I just don't think it is feasible. There is a reason the Powerfactor is what $1500+.
Dry pipes are just too complex to build, especially for a company that is wanting to create a "new" pipe.
Assuming they will use a proprietary exhaust manifold, which either requires billet which = expensive for the end user or cast which = major investment up front for the company. Quantities are so limited in this sport they will still have to charge a large margin to ever recoup the initial cost.
Then the chamber itself, you have double the initial tooling cost for an inner and outer chamber, more than double the assembly cost to weld the chambers.
And this all assuming they don't spends thousands in prototype & development work.
