hey guys just had a few questiond b4 i go and do anything to my 06 duramax van? does anyone know what the stock size exhaust piping on my van (it looks like 3 inch to me) and since i just want very lil performance out of it but more of a tougher exhaust sound since it will be used for work should i just delete the stock muffler and replace it with just a pipe of the same size or should i get mbrp 4'' muffler? remember just want it basically stock exsept for the louder exhaust.... will this be throwing black smoke like crazy if i do so? thanks in advance

muffler or not will not change the amount of smoke you get. If you are looking to do it on the cheap I would delete the cat and muffler with straight pipe. If that's too load for you then add a muffler back in.
Diesel Particulate Filter. Thats what the LMM have on them.
ooooo and where is this filter located?

Your DPF is inline with your exhaust. In laymans terms, it's similar to the catalytic converter in a car, but for a different reason. To remove it, you need a programmer to turn off things like regeneration mode and some sensors that are programmed into your ecm.
Don't worry-your '06 van does not have this
They were installed on '07.5 and later GM diesels. Lotsofmiles is one of the redheaded stepchilds on this site with a van also! He would be a great guy to compare notes with!

Otherwise just buy the aftermarket 3". It will give you a nice exhaust note which is what you are really after the way I read it!
Myself, I have the diamond eye downpipe, and then I straight-piped it back with 4" from there. And yes it is loud!!
