Saturn is correct, it will bolt up, but you will lose low end torque, probably not all of it, but I think you will notice.yes, kind of.
keeping in mind you don't have a turbo, so anything midpipe and forward will be different... yes it will fit.
you don't have a turbo!
so you'll need backpressure, so getting some 3" exhaust for a WRX and putting it on your 2.5i will mean you have no backpressure and no low end torque
so ... proceed at your own risk. I would stick to axle-back exhausts.
How did it fit onto the donut gasket? LIke the stock 2.5i exhuast?i got a stock wrx exhaust from a friend, 2000 miles on it for free. bolted right up, runs great. im sure the aftermarket ones will be too big, but the factory wrx exhaust seems pretty good. pipe is slightly bigger, not much, has a nice exhaust tip, and now my car actually makes a tiny lil growl instead of nothing at all. for free, it was a sweet mod
your best bet is to swap out parts w/ a WRX. For FI, it's always best to start w/ a motor meant to take it.alright man thanks for the info, im plannin on force induction it sooner or later either supercharger whenever raptor sc makes one for my car or turbo if a kit is make or swap parts out of a wrx
