Review on Dorman 674-551 Exhaust Manifold with Built-in Catalytic Converter (Not CARB Compliant), Black by Ricardo Anderson

This is my first time buying a CAT so I don't know if the internals are made of the right materials to skip emissions (the reason I bought it). The construction of the product is dense, durable steel and looks well polished and finished. All flange holes are in good condition. The upper and lower assembly are separate parts and did NOT come with connecting bolts as shown in the picture (original on my machine is a single assembly). Top flange gasket NOT included. The bottom flange bolts were also NOT supplied with the product so I'll have to shop around and look for those items myself. Since this is my only car I will most likely have trouble getting around until this part is properly installed. The parts supplied WITH THE PRODUCT must ONLY be the PARTS shown in the photo. Don't fool the buyer.
