Product Description

The REMARK RO-TSE4-DM Axle-Back Exhaust is engineered for the 2021 and newer Lexus IS300 and IS350, offering a refined upgrade that enhances both sound and aesthetics without compromising daily comfort. Constructed from premium T304 stainless steel with mandrel-bent 2.5" tubing and double-wall 4" tips, this kit provides a deeper, richer tone while maintaining a sophisticated presence.

Installation is straightforward and truly "bolt-on" - no welding or cutting is required. The system retains compatibility with the factory mid-pipe and hangers, and reuses the original donut gaskets and spring bolts. Whether you own the 4-cylinder turbo IS300 or the 3.5L V6 IS350, RWD or AWD, this exhaust delivers improved flow dynamics, subtle weight reduction, and a crisp but manageable note that transforms your drive without becoming intrusive.

Note: While the system is listed for 2021 and newer Lexus IS300/IS350 models, official documentation up to 2024 is confirmed. Fitment for 2025-model year is assumed by the manufacturer but not explicitly published - users should verify with REMARK or their dealer to confirm 2025 compatibility prior to purchase.
