    You can put it on and go but the question is how well and how far? Chances are you will go lean if not already. Factory set-ups are slightly on the lean side to comply with EPA. When you change pipes, the engine will breathe better making the mixture even leaner. Too lean and you can do some serious engine damage. Look over other posts in this forum...several good ones concerning this.
