The ISR Performance GT single axle-back exhaust is a direct-fit system for 2013–2020 Lexus IS 250, IS 300, and IS 350 rear-wheel-drive models. It replaces the factory rear exhaust section to alter tone and exhaust flow while maintaining fitment for RWD IS applications. This axle-back option provides a bolt-on route to a different exhaust character without full cat-back replacement.
