I would also highly recommend that you just get a high-flow cat, and have a muffler shop cut out the old one, and weld in the new one. There's nothing plug and play about the cat on the Celica. The reason it will cost so much from Toyota is that it's all one pipe from the header collector to where the muffler bolts up. Technically, it'd be plug in play, but the pipe is abut 3/4 the length of your car.
