Hey Guys,

I would like to build my own exaust for my 91 3/4 ton. Where should I go to get 4" Exhaust tubing that is cheap. I would like to buy 90s and 45s elbows also and custom weld it...Just like Jesse James! hehehe. What is the cost difference in Stainless and aluminized material? Is the cost justifiable? Also do you think that I need a muffler of any sort? Thanks for your help.

I got my pieces from the local exhaust shop and the 90s were about $30 a piece.
