horsepower

Hey everyone I have a 97 F-250 with a 7.5 L, I really can't find any hop ups for it I want to put headers on it but i Don't want to spend 600 dollars on them. I'm going to put dual exhaust. I want easier things to put on it. Thanks for any suggestions

free flowing intake, chip, dua; exhaust with x pipe. The stock 460 headers have pretty good flow, headers would be better though.
