Hmm. Unless they want to use my car for testing and essentially give me the headers, I won't be getting them. However, if they had this larger size before I bought my 1 3/4", I would have bought them.

Ordered the 1 7/8 tri-y's from Pfadt. From what I can see you get more torque in the midrange with them. I called phadt and they were certain that with the new bigger design my 850rwhp would be supported and had some dyno tests to prove it. They said I would pickup more torque with them over using any other header and still have my peak. I'll post up the results when I get them, should be early october

To th OP though, good move going with their 1 7/8s for your setup. Interested to hear about any improvements over your previous setup.
They should be shipping end of this week
