Long tube headers crew cab
#4
The 1/2 ton the exhaust will go to 1 pipe mid way. the 2500hd is 2 pipes. Like said above any 6.0 truck headers will fit, its do you wanna run single or dual. Headers with mid pipe that bolts on i couldn't find any made when i looked for them for my 2500hd. I had to piece mine together until i made it to the exhaust shop. Either way you go its going to take some work. There is quite a few companies that make expensive ones and cheap ones, that part is tough with mixed reviews.
Chevy Silverado/GMC Sierra 1/2 Ton 2003-06 Headers
2003-2006 Chevy/GMC 6.0L 4WD Truck Offroad Headers
Above are 2 examples how the 1500 headers will come. The 2nd set stainless works told me to buy since they don't have a direct fit.

I think most any of the Hummer H2 ones should also work fine. That is what I have..... on many I had found back when I looked they also stated they would fit on any of the 2500HD 6.0 trucks. FWIW, I bought a set of the OBX long tubes with the high flow cats on eBay and am actually very pleased with them. Are the top of the line, no but for the price they are not too bad at all.

Contacted Kooks and stainless works. They both make them. Pacesetter as well but it's a little cheaper. Purchasing the headers once I finish restoring the frame on my truck.

Speed engineering headers and exhaust on my 04 2500hd RCLB 4wd. I had to trim the ear off of the passenger side on the 4l80. Other than that it cleared my front driveshaft and all has been well. I had to switch some of my plug wires to 90 degree boots. I cooked 2 pretty quickly with boots on them
