Not for the purpose of running, you will notice a difference in the smell of your exhaust though. Will smell more like an old tractor with the cat removed.

They had them on most ford diesels 95-97. the trick is wether or not there are emissions tests where you live and wether or not they mandate it. For example here I have to have one to pass, but its purely a visual test meaning if they see it, its there, thers simply nothing in it.
