No difference in sound on the intake side. I took short videos of the intake at 3500 RPM, and I can't tell a difference in the sound.
I don't have hard data on the performance improvement. So, I can't really address that. I will run some logs this week and see if there is any differences from prior to install. The car felt like it responded better, but I can't tell if that was psychological or not.

Does this silicone intake tube honestly add anything performance-wise or is it just cosmetic? My understanding is that the reason OEM intake tubes are corrugated is to allow for engine flex. Also, if I used this and an Afe dry filter would there be a difference in throttle response?

The reasoning behind the corrugating is correct. For assembly line production the factory corrugated hose gets the job done, as does the factory air filter. However, that's where aftermarket companies come along trying to milk every last drop of power there is out of what the factory has given us.
Honestly we originally intended the hose to be more of a cosmetic mod that offers a bit smoother and less-restrictive air flow. After seeing the lack of promising results from other intakes on the market at the time, we were shocked to see that such a simple and cheap modification made such a gain. It is nothing new to see a drop-in high-flow air filter pick up notable gains when comparing to stock. With that being said, are the bulk of the gains from the hose? Probably not; we did not test the hose and air filter separately. We wanted to give buyers the option to have performance and/or improve aesthetics at the same time. Both the filter and hose are available individually or packaged together in "Stage 1" form.
We've had quite a few people tell us the same!

I just bought an Afe filter and was going to buy the PRL hose but the nearly $50 (with shipping) price has me hesitating. Do you guys ever offer discounts to CivicX forum members?

I bought mine together, mainly out of convenience. Bought the tube for aesthetics. Was surprised with the outcome. I don't have a logger to quantify the benefits, but it feels peppier and the SI testing that they've done bears that out with a few HP improvement.
