All bull**** aside...
The system is probably made by motoria, not xcess power nor ssa.

The systems are ss304. I've had one in my hands, it's not chromed steel, or some crap alloy that ppl seem to come up with.
The muffler and resonator (fc3s) are ss304 wool packed, no fiberglass anywhere.
Robotic tig welding is obvious.
Motoria provides systems for Monkey magic, Uras, and corksport.
Motoria also develops suspension bits, which are undeniably in my opinion (picture evidendce) the same as some JIC, and nams hardware (tie rod ends notwithstanding).
The apexi is painted w/high temp paint. It's true it will rust, i heard accounts of this in freshalloy and zilvia, but not to the extent of falling appart. More in the order of the OEM exhaust rust.
For some reason, I've seen many people be offended by high quality products which are offered at competitive prices. Pseudo elitism to justify an expense that is many times the price of these items is not only childish but rude and arrogant.
