Electronic exhaust cutouts from Granatelli Motor Sports allow you to electronically switch from a full exhaust system to open exhaust with the flip of a switch. The cutout body is CNC-machined from 6061 aluminum and uses stainless steel butterfly valves and shafts. Electric motors are controlled by a “smart chip,” which opens the cutouts with a single touch, and does not require the user to hold down the switch during operation. Exhaust piping is stainless steel and available in 2.5-, 3- and 4-inch diameters. The 45-degree turndowns can also be rotated 360 degrees for maximum adjustability.
