Interested in a3" Corsa system?
Got this email from Corsa after my inquiry.
Send a email to jbrowning@corsaperf.com and ask about one.
At this time, we have so many new projects that we are working on that
a
3" ZR-1 system is going to be impossible to build anytime soon.
You are also the only person that has asked for this type of system in
a
long long time...
We would need at least 100 orders before we could build this kit.
Thanks,
Jim Browning Jr.

I just don't see where anyone would get a performance benefit from a 3" system.
I think it's all hype... 3" is what is needed once you exceed 500hp or are running a hot big block, but the small block depends on the velocity of the air to help scavange the exhaust gases...

It's not hype, I hate losing 15-20 hp just for having a 2.5 exhaust. I spent major money on my motor just to have a bottle neck in just about the cheapest part of my mods.
It's going to be even worse when I get the 4" crank in this winter.
At that point I'll probably abandon Corsa and go with the Bassani or B&B

OK Jim 
who never responded to my inquiry about measurements for the Viper mufflers so I could see if they would fit. I ended the email by pleaing again for a 3" system for C4's. It was two weeks ago, so maybe that is a long time.
As far as performance, I thought that scavenging was the job of the headers and collector, beyond that it's all about free flow. While 3"may not be necessary, I don't see how it would hurt. Going too large on the header primaries would hurt. I believe anyone with NO2, forced induction or 400+ cubes would benefit from running a 3" exhaust. Open headers w/out the headache.
