nextlevelinnovations

I have an 01 Saleen S281 SC with 34kmi on it and the car is bone stock...not for long. I am already set on LT's, offroad X pipe, and Magnaflow Magnapacks. Not sure whast else would be the best decisions for me to make. So far I am assuming: 373's or 4.10's, cams, supercharger pulley, cold air intake, throttle body, MAF, changes to my fuel system etc. Any advice and suggestions will be greatly appreciated regarding mods and suggestions on sizes or specs. The car will be mainly a sunday cruiser but I refuse to stare at the rear bumper of a civic if you know what I mean! Thanks
