The fabrication required is not usually needed on the kit, but actually the application in which you’re installing the stacks. All stack piping, heavy gauge band clamps, and your stainless unistrap clamps (to secure the stacks) are included to install the stack kit. Generally there is very little fabrication required. *Stacks are sold separately
