Stripping down my new 08 F350- 6.4L Power Stroke. It has been hard to find an exhaust system for my PS and this one looks good and the first one I found with dimentions. I will let you know how it works. Doing the tranny right now then the injectors etc,

Questions and Answers
How much fabrication does this kit require? What other parts are needed to install?
View Staff Answer
Answer
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
