Good question, I don´t think there should be difference. The problem is that I ordered the heat insulation and was sent by mistake the not insulated. Not a big deal, I don´t track the car anywayI’ve not really looked into the Y pipes yet but will do at some point when I change the manifolds. What is the difference between yours and stock?
In any case, given the excellent quality of manufacturing, they should be better than stock.
Maybe @Airie can explain what the difference is.
