No one makes a long tube header for the LS 4x4 blazer swap.
I looked around and only found shorties, which didn't interest me. They aren't worth much power over the truck manifolds, which are actually a decent flowing piece, said to be one of the best LS manifolds aside from the vette. For $500 for shorties I elected to just use the truck manifolds.

I simply made some exhaust pieces out of mandrel bends to connect the manifolds to my current exhaust system, which is a dual exhaust. I then welded in 02 bungs right after the exhaust manifolds in a convenient spot.

At some point if someone comes out with long tubes, I'll swap over.
