Manual benders will work if you have the right dies but they are most come with
pipe dies and if you use them on exhaust tubing it will crush the tube. If you have
the correct dies they will work. The dies are the most expensive part of the bender.
Thank you sir. I really appreciate this information. This answers a big question I had, which was: can I get started with a cheapo bender for the occasional job. Answer: no, they don’t have the right dies
