Silverline Stack Kits feature 5", in-bed 409 stainless steel plumbing. They will fit any stack with a 5" OD base, though the included upper stack mounting kit will only fit a 5" diameter stack.
The internal design features a unique splitter plate which ensures equal exhaust flow from both stacks, resulting in a better-uality sound and improved performance.
Stack Kits come complete with all hardware and attach to any 4" diesel exhaust system. They will fit all Full size Ford, Chevy, & Dodge trucks.
Please note that this kit DOES NOT include stacks and you will need to order them separately.
