2.75" is the stock pipe size but I think you have use a 3" cut out becuase they dont come in 2.75.

You have to remove a section of your I-pipe and then have it welded in.

3". You can install it at home if you have something to cut the section of piping out of the stock exhaust and you need a welder.
