Product Description

The Invidia HS13LISG3S Q300 Axle-Back Exhaust with polished stainless steel rolled tips is a performance exhaust upgrade tailored for Lexus IS250 and IS350 V6 models. Constructed from durable SUS304 stainless steel with mandrel-bent piping and precision CNC-machined flanges, this axle-back system enhances exhaust gas flow and reduces back pressure compared to the factory exhaust. The engineered flat-bottom muffler design contributes to improved high-speed aerodynamics, while the resonated setup produces a rich, sporty tone with controlled cabin drone.

Featuring dual polished 110 mm rolled stainless steel tips, the HS13LISG3S not only upgrades the rear aesthetic but also offers corrosion resistance and robust build quality. Installation is a direct bolt-on using OEM hanger locations and included hardware, making fitment straightforward for experienced installers and performance enthusiasts alike. Designed for Lexus IS250 and IS350 V6 sedans from 2013 through 2022 where supported, this Q300 axle-back exhaust delivers enhanced throttle response, a deeper exhaust note, and a refined driving experience without sacrificing everyday comfort.
