its going to give you quite a bit of power, those pro chamber mids give more than a normal H or x does. I had one on my 95Gt back when they first came out and to tell you the truth I didnt care for it :-\ I went from a off road H to it and the pro chamber killed the sound. It was almost stock sounding in my opinion. But on the good side I swear I could feel a S-O-T-P power gain. Any way if your going from all stock to this, you should be happy.
