Review on 🔧 Dorman 674-157: Top-quality Driver Side Exhaust Manifold for Chevrolet and GMC Models by Tyler Dorsey

This manifold was purchased with a Dorman 674-156 for my '93 GMC K1500 that basically needed a new rear exhaust. . I chose Dorman because of the price and the lifetime warranty. At the time of this review (12/11/15) it had been in use for 3 months. It installed well with no manifold to head gasket (meaning the manifold was done straight). Time will tell how long it will last. If there are problems, I hope Dorman will support them (I had good previous experience). If there are any problems I will come back to update. Otherwise no news is good news.
