Default Lmm/lml Cab and Chasis delete

What is everyone using for exhaust kits/delete pipes on lmm and lml cab and chassis trucks? Have a guy wants me to put 5” on his lml c&c but doesn’t look like theirs enough room at the most rear fuel tank/frame rail

I pull the factory exhaust cut the end off of cat and dpf remove catalyst’s and then weld it back together on all my lml cab chassis’s. Works great and has a nice quiet rumble too it, definitely more involved than just welding in a delete pipe though. I have a 13 cab chassis I did that way and prefer the sound of the gutted factory exhaust.
