depends on what u want, show or performance...but usually the majority of people get the basic I/H/E first, if u are going for a budget of 1300, i'm sure u can get all 3 and might even have a couple hundred to spend. but if u want good performance and product quality, then u might not have alot of extra cash.
dropping it over 2" inches would cost u more money. u will need a camber kit and since ur down there u might as well get new shocks, i perfer going with a complete damper kit and then get a camber kit, rather then putting stuff together. but good kits ranger over 1300 for sure. most of the time (donest apply to everybody) when u need a camber kit is when u go over 1.8-2"
intake u can get between 150-80 bucks, regular injen,aem, k&n, etc.. cold air and such, or u want more high qaulity, then there's the V2 and other names, which will cost a lil more.
exhuast, u can go with the universal muffler, which gives u sound, but doesnt do much for ur performance, but with ur price range u can do a whole catback sys. which will so a difference in ur cars perfromance, u can feel the before and after. lil more throttle response
