best cheap way to bend it is with a torch (just a regular Bernzomatic torch works fine) and a piece of pipe or a rod that fits inside the exhaust.
i used a 3' long solid tent stake that was laying around in the garage.
i heated the pipe, inserted the rod as far as it would go, bracing the pipe on the outside at the same point, so it would only bend where the rod was.
bent it out enough so the rod could slide in farther, adjusted the pipe, then bent it again.
here's mine, no kinks or flat spots;
