Were installing the industrial phat-shaft twins setup up this weekend. Mine is a 6.7 with a six speed. I have a ss magna 5 inch exhaust. If anyone else has done it, did you have a 5 inch pipe and did you have to fab a new pipe from lower turbo to the 5 inch or did industrial have a 5 inch pipe too?
I can make the 4 work, it just going to take some bending and welding.
