Thanks for answering many of my questions. It's very interesting to see the stepped Section 1. I would love to go with your Section 1, but my SS V2 Stepped Headers have an outlet pipe diameter of 60mm/2.36". It would have been perfect if your Section 1 diameter matched my headers, hehe.

My understanding with stepped design headers to optimize power throughout the whole powerband. With narrower primaries, you have nice low end torque gains, but with bigger secondaries, you maximize high end power. So does this concept apply to your Section 1?

I would be very interested to hear more about the dimensions and measurements of your headers to see how they compare to the SS V1 and V2 Stepped. If they prove to be superior to the SS headers, I would love to purchase a set from you!

Thanks again for clarifying my questions. Based off the latest photos, it looks like you guys made a very high quality system! With regards to E46 M3 interest, how many people would you need to make this worth your time? I am fairly active on M3Forums so I would gladly spread the word about your products to spice up some interest.
