Been doing a lot of searching and reading and the general consensus seems to be to leave the cat alone. Okay, so I really want to leave it in there but I just can't stand the stink that thing creates! It doesn't smell like a diesel at all, it just reeks something awful.

Someone please tell me there's a cure for this. Oh, truck is an 06 3500.

 

Does it reek of Rottela?

 

No, it has a putrid vinegar-like smell.

 

I get that when I eat too much turnip greens.

 

Yep, that is the cat. You could tie one of those pinetree looking air-fresheners at the end of the tailpipe! Not much you can do short of the obvious, but do you really want to go there!
I love dogs, don't care too much for cats!

 

Yep, I remember that smell, before all was removed. now it smells like it should.

 

That kitty is sick better take it to the vet and dispose of it!!

Nothing that a small caliber to the head won't cure.

 

Could be from the ULSD and the cat converter. Smells like propane burning.

Speaking of which, I was behind a 2nd gen Dodge Cummins today while riding the Hog and it smelled like propane. Don't know if he had propane injection but did it stink.

Yeah, it smells like a combination of vinegar, ammonia, propane, and someone's dirty socks. Makes me nauseous. I know there's not much you can do about it and remain "legal" but I'm surprised more people don't grumble about it.

UnrulyNFS,
You're not painting a pretty picture there!

 

I'm not smelling anything at all in my 06, even on ULSD (I dont even get the "just changed the oil" smell in my 06). But then, I dont park in a garage, and I'm never outside while my truck is running, so I dont have any opportunity to really smell the exhaust.

 

Hmmm...wonder if it has anything to do with the brand of fuel I use? You don't find diesel at every gas station around here so I always go to the Chevron closest to home. Haven't tried any other brand of fuel but I can't imagine that would be the reason?

 

You could burn biodiesel and have your truck smelling like fast food

 

Just gut the cat, that way it looks like you have one but really don't...
