Sorry, I haven't checked this link recently. I got my aFe intake system from Gillett Diesel in Draper/Salt Lake City, Utah. They are the authorized dealer here.

My exhaust is from Jardine Pinnacle Power Exhaust in Wyoming. Came with a 3" downpipe then 4" the rest of the way. I know I shortened that in my descriptions and apparently it led to misunderstandings. From reading past posts it was obvious that 3" was as big as you could go, so I didn't see the need to express that. I just wanted to say that I replaced the system from the turbo back and not from the cat back. Sorry.
