Pipe bender

Those benders are not made for exhaust and will not do the job. Regardless of what you read on the internet.

You're right, conduit benders are not made for exhaust pipe. You're wrong when you say they won't work. We usually bend 3/4 and 1 inch by hand but with 1 1/2 and 2 inch we use this. It's bent some exhaust pipe too.
