Ok I don,t know where to post this ...

My winter beater have an exhaust leak at the manifold and down pipe flange.

I,m going to intall a new gasket but if it leak again, can I use some JB weld to fix it ?

Honestly, I never heard anyone use JB Weld on thier exhaust. Try out the gasket first.

I used it for the bung for my egt gauge. 3 years, no problems

Works fine on my radiator. Not so well when dealing with brake fluid. Dunno about exhaust work lol.

Not recommended for use on manifolds, exhaust systems, and other engine components which normally operate at temperatures above 500° F.
