    from the exhaust sticky:

    What Size Are The Parts Of My Exhaust?
    Y-pipe- 3.8L = 3" / 3.4L = 2.5"
    Catalytic Converter - 3.8L= 3" in / 2.25" out / 3.4L = 2.5" in / 2.25" out
    S-pipe - entirely 2.25"
    I-pipe - entirely 2.25"
    Over-Axel pipe - entirely 2.25"
    V8's have 2.5" Exhaust
