The ISR GT single exhaust for 1999–2005 Lexus IS300 is a direct-fit single-exit exhaust system tailored to those model years. Offered as a complete replacement for the factory single-exit layout, it matches the IS300's 1999–2005 connection points to simplify installation and provide a factory-style exhaust routing without fabrication.
