Quiet Muffler
Hi, I'm going to do a dual muffler setup in my SVX and I need two good mufflers.
My definition of good: low-priced, since i'm buying two, this is a must, sub-$200 per piece 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

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.  Joe

SVXfiles is working on a new setup right now. From talking to him the sound and performance meet your needs. But we didn't talk about price?? You may want to send him a PM.

2.5" single out cat it was quieter than stock!!! AERO AR20, at $82.00 each plus shipping, (VERY FAST SHIPPING) do a great job of quieting down the exhaust. For true duals, don't go ovet 2", and you will prob need 4 resonators total.

Note for folks who don't check Tom's extensive photo archives -- the AERO pieces are used in place of the stock primary cats.  -Bill
