PDI 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.

5″ inlet, 5″ outlet, 10″ diameter, 51″ long
