I think most exhaust shops would be equipped to do it. From talking to FenFab (who installed mine), you need to drop the subframe slightly, which supposedly gives direct access to the bolts. Making it easy to get on/off. All of this requires a lift, which most of us don't have in our garage. That being said, guys have done it in there driveways/ramps. A shop shouldnt charge you more than a few hours labor.
