But bill, I have depended on my pipes to save me. I carry around a 13mm box end wrench and a 12mm socket wrench just in case my life might be in peril.. I was attacked one time by a guy with a knife. I quickly unbolted my pipe. So now I had a big stiff hollow tube versus his knife. Because I have no baffles, I yelled through my pipe at the attacker "HEY YOU, DONT YOU STICK ME WITH THAT KNIFE" If I would have had the baffles in he might not have been scared and he wouldn't have run away.
