ISR Performance GT Dual Exhaust - 98-05 Lexus GS300

The ISR Performance GT dual exhaust for the 1998-2005 Lexus GS300 uses a true dual configuration with a muffler and tip on each side for a deep, balanced tone.

Like every ISR exhaust, it is built from T304 stainless steel with TIG welded joints and mandrel bent piping, and it bolts directly to the factory mounting points and hangers. No cutting or welding is required for installation.

Expect better exhaust flow, a modest gain in power and throttle response, and a sound that is unmistakably ISR. Contact us if you need help confirming fitment for your year and trim.

Legal only for use in competition vehicles which may never be registered, licensed, and/or used on public streets or highways; and also for use in other exempted vehicles.
