Header-Back Exhaust Systems

Will this fit a 2001 Ford Excursion with the 7.3?

Wanted a 4inch but they only offered a 5 inch. But it wasnt to hard to install only issue was that from the down pipe there is a adapter from the 4inch downpipe to 5 inch where it ends up is right at the transmission support member so securing and tightening that adapter pipe is difficult might have to weld it to prevent it from moving.
