I have done 2 trucks now with the dynomax manifold kit from summit. Its a 2 1/4 pipe kit and comes with all clamps and hangars required you just have to buy the mufflers. I did the thrush welded Flowmaster knock offs for the first one then the second one I went with Flowmasters and I had maybe 250 total into the system. The only other thing you would need is the manifold donuts, if you still have factory manifolds. The best way is to mock it up using the clamps then drop it down and weld it up I personally dont like the clamps but they will work. The kit comes with instructions and the pipes are numbered so its a no brainer.
