One-Touch Open and Close Switch

Some exhaust cutout systems have an activation switch that must be held down to open and close the butterfly plates. That can lead to over torqueing the butterfly shaft, which can damage the internal gears of the drive system. The Granatelli exhaust cutout systems have a smart chip-controlled, one-touch switch to open and close the butterfly plates and prevent over torqueing.

45 Degree Turndowns

Granatelli Motorsports includes 45 degree stainless steel turndowns in its kits. Using 45 degree turndowns lets you direct exhaust flow down towards the ground instead of straight out the side. This helps keep exhaust fumes out of the car.

High Flow with Extra Ground Clearance

Don’t have an oval exhaust system? The Granatelli systems can fit any 2.25 inch or larger round tube exhaust system. Since the cutouts measure just 2.25 inches tall, you now get the free flowing characteristics of three inch tubing while picking up a .75 inch of ground clearance.
