The standard stack length is 36” long, which brings the stacks up to level with the cab or approximately 2” over the cab. Both 48” and 60” stacks are also available if you want your stacks to be much higher than the cab, or if you are doing a custom install and need longer stacks to accommodate your plans. The stack Installation kit adds approximately 10” of length to the stacks because of the T-Pipe mounted in the bed. There is only one hole that needs to be cut in the bed, which is for the T-Pipe. All the piping in the kit is commercial grade aluminized steel. All clamps are heavy duty and Zinc coated for durability. The kit piping transitions from 4” to 5” and all piping above the bed is 5”. Complete 5” kits are available for 5” exhausts. For optimal performance, the ideal ehaust size for diesel trucks is 4” except for trucks making extreme horsepower.
