im installing a whole new exhaust system and i was wondering what the stock diameter is. the gibson cat back is 2.25, wanted to know if that was any bigger than stock.

Mine was 2.25" stock, I upgraded to 2.5"

:D

Aftermarket can be the same as stock....to keep costs down...and sell at a lower price point.

Just like after market shocks can be stock length, even though you can get ones for a lift at the same price, or a little more, etc.

:D

Either.

Mine was custom, because I re-routed mine to make room for an OBA tank.
