Just be careful which Locktite you use. They have various levels of strength and some of them are nearly permanent, especially on small screws. The blue stuff, labeled #242 I believe, is a good medium strength and can generally be removed. It can be softened with heat however so it might not always work well on exhaust applications depending on how hot the muffler gets. A small dab of high temperature RTV silicone is sometimes helpful to prevent exhaust bolts from coming loose too.
I was just going to mention this. A long long time ago I installed a blower on an aluminum manifold and head using locktite. Big surprise, the aluminum threads came out with the bolt when I had to tear down the engine. I no longer use it on aluminum at all but these days there are several different types and strengths.
