Semi Truck Exhaust Manifold with Integrated Catalytic Converters

The first thing I noticed when I unboxed this manifold was how well made it is. The welds are clean and the stainless steel feels durable. The gaskets included were great quality. Once installed, no more rattling or check engine light, and the car feels more responsive.

Was a pretty easy install. Mounts fine to the block and to my other Magnaflow cat down below. Has bolt mounts for the old cover. Performs great! Only thing I thought was odd is the lack of several mounting spots. Reusing the old heat cover only has two bolts where stock uses 4. And the only way it's held on to the engine is to the block itself where stock has two more bolts down towards the lower end on the block. Plus there's a secondary heat shield that goes around the stock cat where on this there are no bolt holes for that shield at all. Really this isn't necessarily a problem but it would have felt better if I could have at least mounted the whole thing to the engine with those two lower bolts and the top heat shield a bit better.
