The reason for the price is 2 reasons.
1) The GR chassis use a completely different exhaust layout, and if you notice in the images. Its a much more involved manufacturing process compared to the previous GD chassis. More material, and more involved manufacturing results in a higher price.
2) This system is Jasma Legal in Japan (Japanese version of DOT). To have products be legalized by any government or racing group, increases cost. This is similar to SFI or FIA rating on racing seats and other components. For example, this is for example why Sparco and Recaro seats are so expensive. Last I heard about 2 years ago, to get a SFI rating on a seat, cost 25,000 per seat. And DOT/ Jasma ratings can be just as high, if not higher.
