IS300/IS350 Axle-Back, Burnt Single-Wall Tips, REMARK RO-TTE4-S

REMARK RO-TTE4-S is the axle-back configuration with burnt stainless-steel single-wall tips. The current manufacturer fitment table lists 2021–2025 Lexus IS300 turbo and 2021–2026 IS350 V6, with RWD or AWD. It does not fit 2014–2020 IS models.

This muffler-delete system includes left and right axle-back sections with 2.5-inch T304 stainless tubing and 4-inch tips. Expect a louder exhaust character than the factory mufflers.

• Burnt stainless single-wall tips; verify the exact suffix when ordering.
• Reuses factory donut gaskets, spring bolts and nuts.
• Check local sound requirements and the condition of the retained factory hardware.
