Im looking to build my own dual exhaust for my 2009 chevy 1500 5.3l crew cab short box and since i dont have a pipe bender im going to need to buy individual bends. Can someone give me a list of bends i will need and how many feet of straight piping i should buy? and also should i true dual it or just "Y" it, which muffler should i go with, and what size exhaust should i get? i want it to be really deep and growly and i dont care much about drone. thanks in advanced! Taylor Bickett UPDATE: right now i have in the shopping cart: dual in/out 2 1/2" cherry bomb extreme mufflers 2, 2 1/2" mandrel j-bends 8 feet of 2 1/2" exhaust tubing flowmaster 2 1/2" s bend combo pack 2, 4 inch exhaust tips would this be enough to true dual my pickup? or should i just go with the single in dual out?
