Dam turned out to be an intreasting thread !
Comparing planes, lawnmowers and chainsaws to loud pipes that some dipstick paid bought to make something louder. I don't buy that. Those things are loud but thay came that way.
The old Dodge I use for work had glass packs on it when I got it. I live in town and go to work early. The first thing I did with it was take it to the muffler shop. The muffler shops main buisness is putting loud pipes on! I'm one of the few that took them off.
The whole thing is like a smoker that thinks he (or she) should be able to blow smoke anywhere. Smoke um if you got them but don't blow it my way. Heck I chew but I don't spit on the guy next to me.
