I have a 2002 GT convertible.
I would like to get 2 Flowmaster 40 series mufflers, but I have NO clue on what size or inlet/outlet specs.

Can anyone help?

Also, does anyone have any comments on the 40 series?

2.25" if you're using the stock tubing. i think* its offset inlet/outlet, but not 100% sure.

He's right, but you can get 2.5" welded in if you can get the muffler shop to do it.

I think Summit Racing actually lists what Flowmaster part # to use on our Mustangs. They are all the same inside so just go with whatever size pipe you have. I believe its 2 1/4." You can always crawl underneath n check. Ive had the 40's on a few cars n trucks. I like 'em. No complaints unless your cruise RPM is in the drone zone. Ive run the Super 40's on a couple rides now. They are just a tad quieter inside but deeper n I like that!!

OEM is 2.25", but most people opt for the 2.5" mufflers and any muffler shop can weld these right in. You want offset/offset inlet/outlet.
