rust-proof, no MONZA
quiet, preferably no louder than the stock SVX exhaust, but a low-rumble would be nice
high-flow, want to actually improve performance and reduce backpressure

Best of luck with this Alcyone. I'm with you on the sound, a quiet deep rumble is what I prefer too.

I had a magic JDM aftermarket exhaust on my Legacy Twin Turbo. Deep soft rumble.

One thing to be careful about; you say you want to improve performance and reduce backpressure. If you car is not blown or turbo'd you may make low speed driving erratic if you reduce back-pressure by too much.

Reducing back-pressure will let it breathe better at high revs, important for racing cars. However the pressure and resonance of the outflowing gas is balanced by the exhaust and resonator to maximise gas velocity at low revs. If you free it up too much, your idling will go lumpy like a racer's.

The above only applies to NA cars, like the standard engine. If your engine is pressure fed, then the freer the better.
