Default El Cheapo exhaust mod...

Hi Guys

I took the bikes out today and my old 50cc ht exhasut gasket failed. Only half the gasket blew out right at the very bottom of the exhaust manifold.

It was a little noisier but a whole lot more powerful. Im going to replace the gasket tomorrow but it got me thinking , If i drilled a small hole in the exhaust manifold and cut a thread in it. I could stick a bolt in the hole when i want it quiet and unscrew it when im in the bush and get a big performance gain.

Is it that easy or am i forgeting something?
