Same thing that happens to head bolts the aluminum expands and stretches the bolts.

It don't matter how you get there, if you don't know where your going.

Just a little reminder; if your engine is running too lean it will run hot causing things to expand alot more than normal. This will loosen things that were tight.

If you have excessive vibration in your start shaft or clutch area it will cause loosening as well.

I use blue locktight on my exhaust bolts and the locktight is still intact upon removal. If your engine runs too hot it will defeat the locktight.

if your running a YS91, make sure your bolts are not too long and bottoming out...mine were about 1-2 threads too long. so it would seem tight, but the pipe would come off every flight.

this is what i have been doing for a couple years now, and seems to be working great for me.

i clean the bolts so they have no oil on them. i also wash my nuts...

metal on metal is great as long as both surfaces are perfectly flat, but i still smear on a thin layer of high temp silicon gasket maker.

i also smear a bit of the silicon on the bolts themselves. you could also use a lock tite high temp thread sealer. this prevents oil from penetrating the threads, and loosening the bolts.

then, where possible, i double nut the bolts.

Metal to metal.- skip the gasket.
locktide will eventually eat your pipe's treads when you disassembly it after a crash.

lock tite shouldnt be used anyways. it is not rated for the temps the pipe operates at. it actually softens and will make things worse.

think about it...the common method to remove something with lock tite is to heat it up...
