Heatshield Products Stack Sack™ is designed to keep unwanted objects and water out of your race diesel engine’s exhaust while not in use. The Stack Sack™ is made from our HP Felt™ material, allowing you to cover stacks as soon as your vehicle has been turned off. This exhaust stack heat shield is also soft enough that it won’t scratch chrome or other finishes.


HP Felt™ is capable of withstanding continuous 1,800 degrees F. The adjustable hook-and-loop fastener strap gives a snug fit while being towed down the highway to your next race. Our exhaust heat shields are a must for any pro diesel drag racer!
