Delete, what are you even talking about? That stuff has been banned and is illegal!

If you have someone who can do the tuning, have them turn off EGR actions in the tune (you won't have to do even as much as unplugging the EGR), buy your delete pipe for the DPF delete, and install it. Done. Cheapest, easiest, quickest, and most problem free way of accomplishing what you've asked for

I doubt you鈥檒l find a downpipe back exhaust for pretty much any vehicle these days.
What you could do is buy a catback straight back exhaust for something like a 2005 Dmax catback.
That鈥檚 what I did in 2008 mid-pipe for a delete pipe with a few extra pieces.

Then look for a frontpipe to bolt up to the stock frontpipe with cat, if they are even available anymore, I have 2 Diamond Eye Quiet tone frontpipes with 4 bolt flange one with aftermarket 4鈥 cat.
I put my stock cat back on because of the stinky exhaust.

All the parts and tuning is still readily available. Just need to look for it. A certain auction site will be your friend for the exhaust and the land of maple leafs will help in the tuning department.

Basically just search around and you'll find what you need with ease.

Not to jack the thread, but I bought my LMM at a auto auction wrecked. The dpf has been removed. Since the truck was running before the accident causing it to be totaled. Could one assume that if the dpf was removed then the egr is turned off. Is there a way to tell if it is? I didn't think to check for engine codes before I disassembled the truck.

Wouldn't make any sense to remove the DPF and purchase custom tuning and not have EGR turned off in the tuning. Do you have any idea who did the tuning?

No it wouldn't make any sense. I dont know who did any tuning on it the truck came from the Magnolia Texas area.

Easy way would be to just unplug the egr valve. If it has been shut off, no codes will be set and you wont get a MIL
As I was removing parts off the engine to replace the head gaskets I noticed the egr unplugged. As I removed it sure looks plugged up.

I'll second DRC on this. However, even if the stank doesnt bother you... the cat will likely help with the drone (something DRC has mentioned on this forum, and to me, before).

Leaving the cat on should tone down the drone and help with the diesel exhaust stink.
Adding a FTE resonator/muffler will help tone down the exhaust sound and drone but you鈥檒l still have that raunchy exhaust stink.

Cat and adding the FTE will make for a pleasant sounding exhaust.
Either way and even both will not alter/change the EGT鈥檚 compared to straight exhaust.
