why do u need a 3" inch dp on the stock turbo? Isnt the outlet like 2"? Anyways i dont think it is that hard to make one if you have a welder, 240hoke made mine out of 2 45* mandrel bends and he made a flange also from some metal he had. Its not a 3 inch, its a 2.5, but I am only runnin the stock turbo until june so it will do its job, so hey! in june mine will be for sale
