    exhaust? is there a too big

    i have been reading up about exhaust for the a turbo car, most sources state that for turbo the bigger the exhaust the better. Is there no limit to this logic?
    But now to my questiion: I have 2.5 inch piping until the downpipe, which there after is ALL stock, should i continue with 2.5 or should i go up to 3 in?

    how much horsepower are you running... IIRC 2.5 is good up to 200-250ish (someone correct me if I am wrong) horses. Upgradeing before you hit that isnt good for much at all.

      yeah.. up to 250hp 2.5 piping is the way to go..
      There was a thread not long ago about the exhaust diameters on turbo cars.. look for it.

          From what I'm told by the guys overseas, a GTX should have a 2.5 inch exhaust and a GTR aka T3 or larger should run a 3 inch exhaust.
          1991 Mazda 323 GTR Sedan
          MODS:
          GTR motor swap, F&R Familia strut bars, MX-3 Rear Lower strut tie bar, GTX front bumper, GTX grill, EDM headlights & corners, EDM 323 rear garnish, EDM spoiler, EGT sideskirts, MX-3 seats, GTX steering wheel, EGT glass sunroof, WRX hood scoop (functional!!), and other things that take too much space to list.....
          TO DO LIST:
          EDM/JDM rear bumper
          EDM/JDM power folding mirrors
          Repaint car

            I'll be running a 3" exhaust from the downpipe to the Apexi N1 muffler.
