Glad to see you'll pony up if need be. I wonder if the others will.

I don't know how well the test was done. From what I recall, the Kooks 1 3/4 system was used in the test on that 475ish RWHP car.
I believe they countered by pointing out that their 1 3/4 system, which I might add is typically used on those very mildly modified I/E cars you speak of, would never have been recommended for the 475ish RWHP car "chosen" for that test. That their 1 7/8 system would have been recommended on such a car.
When you order Kooks, the vendors will recommend the 1 3/4 system or the 1 7/8 based on your application and mods.
The average guy here is not sporting 475 RWHP so what do the results of a test done on a car with such power mean to a guy with a stock engine?

Without dragging this out, there has NOT been anything that resembles a decent back to back header comparo on a mildly modded car. Obviously no test is perfect (we've discussed this), but this would be far better than what we have to date. Please drop the naysaying, I know you don't care about this since you already own headers...I just wish you would appreciate that those of us in the market may care a lot more than yourself. Error will exist, but it will be less BS than we have been forced to accept in the past.

Hate to say this, but this thread has really wandered from the original posters question. His inquiry was on the Tri-Y design and if it would benefit him. 
Doug Thorley's web site has some pretty good information on the Tri-Y design and how it works. I don't think he makes a header system for the C5, but he does provide some explantory material on his web site.
