Just got off the phone with Stainless Works. The headers themselves are the same however the length/width of the collectors and connection points are different. The 5.0 has 2 1/4" exhaust. An exhaust shop could make it work, although I'm not sure that would be worth messing with.
I have SW long tube headers from my previous 2015 5.0. They look identical (to what they show as a GT350 LT header) and I'm trying to find out if anyone has run them and if so what did they gain in additional power.
