Okay, so i just bought a 05 wrx with 60k, completely stock. I looked all over the internet to see what the first thing i should do to my car seeing as how im inexperienced with subaru and everything. And i came to the conclusion that i should get the cobb stage 2 power pack which includes the accessport, turbo back exhaust and the downpipe. Now, with that being purchased would i need to buy anything else to make it all come together nicely or would that be it? Because people talk about up pipes all the time and im not sure if i'd still need one after buying the stage 2 kit. Any help would be appreciated, thanks.
