Invidia 06-11+ Civic Si 4Dr ONLY 76mm RACING N1 Titanium Tip Cat-back Exhaust

Invidia is well-known for making performance exhaust systems that offer a noticeable upgrade in sound and performance. This 76mm RACING N1 cat-back exhaust system is specifically made for the 2006-2011 Honda Civic Si 4-door model. It's designed to replace the factory exhaust from the catalytic converter back, improving exhaust flow and giving your Si a more aggressive, sporty tone.

This system features a 76mm diameter piping, which is larger than stock, allowing exhaust gases to exit the engine more freely. This can lead to a slight improvement in throttle response and overall engine performance. The N1 style muffler is engineered for a deep, resonant sound that really lets the engine breathe, especially at higher RPMs. A key feature is the titanium tip, which not only looks sharp but is also lightweight and durable, adding a premium touch to the rear of your Civic Si.

When installing this cat-back system, you'll find it's designed to fit directly onto your existing exhaust hangers. While it's a bolt-on installation, it's always a good idea to have a helper and ensure you have the necessary tools, like wrenches and possibly some penetrating oil for stubborn bolts. The result is a well-built exhaust that enhances both the sound and the look of your 2006-2011 Civic Si 4-door.
