Product Details

Invidia is well-known for creating performance exhaust systems that balance sound, style, and performance. This Q300 Titanium Tip Cat-back Exhaust is a prime example, specifically built for the 2006-2011 Honda Civic Si Coupe. If you're looking to give your Si a more aggressive exhaust note and a distinct visual upgrade, this system is designed to do just that.

The Q300 series is engineered to offer a pleasing, deep exhaust tone without being overly loud or droney, making it a comfortable choice for daily driving. This particular version features a titanium tip, which not only looks sharp but also adds a touch of performance flair. The cat-back design means it replaces the exhaust system from the catalytic converter back, allowing for better exhaust flow compared to the stock setup. This can lead to a slight improvement in throttle response and a more satisfying sound under acceleration. The system is constructed from durable materials to ensure it holds up over time.

When installing this cat-back system, you'll be replacing the factory exhaust from the catalytic converter back. This typically involves unbolting the old system and bolting in the new one. While it's a bolt-on installation, it's always a good idea to have a helper and ensure you have the necessary tools on hand. The result is a cleaner look under the car and a sound that better matches the sporty nature of the Civic Si Coupe.
