Valved Stainless Steel Catback Exhaust System for Infiniti Q50S 3.7L

Upgrade the sound and performance of your Infiniti Q50S 3.7L with this Valved Stainless Steel Catback Exhaust System, engineered to deliver aggressive performance acoustics with driver‑controlled sound adjustment.

Designed specifically for the 3.7L V6 platform, this system improves exhaust flow by reducing factory backpressure, helping enhance throttle response and mid‑range acceleration. The integrated valved muffler system allows you to switch between a refined daily‑driving tone and a louder, race‑inspired exhaust note when desired.

Constructed from premium T304 stainless steel, this exhaust system offers excellent heat resistance, durability, and long‑term corrosion protection.

Precision engineered for direct bolt‑on installation using factory mounting points.
