My silver 04 WRX is finally broken in. This car is a blast. I find that my driving habits have instantly been altered. What I am missing is a little more boost a little sooner. I guess I am about to start upgrading. Where do I begin? What will yield the best results the quickest? BOV, ECU, exhaust. I know they will all help I just need to know in what order. I need to save up $$ between each mod.

 

Yeah an up-pipe is definitely a good place to start if you want to build boost sooner and faster. A nice turbo-back (cat-back exhaust+downpipe) exhaust will also net you good gains. Finally to top it off get your ecu remapped or a UTEC or something along those lines to tune your car for the mods. You should get some very healthy power gains from these mods but I'm not sure if the exhaust will help your low end power very much. Your top end will be sweet though
