Yeah, the only way is word of mouth.One of the next things for this truck needs to be tune and delete. I'm not sure if where to buy the delete pipe yet or where to look for tuning. The Chinese sites selling junk fill the search results and people are dodgy about info on social media, probably due to avoiding attention from EPA types.
They are out there you usually just gotta have a shop that will hook you up. I've got a guy down here in Utah that does them.

They do have parts for mine. I would expect the up-pipe is optional with the EGR block off, but likely gets pulled to access things anyway? Looks like $500 in parts, plus tuner/tune to do a stockish delete.I did this for my 2008 (did not check to see if Bertha parts were there).
