CORSA's Patented RSC™ Technology allows us to acoustically style the sound of your Corvette to give you the true voice of performance without the annoying drone while cruising.
No Drone - This is what sets us apart from other exhaust manufacturers: RSC™ technology eliminates "problem" frequencies that cause interior drone/resonance at cruising speeds. You can add CORSA and enjoy your car at idle, on acceleration and while cruising down the road.

What are you basing that on? From past conversations with Corsa, my impression was this:
Like most Corsa's, there is only one pipe and one resonance chamber in a muffler. On systems with dual tips, they generally "Y" out to two tips. On the C4, there is no room to do that because the tips have to be so short. So one tip flows and one does not.
Apparently to address the appearance concerns, they added that little stub of pipe to get some flow into the case (the second tip and the case itself is mainly for appearance and so the muffler hangs properly). I suspect they blocked the tip off mostly so that only a little exhaust flow went in there (as it is bypassing the resonance chamber). This has not addressed the appearance concern, though, as the outer tip still stays much cleaner than the inner.
If you plug the outside tip, do you get a lot of resonance? Why do you say it's for resonance control?

I should've wrote, "Outer tip" = Auxillary Exhaust Flow.
I'll edit the post.
The Primary exhaust pipe in the muffler case with the multiple cylindrical tubes around it, is how the sound is cancelled out and Resonance eliminated.
I'm just guessing that the smaller exhaust pipe inside the case has something to do with controlling the sound also, as part of the complete package.

I dont mean to sound like a smartass, but why are we talking about this?
Every Corsa system on a C4 I see looks very similar to this
It doesnt take rocket science to figure out what is working, and what isnt. The tips lool like crap imo.

It doesn't flow enough for any performance gain but, that's not what this thread is about. I'm just showing that it's not a dummy tip.

That's the whole point of this thread. Even though the Outer tip doesn't get as black as the Inner tip, it still does have exhaust coming out of it.

Ok gotcha.

I have these mufflers and I really like the sound they give while cruising and on hard acceleration. They are still considered dual exhaust because they extract exhaust from each side. The outer pipe only lets out very little about of exhaust, I can feel it when i put my hand there. When on highway there is no resonance/drone. I recommend them.

I don't know why this thread makes any difference to anyone except the thread originator who is trying to prove that the outside tips also flow exhaust. I don't think they do.

Yeah, yeah I get that part. But I want a test that proves to me that its the outer tip flowing a small amount of exhaust that created this effect. I doubt it has anything to do with it.

In Corsa's words, this doesn' t say anything about the outer tips flowing anything. Also, there is NO residu from exhaust in the outer outlet. Let's get Corsa to say either there is flow thru both out lets or there is flow thru only one outlet.

Any information needed more than this will be like beating a dead horse.

Watch it again. If there was no exhaust flow from the outer tips, the engine would not run. The tips don't get dirty because the flow is Very Minimal.
