Is my exhaust stock or aftermarker?
I just got my 94 firebird formula last week and I was looking at the exhaust today and the catback looks like an aftermarket part because the piping to me looks like its 3".
Attached are some pictures of what it look like
Is my catback exhaust stock or aftermarket? If its aftermarket, what manufacturer is it?

Looks stock to me. Im no expert on how many TA’s came with double O tips, but overall its stock. My car has the stock rectangle tips. Different LT1 F-body cars came with different shaped exhaust tips from factory. Im not sure but I bet back in 93-02 they gave you the option to choose what kind of tips you wanted from the factory?! Check to see if you still have a cat under your passengers seat. If you do then its obviously stock exhaust.

So for it to be a full catback exhaust I would just have to replace the miffler for one that is 3" in and dual 3" out?

Yeah man everything is stock from the pictures you posted. Mufflers look stock, piping looks stock, and I bet the cat is stock. I can see it right there under the passengers side seat. Do you even know what the stock cat looks like? There is no cat in your muffler since its stock.
