Well guys
To me it boils down to what ever woks best for the individual I have had the oppertunety to work with many different kinds of loctite products to find that they work very well and I know that I could use there product for my exhaust system with no problem, However I chose to use the hevy duty gasket material the type with metal fibers in it, I have found that when you tighten the muffler screws down the gasket forms around the edges real well and it is so tuff that it cand be removed and re install many times so that is why I use gasket material it works well for me, I do not use the stock gasket it sucks,
