headers are a great mod but the kleeman headers arent. satisfied? im never satisfied. think of the car as a pkg not just the engine. psk, supercooler, separeted coolant, oil catch can, are just some of the engine mods. trans tune, wavetrac konis, and springs, brake upgrade all help you do what you want to do better. how deep are your pockets? that is what leads most folks! for me this is a toy. ill never get out of it what i put in it and dont care it makes me happy and cheaper than drugs!
