The Invidia Q300 Exhaust System features the performance and quality you'd expect from Invidia, however it carries a quieter tone than the N1 series exhausts. This is a top-of-the-line exhaust system for the performance minded individual who wants to maintain a stealth exhaust tone quieter than typical performance exhausts.
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 tips, provides outstanding durability and appearance.
