Tried those routes
Hey guys thanks for the thoughts but I have tried every parts store from where I live all the way to Denver which is 3 1/2 hours away. The only thing they could do for the 4" tubing is order an entire kit from one of the manufacturers and have it shipped to them. I just want the tubing because I want to completely remove all the DPF the cat and the muffler. A buddy of mine down here has a jig made up for my truck so I can tig weld all of the components myself.
