    Go to your local automotive store and buy a tube of exhaust sealent, take a little out of the tube, roll it in your hands into a long wire form and then apply it. Pack it in there tight and make sure its sealed,

    The best I have used is Ultra copper it is a high-temp silicone,we use it on our sleds and on our headers of our drag car and we haven't had any leaks and if you know about headers they always leak

    the orange stuff is high temp 1300c.. it works great.. the black stuff is not high temp.. the black rtv they sell at crappy tire is only good to 400c so definatly don't use that.. just check the heat rating on the package..

    why would fiberglass your exhaust pipes on..?

    also muffler cement hardens.. so if you use it.. it will crack.. silicone remains plyable..

    This is what I would use..


    Heat resistant, tough and ready to help stop exhaust leaks due to warped exhaust flanges. Orange RTV Silicone is your answer to high temperature sealing problems. Use it to reinforce exhaust gaskets during engine assembly and to reduce the danger of troublesome exhaust leaks.

    it's designed for exactly that application..
