It must be the name Michael!
I made several giant holesaws using same size holesaw/tubing. The 1-1/2" went all the way thru my Speedmaster pipes by slicing the offset tubes lengthwise. It fit the outlet end of the muffler perfectly. I also made a 1-1/4" that works fine for the America's. Slicing thru the offset tube is a pain and takes patience, but can be done. I just kept removing pieces till I got the sound I wanted: turns out I pulled them all out except the tapered cone at the very front of the muffler. I also have a set of stock pipes that are ready if those black helicopters start following me again.
Mike Sr.
