Either MIG (I wouldn't really advise flux core there, but if budget is tight....), or TIG.
TIG has a steep learning curve. MIG is quick and easy, especially if you want to weld on a car (1 hand operation).
TIG looks beautiful (if you master it), and MIG looks messy, especially fluxcore. Fluxcore welds pretty hot, so it's easy to blow through the exhaust and therefore less suitable (do short, overlapping welds)
Stainless or iron exhaust? On stainless it's better to use tig.
But exhaustwelding isn't that easy. Often thin material, backpurge, etc
For versatility, stick or MIG is the best, but it depends on what you want.
If you want to do bodywork on cars, you need MIG with gas (you make countless short stitchwelds that you grind back. You want no heat in your panels)

This. You are not going to weld exhaust pipes with stick rod. MiG/Tig and be done with it
