I also stumbled on a US company selling this;
I contacted them to point out the flaws in the design and to make them aware of us (giving them the benefit of the doubt that they hadn't copied it from us) and got the following response;
We are well aware of the Wizards of NOS but we are not impressed with them.
I was obviously wrong to give them the benefit of they doubt, as they have OBVIOUSLY COPIED my discharge tube concept and they've at least got all the pipes roughly the same length but just as they claim not to appreciate the technology in our products, they also fail to appreciate the flaws in their COPY.
Obviously they're not smart enough to appreciate the detrimental effect of a HUGE lump of ally sat so close to the intake trumpets.
