Stock Exhaust

yep, stock mid-pipe and catback are 2.25" the whole way.

I think you can still get 2.5" mufflers welded in, but if you really want to improve and increase your sound, replace the mid-pipe with an H or X. Mufflers are OK, but don't make that big a difference. You won't be dissapointed.

In fact, with the stock catback, your stang will sound much better with an aftermarket mid-pipe.

Your sig says you got a Magnaflow catback which should be 2.5 inches. Most aftermarket catbacks are 2.5".
