MR2 exhaust advice needed?

My girlfriend has an mr2 spyder 2001 model and i know she wants a new exhaust and i wanna suprise her for her birthday. She wants one that is just a single pipe that comes out in the middle of the car, and looks a bit like an exhaust of a porche boxster. Anyone know what this exhaust is and where i can get one. By the way i live in Australia. cheers
