Diamond Eye 4" Stainless Muffler Replacement Kit - 04-07 Dodge Cummins - 510217

I have a 2005, Dodge Ram 2500 5.9 liter cumins. I have been interested in purchasing a muffler delete pipe from you guys. I was looking at my exhaust and it appears that it is all welded and 1 piece, the only place I can see where is bolts off is below the turbo? So how do most people install the delete? do the cut the exhaust pipe somewhere In front of the muffler? or how is it installed is my question.?? if you could get back to me I would be grateful and most likely purchase one from you.
