Been working on various ideas on this for some time... I'd love to get the exhaust out of those fake vents and have the diffuser contain no exhaust cutouts (though there's issues of heat on the plastic, what's behind the vents I think is a metal bumper so that will need to be cut into, ect)...

I may experiment with a more aggressive diffuser but so far, I'm liking this.
This looks awesome! Want!

That looks awesome Vincent! And functional, too. Most cars won't see much benefit from a true diffuser in the back since the rest of the under body is a mess but in our case Honda put a lot of effort into making a flat, low drag under body perfectly suited to it. Will that unit cover the subframe, as well?

Also, I'm assuming this will fit your upcoming exhaust for the Si sedan and coupe?

It is, though it looks like the only change needed on that kit to fit a coupe is a shorter diffuser and maybe slightly different mounts for the wing. And since 27Won's Si exhaust concept is a different shape on the bottom than stock the diffuser would need to be a different shape to fit that anyhow.

How do we feel about this diffuser + quad tip setup? A friend has this on her sedan, the exhaust tips are functional as in connected to pipes, and I personally think it looks great!

There are diffusers available for the regular sedan only. Found it online: http://racingbees.com/index.php?route=product/product&product_id=2329

I am in contact with a friend who makes Carbon Fiber parts, hoping that we can get something in the works for the Si!

So I have seen some of these diffusers on ebay for the past couple years that is similar to the one in the OP, but they aren't made for the Si bumper. Does anyone know where I can get something like this made for my Si? I would personally like a diffuser that is aesthetically clean with exhaust cut outs

No, you won't. The easiest way is appreciate your Si bumper, and the hardest way is to fork out cash to get the regular bumper, buy the ebay diffusers, then have someone to chop and reroute your mufflers.

Maybe you should try something else that works on your Si bumper like the Thai's did.
