The ISR Performance single-exit axle-back exhaust for 1999–2005 Lexus IS300 replaces the rear section of the exhaust system with a single outlet configuration tailored to the vehicle. It is intended for direct-fit applications on supported Lexus IS300 model years to maintain proper fitment and exhaust routing without requiring major exhaust modifications.
