Default Muffler keeps blowin' gaskets.???

My muffler keeps blowing gaskets for some reason, I decided to bash the muffler with a hammer to make clearance from the lower mounting studs ( I know it's not the right way to do it) I will not "Rube Goldberg" any more mufflers or other parts, Modify; yes---- bash with hammers NO... anyway I have cut the muffler off the pipe and installed a shorter muffler (small eng muffler from Ace hdwe) worked ok and acutally made the eng quieter but the exhaust "note" was a little more "piercing"... decided to install the original muffler via copper spacer and there's no tension on the pipe but it blew the gasket after a few minutes, during which time the engine actually ran better .. smoother, more power.. can anyone tell me where to get a muffler/pipe setup that I won't have to "fiddle" with?... I'm gettin' tired of this *&^($#@ muffler issue...

You may want to use a file and make sure your flange on the header pipe is nice and flat.
Do the same to the jug after you remove the studs.

It could also be clogged up w/ rust or ??? & have too much back pressure...
