Hmmm mis-information central.
US spec recieved the 2.5lt and is actually on par with an STi RA - which is still only the 2Lt but with twin scroll turbo setup.
Fuel ratings in the US may 'read' lower than japan but this is due to the US using a different rating system for ron content. US 93 ron is equivalent to Jap 100 ron.
And adding an exhaust to an STi (or any new age rexie) does not yeild any extra power due to the jec's compensation. The most it does is increase fuel consumption and gives you that beautiful boxer rumble.
