nope on the stg 1or 2. The stock WRX is in a great class and I don't want to change itwow thats big even for autox, are you gonna go stage 1 or 2 anytime soon? Did you feel any gains from the muffler deletes?
Reportedly, the nameless adds about 10 Hp but I can't say that I feel it. Restriction is non existent now though
