Long story short, I found out the car was in an accident and the dealer didn't disclose it to us (even though we asked if it's been in an accident)... Lets just say I aggressively negotiated (blackmail is so negative) for a different one. I ended up going from 33k-38k miles over the course of 4 months, then I changed to one with 5k miles AND it had AC'd seats

Will do. Denali's/Esky's have the 3.5" correct? Or is it the 3"
I was considering putting in a small muffler on the alternate opening that way I have some sort of backpressure and also not completely obnoxious
Hello. I've searched everyone and can't really find any information regarding a butterfly valve on a diesel? Is not a good idea because carbon buildup would be very fast ultimately sticking the valve one way? I just bought a 2005 3500 that I use for my personal truck as well as my tree service company I started this year. I have removed the catalatyc converter as well as the silencer ring and air baffle on the turbo. I do a lot of in town work and would like to keep the quiet disposition of the truck while going to and from jobs but I also put a lot of miles on the highway pulling very heavy loads of wood and saw chips. I think this set up would be ideal for me and my situation. Any help would be appreciated!Long story short, I found out the car was in an accident and the dealer didn't disclose it to us (even though we asked if it's been in an accident)...

aren't diesel mufflers just big straight thru pipe wrapped in packing? they don't seem to do much.
I'm not sure you'd be bypassing much noise. unless it's a Cummings. good engine but god I'm sick of listening to those things with open exhaust driving around. if so. please install and never open lol.
you probably have a 4in exhaust? any one would do, they don't make a lot of big size. most are 2.5-3in. if it got soot in it, just hit it with some brake clean from time to time. the butterfly ones seem to open faster than the slider type. a lot have a small wireless clicker to open and close. I wish they would get better at ones that looked at throttling position and rpm to open. those seem to be slow coming.
my c6 has the oem flaps, and while I have the bypass button, it's much nicer to idle around quiet and let the ecm open it when needed depending on driving. wish the aftermarket would step up.

On my roommates 14 Chevy Caprice we put Chevy SS mufflers on it we swapped the electric cut out for Vacuumed ones. Also the trick on the Pump is to get it from Autozone or O'Reilly Auto Parts they come with a lifetime warranty.

Reviving old threads is fine, especially if the the old posts are relevant to all readers. Starting new threads without context can make it harder to understand the big picture.
Also, commenting about reviving an old thread (but adding nothing to it) is just as silly as posting a question about turbo-diesel 3500 performance on a N/A board.
