Flo-Pro Exhausts are designed to fit all wheelbase & cab configurations unless otherwise specified.

The perfect kit if you're looking to remove your stock components and replace it with high-performance & high-flow 5" piping from your downpipe back! Just like all of Flo-Pro's Exhaust kits, it will come with all the required clamps, pre-weld contour bent hangers, and stronger flanges to help you cruise through the installation process. You'll notice fuel mileage improvement, increased torque, and you'll have a much better-sounding 6.6L!
