specifically made for the 2006-2011 Honda Civic SI Coupe 2-door model. It’s designed to replace your factory exhaust from the catalytic converter back, giving your SI a more aggressive sound and improved exhaust flow.

Constructed from T304 stainless steel, this system is built to resist corrosion and handle the heat from your engine. The larger 3-inch piping diameter helps reduce backpressure compared to the stock exhaust, which can lead to a more responsive feel and a deeper, sportier exhaust note. This cat-back system is a popular choice for Civic SI owners looking to enhance both the sound and performance of their car.

When installing this cat-back exhaust, you’ll want to ensure you have the necessary hardware, as it's typically sold separately. It's a direct bolt-on replacement for the factory system, meaning no welding or cutting is required for installation, making it a straightforward upgrade for many DIYers. You can expect a noticeable change in the exhaust tone, with a richer sound under acceleration.
