Needing some mandrel bends in 4" dia. Lookin for carbon or aluminized and curious the cheapest source

Check with truck parts shops. Most truck exhaust bends are mandrel bent. Most will be aluminized. Dynaflex is one good brand, there are others.

My local diesel shop (works on semis and dumptrucks) had a 5" with 12+" legs. 22 bucks... or 7 dollars a foot for straight.

^ those guys are local to me. fairly easy to deal with. I use them for stainless over 3"

3" and under I go to GBE bending in clackamas.

If you are in a western state, try six states distributors. They predominately sell drivetrain wear components to the heavy haul and tractor industry but the also stock some 4" and 5" bends and straights.
They are also my go to for driveshaft building. 99% they nail it first try, and if there's a problem they fix it no question no hassle. But that kinda service is rare so they are always busy!
