thirdgen.org is where you should go for any 3rd gen questions. but anyway, go to an autoparts store, usually autozone has them. get a piece of flex pipe that matches the OD of your stock pipe. they sell around 16" pieces and full 6' lengths. i pieced together almost an entire exhaust system for a junker racecar out of flex pipe.
