Well my gxp already has new rims/tires and a full competition audio system. Besides the cold air intake and exhaust what are other mods to gain hp?

Please understand, we only recommend direct fit parts. However, for performance, there are many options. There are superchargers you can get, different chips for the computer. Go online and look up performance parts for your vehicle. You'll be surprised how many there are.
