i have a 05 serria denali crew cab 6.0l with a with a single down pipe off the turbo.

what diesel exhaust works in the same hanger locations on my truck??

fabing a section from the down pipe to the 4" is not a big deal

 

if fabbing the section from the dp isn't a problem, then fabbing hangers shouldn't be either and you could put it wherever you wanted, or utilize the stock hangers, right?

 

true, but i am looking for as litttle fab time as possible, just makes things easier if it just slides into place

 

Any one you get will probably have to be tweaked a bit, the HD's have more room above the crossmembers to route the pipe. The hangers are also a bit longer on the HD kits if I remember right because of the thickless of the frame. I would just grab the system of your choice and do what it takes to get it to fit. A competant shop should have no problem at all. Just don't get a rolled tip, the one I had (Aero DT4050) was like a damn megaphone and droned it's *** off. When I seperated the joint after the axle, just leting the 4" dump right there, the drone magically disapeared. I've heard others with rolled tips on big pipes that experienced the same issue.
