Corsa Outer Tips Functioning Video Proof.
Here Again..., is a Video I made years ago showing proof that Both Corsa exhaust tips do Function. I also, posted this in the C4 Tech/Perf section.
Many members here Insist that the outer tips are dummy's, probably confused by this picture which if you look very closely, you can see a small diameter exhaust tube (circled) that flows exhaust inside and Around the baffle and exits out of the outer tip. This exhaust flow is not for Performance but, is part of the muffler design to eliminate Resonance.
Anyways, This Corsa system is installed on my "91" L98. The tennis ***** are a perfect fit and are pressed in tight.
Here you can see the exhaust flow by watching the attached Ribbons.
Here you can see the Primary tips blocked by the Tennis ***** and the Outer tips still flowing exhaust. This exhaust flow (or leak) is very minimal and is used in part to help eliminate Resonance.

I guess I'm blind- looked like the inner ribbons were going nuts and the outers were gettin a slight breeze. The picture looks like it's plugged to me, a poorly designed plug that allows exhaust to pass.

These videos show that the Outer tips do work and are Not Plugged.
Inner tips = Primary Performance exhaust flow.
Outer tips = Auxillary exhaust flow.
I don't know how much simpler I can make it.

What is the point of this? If the outer tip didn't flow, it wouldn't make any performance difference, since the tip internal diameter is the same as the rest of the system. So there's no restriction from the fact that most of the flow goes through the inner tip.
It does have the ability to flow. But in practical terms, you only get sooty crap on the inner tip. And in the winter you only see vapor out of the inner tip. So in most of the sense that people care, the outer tip is not functional.

Back in 1997, Corvette Fever published an article on all aftermarket exhaust system. Using the same Vette (GS) the dyno few systems.
I dont care if Corsa's system blow out of one or two.
Which exhaust system frees the most horsepower? (I say free because the only way to create HP is by modifying the powerplant)
