Valved Catback Exhaust for Infiniti Q50

This valved exhaust system lets you switch anytime between a quiet, comfortable daily mode and a deep, aggressive performance sound. It is built from high-grade 304 stainless steel with TIG welding for durability, corrosion resistance, and a clean finish. The design is fully bolt-on, so no cutting or welding is required at most shops. It is engineered to improve exhaust flow, sharpen throttle response, and give the Q50S a stronger, sportier tone compared to the stock system, especially when the valve is open.

Fitment: Compatible with Infiniti Q50 / Q50S 3.0T models (fitment may vary by year and region; customers can confirm with exhaust photo or VIN if unsure). Designed to use factory mounting points and supports either OEM valve wiring or a remote-controlled valve setup depending on configuration.

What’s Included: Mid-pipe + rear section with valve system, mounting hardware and clamps, and either a wireless valve controller or OEM-style valve integration depending on the chosen setup.

Sound Characteristics:

• Cold Start — deep, noticeable tone with a sporty character

• Valve Open — loud, aggressive, and performance-focused with clean pops

• Valve Closed — close to OEM comfort, suitable for daily driving and late-night use
