If your truck is a C10 with rear coil springs and a panhard bar, you will more than likely need to go to a good muffler shop and have it custom made to fit properly. There is a lot of complicated bends to get around that rear-end set-up. I have a guy here that does a lot of custom bending and put mine together without wasting one piece of pipe. Next time I'm going to get it done in stainless steel. I've got 2 1/2" pipe with Flowmaster 50's. I wish I had gone with the 40's though, all of that pipe quiets it down too much unless you are really getting on it. Well, that's my 2 cents,
Scott
