Granatelli Motor Sport's Exhaust Cutout Systems offer automotive enthusiasts a gateway to enhanced performance and an exhilarating exhaust note. In this article, we will delve into the importance of exhaust cutouts and provide a step-by-step guide on how to install both the weld-in style and the slip-fit style of Granatelli Motor Sport Exhaust Cutout Systems. 
 

 

An exhaust cutout serves as a valuable addition to your vehicle's exhaust system, offering several benefits: 

 

1. Performance Enhancement: By incorporating an exhaust cutout, you gain the ability to bypass restrictive sections of the exhaust system, allowing for improved exhaust flow. This results in reduced backpressure, enhanced engine breathing, and increased horsepower and torque. 

 

2. Customizable Sound Profile: An exhaust cutout allows you to adjust the sound profile of your vehicle's exhaust, giving you the freedom to switch between a mellow and street-legal tone and a throaty, aggressive roar with the flick of a switch. 

 

3. Track Versatility: For track enthusiasts, an exhaust cutout system provides the flexibility to meet sound restrictions at various racing events. By opening or closing the cutout, you can easily comply with noise regulations without compromising performance. 

 

Step 1: Preparation: 

 

Ensure the vehicle is safely lifted and secured. Measure the exhaust pipe diameter at the desired installation location. For the weld-in style, you will need access to a welding machine. 

 

Step 2: Marking and Cutting: 

 

Using a measuring tape, mark the desired location for the cutout on the exhaust pipe. Ensure proper clearance from nearby components. With precision, cut out the marked section using a reciprocating saw or angle grinder. For the weld in design you will need a minimum of 10" of straight pipe. 

 

Step 3: Welding: 

 

Prepare the cutout by removing any burrs or debris. Align the cutout with the opening and tack weld it into place. Double-check the alignment before completing the welding process. Weld around the entire perimeter of the cutout to create a secure and leak-free connection. 

 

 

Step 4: Wiring: 

 

Connect the wiring harness provided with the Granatelli Motor Sport Exhaust Cutout Kit. Follow the manufacturer's instructions to wire the cutout to a power source and the control switch. Insulate and protect the wiring connections using electrical tape or heat shrink tubing. 

Step 1: Preparation: 

 

Ensure the vehicle is safely lifted and secured. Measure the exhaust pipe diameter at the desired installation location. The slip-fit style cutout does not require welding, making it a more straightforward installation process. 

 

 

Step 2: Marking and Cutting: 

 

Using a measuring tape, mark the desired location for the cutout on the exhaust pipe. Ensure proper clearance from nearby components. With precision, cut out the marked section using a reciprocating saw or angle grinder. For the Slip Fit Design you will need a minimum of 12" of straight pipe.

 

 

Step 3: Slip-Fit Installation: 

 

Slide the slip-fit style cutout over the cut section of the exhaust pipe. Ensure a snug fit. Secure the cutout using the provided clamps or fasteners. Double-check the alignment and tighten the clamps to prevent any leaks. 

 

 

Step 4: Wiring: 

 

Connect the wiring harness provided with the Granatelli Motor Sport Exhaust Cutout Kit. Follow the manufacturer's instructions to wire the cutout to a power source and the control switch. Insulate and protect the wiring connections using electrical tape or heat shrink tubing. 

 

 

Conclusion: 

 

Granatelli Motor Sport Exhaust Cutout Systems provide an avenue to unlock the full potential of your vehicle's performance while allowing you to customize the sound to suit your preferences.
