The Granatelli 3.0 Inch Electronic Exhaust Cutout is designed for drivers who demand instant control over exhaust flow, sound, and performance. Engineered specifically for 3.0-inch exhaust systems, this electronic cutout allows you to transition seamlessly from quiet street driving to full, unrestricted exhaust flow at the push of a button.
When closed, exhaust gases are routed through the mufflers for normal cruising. 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 an aggressive exhaust note ideal for track use or spirited driving.
Featuring a high-torque electric motor and a precision-machined valve assembly, the Granatelli 3.0 Inch Electronic Exhaust Cutout is built to perform reliably under extreme exhaust temperatures, vibration, and demanding driving conditions.
Constructed from durable, corrosion-resistant materials, this electronic exhaust cutout is engineered for long-term durability in harsh underbody environments. Weather-sealed electronics protect the motor from moisture and debris, ensuring consistent operation whether on a daily driver or a high-performance build.
Compatible with naturally aspirated, turbocharged, and supercharged vehicles, the 3.0-inch cutout integrates easily into most aftermarket exhaust systems. Operation can be controlled via a dash-mounted switch or paired with an optional wireless controller for added convenience.
Backed by Granatelli Motor Sports’ performance-driven engineering and racing heritage, the Granatelli 3.0 Inch Electronic Exhaust Cutout (SKU: 307530C) delivers total exhaust control, durability, and performance for enthusiasts who want the best of both worlds—quiet when needed and wide open when it counts.
