Help exhaust guys!

You can get one way cheaper than what you are talking about at HF. Now, from experience, you can make dead perfect bends with that, BUT it's very time consuming. You need to choose your length of pipe, fill it completely with sand, tape up the PISS outta the ends and bend it. The sand will keep the pipe from crushing and you will get bends almost as good as a mandrel bender. But like I said, it's time consuming. I have done it like that before myself with tremendous success. The system I made with it looked as good as a TTI system.

Here's the one from HF.
