This is a very complex design with helmoltz resonator and chamber inside.
This is not just some simply set of straight pipes inside a muffler.
It's not easy to develop an exhaust with almost zero drone on quiet with no loss of power and then on the loud sound the way it does.
Doesn't matter where you take production (assuming same quality), this is not cheap to produce.
Compare it to non valve systems which are similar in price and are basically majority straight pipes inside a heavy big box....
