Exhaust Diameter

[Sharkster]

Anyone know what the stock diameter is on the 01 Cobra.
Not sure if its 2.25 or 2.50 im looking at some new flowmasters and dont want to get the wrong ones.

2 1/4 110% sure if its the stock pipes.

FYI
2005 mustang is the first and only mustang with 2 1/2 pipes from the factory.

I'd just get the whole catback...no more crush bends and it'll flow better than the stock piping...
