GRiP Cat-Back Exhaust System

It features a 2.5-inch exhaust pipe diameter and culminates in dual 4.5-inch carbon fiber slip-on tips, offering a visually striking enhancement to the rear of the vehicle. A key feature of the GRiP system is its utilization of ARK Performance's signature helmholtz resonant chambers. This technology not only refines the exhaust note to be aggressive yet pleasant but also has the potential to increase airflow, leading to performance gains. The design process for each GRiP system involves careful selection of pipe diameter, resonators, bends, and muffler design to ensure a perfect fit and optimal exhaust note for the Lexus IS. This focus aims to provide enthusiasts with enhanced sound quality and refinement without sacrificing performance. Installation is designed as a straightforward bolt-on process. This specific GRiP cat-back exhaust system is designed for the 2021+ Lexus IS 250 / 300 / 350 AWD (OPTION B). Please note that the carbon fiber tips ship separately. Additionally, this exhaust system is not CARB legal and is not available for sale in California. A signed racing waiver form is also required for purchase.
