Been there destroyed that
Ok I got the 4" turbo back mbrp that I ordered from a vendor I wont name. I opend the box and the turbo down pipe is only 31/2" Now my question is, is this right??? I called the place I ordered it from and asked him if a 4" turbo back is suppose to have a 31/2" down pipe, he told me they all did because you cant get anything bigger than that on a ford!!!!! Now I may be retarded but Im pretty sure ive read several threads on here where you guys have talked about bigger down pipes than that. So is a 31/2 down pipe all that mbrp sales with their kits???? What should i do just put it on and forget about it or make them get me a 4" like I ordered???? Its my opinion that if you advertise a 4" turbo back it should be 4" all the way from the turbo.......
