I want to spread the word to all my fellow GM/ Chevy truck and SUV enthusiasts. There is an easier way to deal with broken exhaust manifold bolts. I used to try to drill out the broken or rusted bolts and it's just a hassle, and over half the time it doesnt even work. I would highly recommend using KAP brand exhaust manifold bolt repair kits. Quality made, affordable and a permanent fix. I wouldn't do it any other way.
