Besides the $400 carbon fiber hood that does jack.....
Weighs more than half the weigh of a stock hood
The black trim on the sides but none on the bumpers.
Who cares?
The significantly brighter clear corners that don't mtach your cheapo head lights.
You mean the STOCK headlights? 
The air damn lip that doesn't match that amazing can o' spray paint that you probably bought from ace hardware.
You mean the unpainted black plastic lip that is the same color as all the other black plastic on the car
And my favorite..... the holes in the carbon fiber hood where you didn't put the washer nozzels back.
You mean the flush caps that cover up the holes so water doesn't get inside my engine bay
No offense dude..... but your ride sucks.
You sould have gotten an Si..... In the color you wanted.... not a hand me down from your grandma.
My DX is much lighter than an Si with a more stiff chassis, and my engine has 32hp more than your Si and that is stock vs. stock. Who cares about the color, it gets the job done.
And I did install it, and it worked, but I wasn't happy with it. An you wouldn't know this because you have an american Dx.... But stock JDM parts are in most cases better than aftermarket parts.
Of course I wouldn't know anything about JDM parts, its not like my entire engine is JDM
