I have been puttin off this job for almost a year know, I'm just waiting for the y pipe to get here from parts.com. All of the studs on my exhaust manifolds are rusted so bad that the threads will not hold the pipes in tight contact at the metal to metal seal there. I am going to try to heat them up as hot as I can without removing the manifolds from the engine. Has anyone tried this before and have you got any suggestions.
