S4 N/A exhaust?
any suggestions on what to use for mufflers? My car has dual exhaust and the pipes do no intersect, it has magnaflow oval mufflers but it sounds silly.
any suggestions on something to quiet it down and get rid of the weed whacker sound?

Weed whacker?
If your talking about the sound of a rotary, then no you cannot get rid of that. You can deepen the sound if you want and run a single apexi N1' or a corksport fart can, which also sounds good. But if you want quiet, than you should look into a racing beat true duals, they are quiet, but sound great at higher revs.

Racing Beat is the best suggestion. But if you don't want to pay for RB, then check out the Vibrant Ultra-Quiet resonators available from almost any shop (Jim's, Performance Unlimited, etc.). They're about $80 and work very well with the rotary. All the chainsawness will be gone and they are stainless packed.

My car has 2 1/2 inch stainless exhaust from the manifold back. I put a magnaflow universal catalytic converter and magnaflow mufflers on it. It has a really nice deep gargle to it at idle and sounds awesome through the rpm band. It has a very deep tone to it. It isn't overly loud either. I wonder why your exhaust sounds the way it does.

The AeroChamber seems to work well on Chris' car. But his is turbo so the turbo already cuts down most of the chainsaw sound from the engine. He is also running a Vibrant resonator, but not the ultra-quiet model.
Another issue with this muffler is that it is huge. It's about 24" long and weighs 20 LBs at least. I don't think you could ever fit two under an RX-7. His basically starts at the rear axel (1st gen) and ends at the rear bumper.

I've had 4 different downpipe/resonator combinations and 3 different cat-back designs since I had my car (but with the same mufflers), to perfect my exhaust sound. So I don't doubt that the resonators will work for you. They need a bit of pipe on each side so mount them in the middle. What mufflers are you going to run? Also, thick walled stainless tubing makes a HUGE difference as compared to the typical thin wall stuff people use.
