Is there any place in town that stocks mandrel bent pipe for sale? U bends, 90 degrees, and 45 degrees? I can buy the stuff off JC Whitney, but I would rather get it locally.

 

Try napa. They have an exhaust catalogue with some of that stuff. I got a 90 degree 3" pipe from them. Pretty sure they had other bends. I you want straight pipe try a small muffler shop. Mad Hatter sold me a 5ft section pretty cheap.

 

I got a bunch of 2.5" J bends...a little rusty but they will do the job. I will sell them cheaper.
