Valved Catback Exhaust for Lexus IS300 (2021-2025)

This valved performance exhaust system allows you to seamlessly switch between a quiet, refined daily driving tone and a loud, performance-oriented exhaust sound. Manufactured from premium 304 stainless steel with precise TIG welding for durability, heat resistance, and a clean, corrosion-free finish. The system is fully bolt-on — no cutting or welding required — ensuring easy installation at most professional shops. Designed to improve exhaust flow and throttle response, it delivers a deeper, richer tone and a sharper exhaust note compared to the stock system, especially when the valve is open.

Fitment: Compatible with 2021-2025 Lexus IS300 (may fit other IS-series depending on exhaust layout; buyers are advised to confirm with a rear exhaust photo or VIN if unsure).

What’s Included: Full mid-pipe + rear valved cat-back exhaust system, mounting hardware and clamps, and a wireless valve controller or OEM-style valve integration depending on chosen setup.

Sound Characteristics:

• Cold Start — deeper and noticeable tone that stands out from stock
• Valve Open — aggressive, sporty sound with clean pops and enhanced exhaust note
• Valve Closed — close to OEM comfort, ideal for daily driving and residential neighborhoods

Shipping: Ships directly from our partner factory. Estimated delivery time is 2–5 weeks, depending on destination and shipping method.

Warranty: If the exhaust arrives damaged or defective, we will provide replacement parts.
