Review on 🚗 Dorman 674-158 Chevy/GMC Passenger Side Exhaust Manifold for Specific Models by Robert Hines

The item was in a double box and well packaged although the outer box was slightly damaged. It bolted on easily, but I had to cut some of the burr around the pair of mounting holes and mating surfaces with my head. The heat shield was slightly larger than stock and required a slight modification to allow good clearance around the spark plug boot. The kit was complete and included all the new parts needed to replace the manifold, including the gasket. It was the perfect size to replace my stock header. I thought it would require significantly more modifications to get it working, but I was happy with how little I had to do. I would buy this item again in the future.
