Quiet down the NA exhaust
I must be getting old because I'm tired of the header + silencer noise level. I'm not willing to give up the power so I'm wondering if anyone has ever tried one of these (or something like it) in the collector:

Rotors still spinning

Those only make a very small difference on piston engine cars so imagine how they'll work on a rotary. The key is to place them in the header collector where energy is the highest. The farther back it is the easier the gasses flow through it and the less it does. Remember heat is energy too and lots of heat is lost by the time the gasses get to the back. I'm not sure that thing would live very long that close to a rotaries exhaust ports.

I'm just wondering if it will a difference in the noise department.
As for the heat? This product is made from 304 stainless. Should be fine. The carbon-steel header would melt first.

Make sure to get the NA versions as they have MORE muffling cabablities. The turbo versons have less (as they need less).
With the exhaust I have the car is only a little louder than stock. I expect with a header it would be louder but liveable.
