First, torch it evenly across the whole bent part, on both the inner and outer spots until its slightly red.
Second, take a nice pair of vice grips(yea wtf? needle nose haha) with a nice thick rag thats damp(if your worried about scratches, make sure your outside and away from anything flammable if the rag decides to catch fire), put the rag in the grips and clamp it on tightly.
Third, use your own force to bend it back into shape, if not then just bang a hammer against the vice grips, try not to break them in the process .
Forth, it should be somewhat back into shape if you do a good job, if not then haha , look below for another idea...
Take a piece of wood, place it against the exhaust, mark with a sharpie along the lines of the exhaust until you make atleast half a circle, cut out the shape with something like a bandsaw if you have. make sure there is no uneven spots, either take your exhaust off or strap the piece of wood tightly against the exhaust, and heat it up, use a hammer to bang against the dent, having your piece of wood to shape it into.
hope this helped or gave you some ideas
