I installed the X-pipe with the Roush Axle-backs, sounds great. I jacked the car up in the garage to do it. The biggest issue I had was trying to fit under the car in a way that I could achieve leverage for using the Sawzall. If you use the jack-method, use care as not to cut into the floorboard. Also, I would recommend NOT using an impact (it is not recommended anyway). My 20V Dewalt "Impact" did the trick. The engine side clamps gave a little challenge to get off, but not much. The resonator is heavier than you'd expect, but not bad for the way you have to remove it.
