Ordered manifolds and gaskets as a set and only received one manifold? Not what I expected at all!

A bit thicker then the OEM. Gonna need at least 1 1/2 inch bolts. The elbows are plastic. Works great otherwise! Great customer service!!!

Great looking parts, true bolt on without any modifications or problems. Seller is awesome to deal with, and shipping was extremely fast. Also ordered the risers from him. Everything came with bolts and gaskets, no trips to the store. Note: you do have to get manifold bolts, I went with stainless this time.
