Hey everyone,

I have a 2009 Subaru Impreza S-GT (GH8)

-4EAT (Tiptronic)
-Protune (Dyno at 200whp)
-Full stock STI Exhaust

Everything mentioned above is exactly how I purchased the car from previous owner.

I’m interested in increasing power to maybe higher 200’s or even 300whp maximum.

Any advice or guidance on how I can achieve this power goal?

thanks in advance!
