I just bought the bigger one Harbor Freight sells (like 170 bucks), for exhaust work.. Haven't even taken it out of the box yet.

That's just it. They're not for exhaust pipe. They are technically for like schedule 30 and 40 pipe. If you read the reviews, some of those who've tried exhaust pipe say it crushes it. Then some say it works well.
