The choice of material and service environment will dictate the longevity of the final product. This assumes a skilled craftsman is doing the work.
All of the above may be purchased from a multitude of mills in numerous countries.

You bring up a good point.
You are correct about how the material of the item itself determines very little of the power gains. Looking back now, my previous statement may not have been the best choice of words. The point that I was trying to make was simply this:
These exhausts have shown very nice power gains. What makes them more impressive is the fabrication process that is invested in their quality; from the method of welding, to the thickness of the piping, to the material being used. All of these factor in to the overall design of the exhaust making them lighter and stronger. This results in significant weight savings in order to allow the owners to unleash the power that was previously held back from all of the additional weight.
Also, yes these exhausts may be purchased from different companies. However, only a few are direct, authorized distributors for companies such as Amuse, Zele, and MCR. In order to guarantee more accuracy, and better lead times, it is best to order from a distributor who is direct with these companies.
My apologies for the mixed signals and thank you for your input and knowledge. No doubt that this will now be even more of an educational piece for the members of this community.
