Product Description

The Invidia HS14LRCDR4OS Q300 is an axle-back exhaust system built for the 2015-2025 Lexus RC350 and RC200t/RC300, featuring a flat-bottom muffler design that improves high-speed aerodynamic performance while delivering a rich, deep, sporty exhaust note. Continuous internal piping combined with Advantex material creates an excellent free-flowing path with optimized back pressure, translating into genuine horsepower and torque gains over the factory system.

Constructed from SUS304 polished stainless steel with 1.5mm thick-walled, mandrel-bent piping, this system significantly reduces the risk of cracks and breaks developing over time compared to thinner aftermarket alternatives, while also cutting down on rasp and vibration. CNC-machined flanges and robot TIG welding throughout ensure a precise, durable fit at every joint.

The system exits through double-wall polished stainless steel quad tips, giving the RC's rear end a distinctive, purposeful look. Backed by Invidia's reputation built on decades of motorsport-proven exhaust engineering, this Q300 system is the correct choice for RC350/RC200t/RC300 coupe owners looking for a meaningful sound and performance upgrade before the RC's production run comes to a close.
