For the love of god do not use a Thrust Turbo, Cherry Bomb, or any other type of $30 AutoZone muffler. I went through 3 of them, in less than 4 months. I now have a magnaflow on the car.

As for the resonator, I would have an exhaust shop cut the resonator away from the rest of the exhaust and weld up another one. Or you could see this as being time to get a new exhaust.
