98 Grand Am GT Exhaust

I was wondering if anyone in here has replaced the stock dual mufflers on thier 96-98 Grand Am GT. I have a 98 and one of the mufflers is starting to go bad and I want to replace both of them with some aftermarket. I'm not looking for a catback, I just want to replace the stock mufflers. Anyone know what the size pipe that I will need? It looks like 2".

just run straight pipes.
