Invidia Q300 Ti Cat-Back Exhaust System - 06-11 Civic Si Sedan

The Invidia Q300 cat-back exhaust system for the 06-10 Honda Civic Si sounds as good as it looks. The Q300 features mandrel bent 70mm stainless steel piping and a free flowing oval style sport muffler to provide better exhaust flow for improved performance. Bolting up a Q300 to your K20Z3 will allow your Si's sonorous exhaust note to come through loud and clear when you want it to, without producing harsh or overly loud ricer overtones; the perfect choice for those who want great performance with an exhaust note that won't wake the dead.

The flat bottom shaped muffler design results in improved high speed aerodynamic performance. The muffler inside contains continuous piping design and use of Advantex material that results in an excellent free-flow exhaust with optimized back pressure, giving greater horsepower, torque gains and a rich deep sporty sound. The use of SUS304 polished stainless steel piping, Mandrel bent to shape, state of the art CNC machine made flange, Robot TIG welding and double wall polished stainless steel or Titanium rolled stainless tip, provides outstanding durability and appearance.
