Ever use one of these?
Just curious if anyone has used either of these with any success on a rotary?

Yep but what kind of results Ted? I mean how much hp do you think was lost? Was the 20b NA or turbo? Did it quiet the exhaust? There may be a use for this depending on the application.
Edit: Oh yea, which one did you use? The cone one or the black one?

We used a 3" cone right after an inline muffler used as a pre-silencer.
The 20B was NA - no turbos - exhaust was 3" straight through all the way back.
There was a *slight* drop in noise - maybe 3dB.
The Haltech E6K needed to be adjusted to get the car to run good afterward - approximately 10% of fuel needed to be pulled out, as the car ran richer afterward, which implies that engine VE decreased.

I ordered the 3" cone from Summit. It should be here today. I plan on using it in the muffler exit seeing my exhaust doesn't collect until just before the muffler anyway. The engine is stock (6 port FI 13B). The exhaust is; RB Race header & Street port center section capped off with a Dynomax Ultra Flow 6" round 3" IN/OUT. I'll try to get a DB reading before and after, but HP results will be strictly butt dyno. :-)
