yes. 02+ WRX/STI CBE's will fit on 06+ 2.5i
CBE = Cat Back Exhaust!

I sent an email to SPT asking if their exhaust would fit the new 07' 2.5i. he told me that they didn't make an exhaust for the 2.5i becuase they found that there were no significant increases in power or performance. if this is true, why do so many people buy aftermarket exhausts for their non-turbos... the sound?

the only exhaust part SPT makes i thought was an axleback which doesn't give you anything...just make it sound different...you need to replace header back or cat-back to see any kind of gains

Your power gains with the NA engine, 'specially with the 2.5i are going to be very small untill you can get an ECU reflash.
But I picked up an SPT and love the way it looks and the fact that its nice and quite.
