welded thursh 2 chamber muffs i was looking at the back of my stockers today and i realized that my stock piping looks a bit smaller then the 2 .25 inlet / outlet to clamp on and clamping is my option am i right or wrong that a 2.25 muffler will or will not slip over the original piping after my current muffs?? "im cutting my srocker muffs off right where the muffler is and where the pipe begins.
