Does anybody know of a place in the SoCal area that would fabricate some custom mild steel exhaust flanges using either a water jet or a plasma cutting table? The places I've contacted so far are only interested in large orders or the price is crazy high. Any suggestions would be appreciated.

 

If you can't find a local shop, eMachineShop.com will do small orders. Draw it up in CAD in their software and get a quote. Couldn't hurt. I've used them in the past and the price has been sometimes very reasonable, sometimes not.

But, what flange are you looking for? It may already be available.
