So I can hear it in the morning or after pu has been sitting and engine cools off. Is this an exhaust manifold bolt issue? I think I saw a thread about this a while back on this site. Is this an issue the dealer will take care of or is it a DIY. Which bolt is the one that breaks on the hemi ?

 

take it to the dealer , should be covered under lifetime power train warranty

 

This just happened to me. I took it in and they had to replace a cylinder head as the stud broke off and they couldn't get it out.

 

If it is loud upon cold start and then gets quieter as it warms up it is likely a broken exhaust manifold stud/bolt. As noted, it should be covered under warranty unless you have a ton of miles.

Hello everyone I have a 2012 ram st that has the same problem loud upon cold start and then gets quieter as it warms up. Now could this be my problem also broken bolts? I bought my truck used with 19K miles Now it has 25K what is the warranty on these trucks? this is my first Hemi. Also I installed a S&B CAI would this void my warranty. If i still Have warranty lol

 

It should be under warranty yet. Bring it to the dealer and have them check it. I have no idea whether the CAI will be a problem.
