    While changing my rear brakes today, I came across this. Is this on every GTP? Im trying to think back on my last one but I cant recall if this was there or not. It is just before the Y to the muffs.




    03 GTP...Its got pulleys and stuff.

    Hmm. I knew the rest of the exhaust was different. It goes from the cat to a 3" pipe that runs back to the Y.

    So, whats the point of it? I thought cutouts would be closer to the motor.

    That's with the blocker plate off?, how's it sound cruising/wot?
    It's deff a cut out (as everyone else has said), but looks to be about $5 worth of metal as compared to the motorized one that usually are near the down pipe. If its not effecting anything, id leave it, and take it off for $hits and giggles
