HTT vs ATS- which is the better manifold?

[WUnderwood]

I am with ATS, I had mine coated, and looks great and performs nicely

The thermal coating helps to allow heat to dissipate heat faster

I don't think it allows it to dissipate heat faster, it actually insulates it so the heat stays in air tracks and insulates the metal. Trying to keep the heat in the exhaust and not allow it under the hood.

ATS casts the BD manifolds. You do have to assemble the ATS manifold but it's very simple. ATS is thicker and a much better casting, in my opinion, than the one from Hight Tech - not knocking their product. You can get ATS stuff pre-assembled and coated too.

ATS does not cast our manifolds.



Thicker is not always better, as it puts more weight on the passenger side of the head, possibly making it harder on bolts. You can use a stronger/better heat resistant material and get away with less wall thickness. Thereby saving a little cost.



Our manifold come with the proper coolant line support plate and stainless mounting bolts.



zstroken, you are correct you want to keep the heat in.
