Mostly I read to open up internal restrictions and make the exit hole bigger and/or more numerous. I have this nagging suspicion that while performance may improve by a seemingly haphazard approach, the mods may be far from optimized.
Will a big hole dead-center in front of the exhaust port perform the same as the same size hole coming out the side?
Will a hole hogged in top right corner perform the same as a pipe welded in same location that extends half the depth back into the muffler shell?
How does optimal exit size relate to displacement?
I dont see much information on correct way to mod a muffler to more or less optimize a muffler mod, mostly just remove screen, get out the drill. Are some methods better than others?
