November 6, 2012I have a 7.3L in my F150. I want to put a new downpipe on it but I`m not sure if I should go with 3" or 4". Are both pipes gonna have the same inlet size off of the turbo? Thanks

December 18, 2012they should have the same size where it meets the turbo, I have a 4 inch on mine and love it.
