header questions

Does anyone build tri-y headers for the c6? Why or why not? It was my understanding that 4 into 1 headers were for high rpm, and tri-y made better torque. My honda s2000 had a tri-y and had a torque peak at 7500 rpm and a redline of 9000. It seems that would certainly be high enough for the c6. The honda also had a volumetric eficiency of about 110 % at that 7500, so tri-ys would seem to make sense. Any comments?
Thanks,
Roger

It's a little difficult to compare an in line DOHC 4 cylinder to a pushrod V8. Different designs and different goals.

Also contact QTP (www.quicktimeperformance.com), they have Tri Y C5 headers and should be working on them for the C6 as well.

If you look up some of the pre and post header dyno runs, you will see a general increase in the whole power band and not just a bump at the top end.
