I just took a stub of a 3/4" muffler out of an aluminum Briggs, no lock not on it, so it took hack saw, pipe wrench, hammer, penetrating oil, cussing, two days, and a good flushing with brake parts cleaner at the end. It is always good to flush the chips from sawing out of the exhaust port with brake parts cleaner with the exhaust valve closed, (check before starting to extract. So the moral of the story is, don't make it a habit, I have two more to attack this month LOL. And yes, do as was mentioned earlier, install til hand snug, then tighten a lock nut. This will not affect you now, but give it a decade or two, if not you, somebody will thank you for not making it harder.
