Stock exhaust diameter size?

I have 2002 tacoma (prerunner if that makes a difference).
Im ordering flowmaster 10s. And im getting mixed responses people saying 2.25" and 2.5"? Anyone 100% sure what the stock exhaust size is?
Thanks!

 

It would help if you tell people what engine you have.

 

3.4l v6

 

I just unbolted before the cats. It measures 2.25" exactly

 

Cool that will help people that have that question in the future...mine a 4 cyl...so I am no help at all

 

No one uses search, so probably not.

 

So on my 6 cylinder can I bolt 3in were exhaust connect to manifold... It looks like 3 into 2.5 caty

 

Wrong sub forum

that being said, it might be possible to measure with cheap harbor freight calipers

I believe V6 is common to have a somewhat smaller pipes up front that underneath the truck both merge into a larger single section, at least 4.0 which I’ve heard might be stock 2” pipes into one 3”. Not sure about 5VZFE.
