Question Just bought an 05 STI

Just traded in my Evo 8 for a newer STI and was wondering what the easiest and cheapest way was to get an extra 50 or so hp out of it. I've heard just exhaust and remap can bump as much as 60+ on STI's but also this is my daily driver and I don't want to void out my warrentee by doing stuff subaru doesn't support.
As I am new to the subaru tuning any advice from someone who's been doing this a while would be appriciated.

I recently purchased and 05 STI and through searching i found openecu, tactrix, and enginuity to be the most economical way to tune. There are tunes that can be downloaded for free that do exactly what you are asking. I am not sure about the warranty issues but i belive it depends on the situation, the local tech rep, and SOA.
