So i am not sure i am getting my question out correctly. I did some further research and what i am trying to do is make Pipe or Exhaust Pie Cuts to make bends or radius for my exhaust routing. Why on earth I could not come up with the words "Pie Cut" is beyond me, LOL. I do though like the idea on how to make a straight cut on pipe with the poster board... i will be using this idea.
Funny how a simple thing like this is there and yet I never thought or knew of this.

I always use worm-gear/radiator-hose clamps for marking straight/360° cut lines on tubing. They come in all kinds of sizes & are adjustable as needed. We all usually have several used ones lying around as well.

My recommendation for partially cutting through then tipping over & repeating the process on tubing yields a pie-cut. Once your pipe/tube is 'tipped' over enough, you can repeat the process on the next piece w/the same number of cuts to return back to straight.
