Re: WAT SIZE BULLET MUFFLER? I disagree.
If you are using 2.5" pipe for your exhaust, get the 2.5" bullet. The 2.5" OD of the pipe will slide into the 2.5" ID of the muffler, so to speak. The 12" bullet muffler in actuality, is 16" long. The 12" is how long the muffler section is. There is a 2" collar on both sides.

Re: WAT SIZE BULLET MUFFLER? The size of a Z, Formula or Trans am is 2 3/4". The size of a SS, RA or Firehawk is 3". U are right about the 12" bullet, 2" of pipe at each end. They do not make a 2 3/4" dia so he needs to buy a 3" and get it slipped over the I pipe like I did, fits very good and does not leak if welded right.
