Overview

The Circuit Werks rear axle-back exhaust system is designed for 2014-2024 Lexus IS models, including the IS250, IS350, and IS200T, in both RWD and AWD configurations.

It aims to provide high performance and serves as an upgrade from the stock exhaust system. The manufacturer notes that while it fits all 2014-2016+ IS models, users with 2017+ models should check their rear lower diffuser for compatibility due to potential differences.
