Exhaust Leaks

[tinygiants]

I am experiencing exhaust leaks at my manifold to mid pipe joints.

I have a problem keeping my bolts tight. Any one else have this? I have tightened and locktighted the bolts, but they loosen back up. The nuts were not loose on the bolt (locktight). Are the bolts stretching? Any suggestions?

Another thought I had was can I use high temp silicon on the flanged joint to help keep it sealed after I solve the bolt issue?

if they are stretching you will see a "bottle cap" effect.. i think thats the correct term
I actually haven't gone back and checked my stuff but that's because i got
some new stuff on the way... how did you position then when you installed them?

Wonder if its the pressure from the FI? Nowwhat blew out his gaskets on his BB exhaust if I remember correctly.

Perhaps the tension in the bolts is heat threated out due exhaust temp ? Try high temp bolts ? Or the gasket is swimming out ? :dontknow:

I had to re-tightne mine a couple of times.. but after the third time.. that have not come loose...

Locktight won't really help on exhaust hardware. Try using star-washers or longer hardware and springs to hold things shut.
