I'm guessing you have the older style pipes. (fully welded) You could sell these and get the newer style pipes from Kirkham, The new style pipes use mufflers from Burns and can be disassembled. This would make it easy to install and remove either baffles or screen cones in the pipes.
These are the new style mufflers:

Nothing lame about wanting to keep your hearing.
