Yeah...I'm trying to soak in all of the above. I've got a stock exhaust manifold that someone split before I got the truck. It's been running great and sounding even better. Problem is, the new exhaust elbow added onto the manifold is starting to crack at the weld. Anyone have any ideas, short of starting all over with a stock manifold and having it split? I wanted to get my exhaust manifold jet-hot coated. I've been looking at the various custom headers available, but haven't seen a custom dual exhaust one yet that'll heat the floor of the intake manifold.
