Exhaust Manifold Clamps

[rizzo20]

I apologize if someone already has posted about this, but I didn't find anything in a search. I recently purchased some exhaust manifold clamps made by Dorman. I have only installed one so far and it's made a huge difference. I have a manifold bolt broke off on all 4 corners of the engine and the exhaust tick was driving me insane! I thought about replacing all the bolts but it would be a lot of agro that I'm not looking forward too. I found the clamps on amazon for $100 for all 4.

Basically these clamps bolt to threaded holes in the heads to clamp and squeeze the exhaust manifolds against the heads. The holes are threaded from the factory and aren't used for anything else that I'm aware of. What an invention! Saves a ton of work and money! They only fit the 4.8, 5.3 and 6.0 Chevy engines. I've only installed one so far but it's so much quieter. There's no doubt that once the other 3 are installed the noise will be completely gone. Here are some pics and links.

I used one for my passenger side manifold. That was almost a year ago and it's still working great.

Sure could use those on my 4.2!

I have 15, Express 3500 vans at work. They all have a 6.0 and most of them have at least one of these clamps. They are a lifesaver!
