Invidia 06+ Civic Si 2dr ONLY 70mm RACING Titanium Tip Cat-back Exhaust

This Invidia cat-back exhaust system is specifically for the 2-door 2006-2011 Honda Civic Si. 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 sound and a sportier appearance, especially with the titanium tip.

The system uses 70mm diameter piping, which is larger than stock. This increased diameter helps the engine breathe a bit easier, potentially leading to a slight improvement in throttle response and a deeper, more resonant exhaust note. The titanium tip is a nice touch, adding a premium look that stands out. Invidia is known for making well-built exhaust components, and this cat-back is no exception. It's constructed to handle the rigors of daily driving while providing a sound that many Civic Si owners are looking for.

When installing this, you'll want to make sure you have the necessary hardware and that all connections are sealed properly to prevent leaks. It's a direct bolt-on replacement for the factory system, meaning no welding or cutting is required for installation. This makes the job much more straightforward for a home mechanic or a shop.
