Invidia 06+ Lexus GS300 / GS350 Q300 Axle-Back Exhaust

This Invidia exhaust is built for real gains you can feel in the seat. Smooth bends and smart muffler design improve flow and throttle response while keeping the note tight and controlled. Q300 focuses on a quiet cruise with a solid, mature note under throttle; ideal if you want performance without attention at idle. Routing is optimized to cut turbulence and keep velocity up through the whole system. Quality materials and precision welding help resist heat and corrosion. The result is consistent fitment, solid hardware, and a system that performs without constant attention. Expect better response off the line, stronger pull through the midrange, and a tone that feels right for a quick street car. Bolt-on installation with standard tools in most cases.
