My local muffler shop. My brother used to work there about twenty years ago. My brother dug through their card catalog and pulled out a grubby old card that was titled 50-55 chevy truck. He used their equipment, reading the card, and bent up the pipe for me. It was funny because the shop owner, my brothers former boss, said that it's been years since anyone there used a bending card to make an exhaust pipe, and the couple employees there had no clue how to read the cards. Looks like another art is falling by the way side.
