Dorman Products' Exhaust Manifold Clamp Repair, No. 917-107, is perfect for exhaust manifold fastener breaks on certain General Motors and Isuzu vehicles. While this process might usually require removing the cylinder head, the repair clamp can create a seal without extracting the broken stud. The repair clamp is designed to fix the exhaust manifold on the front right on vehicles without an EGR valve or on the rear left, and offers a complete repair kit with one clamp bracket and three bolts.
