Description

Unlike restrictive factory exhaust, Granatelli Motor Sports manual exhaust cutout dual systems promote better exhaust flow, enabling vehicle exhaust gases to escape easily, facilitating more air intake, and ultimately benefitting your engine. As a result, your vehicle gains enhanced torque and horsepower, which in turn significantly improves your overall driving experience. Choose between a quality OEM sound for street use and the ability to switch to a wide-open, race-ready growl when desired. Granatelli manually controlled exhaust valves mount to most standard size exhaust piping and can be opened or closed by removing the 3-bolt block-off plate underneath the car. Systems are available in stainless steel or aluminized mild steel, choose the preferred cutouts for your vehicle's exhaust system.
