wow! just finished my 5" exhaust
i just put my new exhaust on, 4" downpipe to a dynomax 16" bullet muffler, and then a 5" 45* elbow to a 5" chrome stack out in front of the passenger side rear, i must say this thing sounds awesome for a 7.3L. i used to have the exact same setup but with a 3.5" dp and a bigger muffler then 4" out the side, the difference in sound is amazing, id definitly recommend a 4" into 5" setup on the 7.3L, it may be to big performance wise but it certainly sounds better then flutter and thumping.
