Fantastic Bargain
by Bruce from Lexington Park, Maryland on June 23, 2016
With most other companies selling the manifolds and gasket sets separately, this was a nice surprise. All gaskets, hose connectors and pipe plugs included. Was out of the box and installed in minutes. Great product. Highly recommended.

Do the mounting surfaces of the exhaust ports need to be sanded clean of paint or do they ship clean?
The mounting surfaces should still seal with or without paint.
