?? Just DPF delete & leave the CAT

I have a Smarty. If I remove my DPF and leave the CAT and run Smarty ME to delete the re-gen- Will there be issue with CAT clogging with soot? Or does soot naturally go thru CAT and catch in DPF?

Do you need the Nox Filter and Cat? I would remove them both along with the DPF and use A TBE from MBRP. This is what I have done for simplicity. I bought a 07 (MY) long bed 5. 9L exhaust system for my 08 Mega Cab. Everything bolted up with no issues, you can get either a 4" or 5" back pipe and muffler.

Jim,



I have already added turbo downpipe and want to keep the big CAT to provide a little exhaust sound reduction and not to have to add a muffler.
