FUEL EFFICIENT PERFORMANCE MUFFLERS

The Straight Flow Performance Stack Mufflers cancel out sound waves by directing them into one another causing destructive interference for a low restriction, quiet exhaust. This is the most economic-performance addition you can add to your truck. The Straight Flow Muffler will lower exhaust temperatures, to increase fuel mileage, improve throttle response, and gain up to 50 additional horsepower.
