So, recently bought my 2002 Subaru impreza wrx, love everything about it except, its an automatic -______- i couldn't find a stock manual ANYWHERE. Anyway i have some ideas i would like to do but not sure if some are worth it or if i should even make these mods. So first thing i'm doing is the exhaust system getting everything headers, up down cat, ect. Any good brands out there that i should look at? and where can i buy them. I was think on getting this exhaust system off ebay, but i'm scared it wont give the effect i want you know the deep growl but also increase HP. also a friend gave me a boost controller, I actually never herd of one so I'm not to sure what it does expect controls how PSI my turbo puts out how much is enough?? anything i should watch when using it? please help. Also looking for a performance chips what are some good ones? Please help me out, i really need it list any information you can about adding HP, which brands, and maybe some other mods that i should do. thanks

Skip the headers and boost controller. Keep your existing intake if it is stock.

See the link in my signature for more info.

Performance chips are not applicable in the modern era. Re-mapping the car does apply though. However, you do not need to do so for an exhaust on your car. See link.
