    yea something like that... i wasn't sure

    I wasn't positive on this... but isn't it 2 1/4 until the exhaust then goes to 2 1/2??? So muffler inlet outlets are 2 1/2 maybe???

    Someone clarify...

    wait wait wait...i was thinking wrong.

    the regular catback is 2.25", but the mufflers themselves are 2" inlet/outlet. after the Y pipe it is down to 2".

    Forgot GPs are like that. All Imps and Montes (even dual exhaust versions) are 2.25" all the way back to the exhaust tips.
