Ok so i am rebuilding this car right. well i need to replace most of the exhaust system, first of how big is too big? What is a good size? i plan on turning the RS into and RS-T so keep that in mind i don't want my car to be loud and annoying just a little bit less restricting to the car. And i don't want to sound like a Ricer when i am driving around.

For N/A applications you aren't going to want to go larger then 2.5". With the turbo, you probably want to go to at least 2.5" or 3".
