Product Description

The Invidia HS14LRF3SH Q300 Cat-Back Exhaust System delivers performance gains and an aggressive exhaust note for the 2015-2020 Lexus RC F equipped with the 5.0L V8 engine. The Q300 series features Invidia's specially designed flat bottom muffler that improves high-speed aerodynamics while producing a rich, deep, sporty sound without excessive volume. Inside the muffler, continuous piping design combined with Advantex sound-absorbing material creates excellent free-flow exhaust characteristics with optimized back pressure for increased horsepower and torque. The 70mm true dual mandrel-bent piping reduces exhaust restriction and turbulence throughout the system. Constructed from premium SUS304 polished stainless steel with CNC-machined cast flanges and precision robot TIG welding, this system offers outstanding durability, corrosion resistance, and a show-quality appearance. The quad oval rolled stainless steel tips with double-wall construction provide an aggressive yet refined look. Designed for direct bolt-on installation to the factory catalytic converters with all necessary gaskets and hardware included.
