I like it. First Try Y design outside of Hytech..

All others are just tweaked OEM designs..

Looks like they released it...but no dyno yet. Are there any numbers on this header anywhere?

looks like the invidia. But for 750 it should make gains otherwise there are proven alternatives for a few more $$$.

I love how it says it's dyno tested proven gains, but no one ever supplies the dyno lol

The OEM design is a standard Tri-Y with a better configuration. The thing that I believe is bad about designs like this one (and Hytech's) is that they are pairing cylinders 3 and 4 together and 1 and 2 together. By doing this, the pulse from cylinder 3 at the secondary merge collector will cause scavenging on cylinder 3 and 4. However, the pulse from cylinder 4 will only cause scavenging on itself. The same will happen with the pulse from cylinder 2, so cylinder 1 will also get 2 scavenging pulses. So at the engine RPM where scavenging is at its peak, cylinders 1 and 4 are going to run significantly different than 2 and 3. Ignition timing and fuel would really need to be independently tuned for peak performance and reliability, but I don't think any EMS allows separate maps for 2 cylinders. If you just try to use individual cylinder trims to add a few percent more fuel and retard timing a couple degrees on cylinders 1 and 4, that would be safer, but you would be loosing performance at the lower RPMs where 1 and 4 aren't getting double scavenging.
