The Granatelli 2.5 Inch Electronic Exhaust Cutout is engineered to give drivers complete control over exhaust sound and performance on demand. Designed for 2.5-inch exhaust systems, this electronic cutout allows you to instantly switch from quiet, street-friendly operation to unrestricted exhaust flow for maximum performance and aggressive sound.
When closed, exhaust gases flow through the mufflers for normal driving. When opened, the cutout diverts exhaust directly out of the system, reducing backpressure and allowing the engine to breathe freely. This results in improved throttle response, increased horsepower potential, and a raw exhaust note that’s perfect for track use or spirited driving.
The high-torque electric motor and precision-machined valve assembly are built to perform under extreme exhaust temperatures and vibration. Whether on a daily driver or a high-performance build, this cutout delivers consistent, reliable operation.
Constructed with durable, corrosion-resistant materials, the Granatelli 2.5 Inch Electronic Exhaust Cutout is designed to withstand harsh underbody conditions. Weather-sealed electronics protect the motor from moisture and debris, ensuring long-term reliability.
This cutout is compatible with naturally aspirated, turbocharged, and supercharged vehicles and integrates easily into most 2.5-inch exhaust systems. It can be operated via a dash-mounted switch or paired with an optional wireless controller for added convenience.
Backed by Granatelli Motor Sports’ performance engineering and racing heritage, the Granatelli 2.5 Inch Electronic Exhaust Cutout (SKU: 307525C) delivers the perfect balance of convenience, durability, and performance—giving you full control over your exhaust system whenever you want it.
