Invidia 06-11 Honda Civic Si Sedan N1 70mm Cat-Back Exhaust w/ Titanium Tip

The 70mm mandrel-bent stainless steel piping on this Invidia N1 cat-back exhaust is a key detail for your 2006-2011 Honda Civic Si Sedan. Mandrel bending means the pipe maintains its full diameter through the bends, which helps keep exhaust gas flow smooth and unrestricted. This is a big part of why a cat-back system like this can make a noticeable difference in how your car sounds and performs.

This Invidia N1 system is built from durable stainless steel, which holds up well against corrosion and the heat cycles of exhaust systems. It's designed to bolt directly onto your Civic Si Sedan, replacing the factory muffler and exhaust piping from the catalytic converter back. The N1 series is known for its aggressive, sporty tone, and this particular system features a titanium tip for a unique look and a bit of weight savings. You'll likely notice a deeper exhaust note and potentially a slight improvement in throttle response compared to the stock setup.

When installing this cat-back exhaust, you'll want to have the necessary hangers and clamps ready. It's a direct bolt-on system, so no welding is required, making the installation more straightforward. This exhaust is a popular choice for Civic Si owners looking to give their car a more distinct sound and a sportier appearance.
