"H" or "X" Pipe advice Please

65Val I heard that too about finding the "hot spot". A guy told me they use those heattemp IR guns to find the hot spot as well. I agree with you 110% that an "X" pipe would flow best. No doubt about it. If I was running full out competition that would be the way to go but, I'm trying to find a economically acceptable middle ground. Ya the headers are at different angles but, those TTI are installed by the TTI instructions. The angle are no big deal and I can work with that. I was originally thinking of buying a pre-build 3" "X" pipe and working it into my system. The look very nice.
Another question, I’m not fond of welding galvanized exhaust pipe. Who is? I wire wheel off as much as I can near the weld points. But, as you know it does not take long for the weld and heated area to rust. Do you know of a spray or galvanic coating that can be applied after welding?
