Tri-Y Headers for torque?
On V8 engines, it has been shown many times to be BS. Where this myth came in I don’t know and how it still persists after many dyno tests showing it not to be true is nearly amazing.
The tri Y headers are fine for use but I see no benefit that would have me use them in a torque search for any reason what so ever.
I am not against them ether.
On a inline 6, I have no idea.
