  • ATP exhaust manifolds transport burnt exhaust gasses from the engine to the exhaust system. Over time exhaust manifolds can crack or warp releasing hot exhaust gas into the engine compartment. These gases can find their way into the passenger cabin creating a dangerous situation. The best way to repair the broken manifold is to replace it with a new one. ATP Exhaust manifolds are designed to fit and function like the original part restoring the exhaust system by eliminating the dangerous leaks.

Question From Maddog95 on fix for exhaust manifold leaks

If I'm going to give practical advice, it is going to be this. Do not waste your time and money having someone else take out your exhaust manifold and cylinder head just remove broken off or stuck bolts in your exhaust manifold. I solely rely on using KAP exhaust manifold bolt repair kits. I own a shop and for those who do not want to put them in themselves, I'll install them for them. It is way easier on me and way cheaper on the customer. Incase you were wondering, they should fit all gm truck, suv, g-series vans, hummers, etc with many different motor sizes. All it takes is a phone call.

Response From Discretesignals Top Rated Answer

Interesting. Had to pull the driver's head on a 6.0L Yukon because it had an exhaust leak and two broken bolts. Sent the head to the machine shop because we were not going to free drill them out and possibly destroy the head in the process. Come to find out the machine shop had one heck of a time getting them out because the factory bolts are encapsulated. This looks like a great fix for a DIY on a pinch.

Response From nickwarner

Neat product. I can see the appeal for those who do not have or aren't real good with a welder.
