Close-Style Vacuum Activated Exhaust Cutout

Description

Control your vehicle’s exhaust flow and sound with this Close-Style Vacuum Activated Exhaust Cutout, engineered for performance cars, turbo builds, and custom exhaust systems. Designed to operate using engine vacuum, this valve remains closed by default and opens once vacuum pressure reaches approximately 1 BAR, giving you a clean OEM-style exhaust tone during cruising and a louder, free-flow exhaust when activated.

Available in 51mm, 63mm, 70mm, and 76mm diameters, this cutout fits a wide range of exhaust systems and offers a reliable, mechanically simple solution for adjustable exhaust output—without relying on electric motors. Built from durable, heat-resistant materials, it withstands high temperatures and continuous performance driving.

Perfect for enthusiasts who want a stealthy daily setup with the option for aggressive sound and performance when desired.
