Oem diameter of catback on THP

[gustavovon]

Guys, could some one confirm the stock diamter of the catback ? Its 2" or 2" 1/4 ? I am thing about to go with 3" instead of 2 1/2.

The number 57mm is ringing some bells, so that would be 2.25", but that is only from my memory of someone else's memory of the actual figure.

Thanks, bens ! I heard that too, but want to confirm

I'm not sure if it's a constant diameter as I've heard a few numbers floating around. I know having measured the pipe by the resonator when I had it chopped out that it was only around 51mm at that point. I was quite surprised as I always presumed it would be 57mm.
