Invidia 06-11+ Civic Si 2Dr ONLY 76mm RACING N1 Titanium Tip Cat-back Exhaust

This Invidia RACING N1 cat-back exhaust system is specifically for the 2006-2011 Honda Civic Si 2-door model. What you get in the box is the complete cat-back assembly, ready to bolt up behind your catalytic converter. It's designed to replace your factory exhaust from that point back, giving your Si a more aggressive tone and a distinct look, especially with the titanium tip.

The system is built with 76mm (approximately 3-inch) diameter piping, which is larger than stock. This larger diameter helps reduce back pressure, allowing your engine to breathe a bit easier. The N1 style is known for its sporty sound, and the titanium tip adds a touch of flair that stands out. Invidia is a well-known name in the performance exhaust world, and this system is a popular choice for Civic Si owners looking to enhance their car's performance and sound profile. Installation is typically a direct bolt-on process, meaning no welding or cutting is required, but you'll want to ensure all hangers and connections are properly secured for optimal performance and to prevent rattles.

When installing a performance exhaust like this, it's a good idea to check all the factory hangers and ensure they are in good condition. Sometimes, with a larger diameter pipe, you might need to adjust the routing slightly to ensure proper clearance from the chassis and drivetrain components. This cat-back system is designed to work with the factory catalytic converter, so you won't need to modify that part of your exhaust system.
