This thread is not about how much performance the Corsa adds.

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)

However, I had PE on my Callaway TT and even with the turbos, it was still LOUD w/ resonance.
I have Corsa on my LT4 and I couldn't be happier with them.

So do both of the outlets flow?? It looks to me that nothing is flowing out the one side, otherwise there would be dirt around it too. There's not even a little dirt compared to the functional outlet. I don't care either way, I like my exhaust. But then I saw this thread and wanted to add my experience. Let me know what and why and the benefit. Thanks

Looks like the outer tip flows because of poor craftsmanship rather than design. This "crack" is further exploited when, the as the OP called it, the primary is plugged.
It could never be described as "flowing", trickling, leaking maybe but not flowing.
Maybe this design is to eliminate the drone...if so good job Corsa.
I doubt you'd ever want to drive your car around with the inner plug, while plugging the outer wouldn't make much difference.

I have noticed on my car and on several other cars that out of four outlets, many only flow thru two.
However, I don't know if there is really any difference in having the four outlet flowing exhaust or the two.
I wonder since this is a cat back system if it would make a difference anyway if it were open.
Somone help me!!!

From the picture it appears that any flow would be minimal.
The size of the "path" is exaggerated since the outer skin is peeled back.
And what does Corsa have to say on this subject? Has anyone asked them????

Poor craftsmanship is probably the last thing anyone who has installed or owned the Corsa would say. I'm not saying it is better or value than Borla, PE, BB, Magnaflow, etc... But I have never heard anyone complain about poor fit or craftsmanship.
I have had my Corsa's for almost a decade and they still look great and sound even better than when new. The stainless steal will probably last another 20 or 30 years.
I have never had any problem with resonance at any rpm; even after the hotcam mod. They are pretty tame when puttering out of your local neighborhood but will scare the crap out of the ricer kid making his little lawnmower noises next to you at the stop light. It is a very well balanced system and is of TOP quality.
There are a lot of choices out there. Each individual has different preferences. For me, I think there are some things other systems do better than Corsa, but it's at a cost of something else, usually resonance. Each needs to choose what is best for them.
However, if Corsa is still making the same quality product I bought 9 years ago, I can say this is a case where you truly get what you pay for.

Man, thats lame for me. Ive got magnaflows with dual tips and if you look in them the main pipe splits right down the center into both exits. Cheap and great looking and of course, bit of resonance even with an x pipe put in. Always tried to figure out how corsa did it to try and replicate it, thanks for explaining it. Guess It cant be done... or can it... me's has an idea.

I would like to know what Corsa has to say on the subject.
Does someone on the forum have a connect at Corsa that we can call and pick his brain? I guess we can just call them and ask a tech the question on the functionality of the quad exit exhaust.....

The resonance cancellation happens in the larger channels surrounding the main pipe. It appears, in the design of the C4 muffler, some of the exhaust pressure can be released into the overall body of the muffler. The second tip seems to function primarily as a pressure release. They are both functional, with different functional requirements.

I don't think any Thread with Corsa in it will end well.
If you do a search for Corsa, almost every post will have someone saying, only one tip works or, my friend says one tip works or I talked to the Corsa Rep and he said only one tip works or my friends friend had one and only one tip works or....
That's why I made the videos years ago and I repost them every couple of years, for new members.
There are so, many Corsa haters for whatever reason that the first thing people think when they see a Corsa thread is, "I'm not going to spend $1k+ on a system with one functioning tip."
They don't even read the entire thread. They think Corsa owners are bragging or something. Besides the stock C4 exhaust system and a few stock replacement mufflers, Corsa is the only quality aftermarket exhaust system with no Resonance.

99% of Corsa owners could give a crap if both tips flow.
To the OP, all you're really bickering about is people's definition of "functional". I think its pretty clear that most understand that virtually all flow goes to one set of tips and a very small amount goes to the other. Some will call that "functional" and some will not call that "functional".....................so what exactly are you trying to prove?
Your making an issue out of nothing.
