    the pipe size. most exhaust shops carry 2.25, 2.5, 3.0, 3.5 and 4.0. Not many carry 2.75 and if they do, you have to by the whole length. If you know somewhere that does, then great! You're lucky!

    It may be, but on my TA (non-ws6) its 2.75". The outlets may be 2.5" but for the Ipipe, I dont believe so.
