Product Details

Invidia is well-known for making performance exhaust systems that offer a noticeable improvement in sound and power. This Q300 cat-back exhaust is specifically built for the 2006-2011 Honda Civic Si 4-door model, aiming to give your Si a more aggressive exhaust note without being overly loud or droney inside the cabin.

Constructed from strong, corrosion-resistant stainless steel, this cat-back system is designed to last. The Q300 series focuses on a balance between performance and daily drivability. You can expect a deeper, more satisfying tone when you accelerate, and a smoother, more refined sound during cruising. The system replaces the factory exhaust from the catalytic converter back, which can help with exhaust flow and potentially unlock a bit more power from your Si's engine. Installation is designed to be a direct bolt-on replacement for the stock exhaust, meaning no welding or cutting is typically required.

When installing this system, it's a good idea to have a helper and some basic tools on hand. The kit includes the necessary components for the cat-back section, allowing you to upgrade your Civic Si's exhaust system for a better driving experience.
