Your link to the dyno plots doesn't work.
Can we get a complete explanation on ALL of the different options for this header.
There's type a and type b, as well as different overpipe designs. If I was going to order one I wouldn't even know where to start at this point. Also, you should include the explanation on your site.
Edit, after reading through some of the posts I'm come to the conclusion that the type A has 15* collectors, while the type B has 20* collectors. The 15* are more expensive because they take longer and require a human to weld, but they make more power. I'd be interested and in knowing how much more, but that has been asked already.
There's also the type C, but that's a temporary measure to get orders filled faster. Nevertheless, I'm curious to know the collector convergence angle on the type C, and if the internal steps help or hurt power.
There are also three options for the 2-1 merge. The 350 (mm?) is left hand drive only and gives the most low end power, but the least high end power gains.
The 150 is the opposite of the 350's gains in that it gives the best high end power and the least low end gains, of the three options.
There is also a 250 that can work with both left and right hand drive and would likely offer the best of both worlds when it comes to gains at both ends.
Is that accurate?
Edit 2, so I just looked at your site, you also offer custom collector convergence angles.
