A heat shield upgrade for the stack area
The tall stainless shields create a straight-pipe style appearance around the existing muffler pipe area. The kit replaces the shields; it does not supply replacement exhaust pipes or convert the truck to a straight-pipe exhaust system.
What is included?
You receive two stainless heat shields, four clamps and mounting hardware. Exhaust stacks, muffler pipes, elbows, installation tools and lights are not included.
Before installation
Compare your current pipe diameter, top stack diameter, bracket arrangement and available clearance with the kit dimensions. The shields mount with the supplied clamps and hardware. Check alignment against the existing exhaust components before tightening the assembly, and have a qualified shop assess a modified exhaust setup.
