Upgrade your Lexus IS250, IS300, or IS350 with a CSZ valved catback exhaust system designed for a cleaner rear layout and adjustable sound control based on the selected setup. This exhaust system is made for Lexus owners who want a more finished rear-end exhaust package.

Before ordering, confirm your Lexus model year, engine, chassis, rear bumper style, exhaust layout, valve setup, and local exhaust rules. Professional installation is recommended to verify fitment, valve operation, and secure mounting.
