No, this X-pipe is 2.5". I mean you can get anything to work with some custom welding or fabrication but if your bolting mufflers/ tailpipes, they will have to be same diameter as this which again is 2.5". Hope that helps
They may make a 3" but honestly unless your making 600+ hp, not only are you losing power but it sounds like an old truck. 2.5" gives you that tight mustang sound. And I highly recommend one chambered flowmasters. That's the best set- up.
