I'll let you in on a secret. My Greddy cat-back hit the local UPS hub today and should be on my car tomorrow night. It may be Wednesday before I can get audio clips but you should be able to count on having something by then. :drive:
I'm not with PRL but I read your post so I may as well answer it. The Race MAF housing allows more airflow but is not needed unless you plan on upgrading the turbocharger somewhere down the road. As you stated, it will require a tune. PRL can detail the hose sizing, I'm not 100% sure on that.

Allow me to quote @Hondata:
That being said, it probably just depends on how much of a perfectionist you are. Is it safe to drive without a calibration? Considering it utilizes much of the OEM intake system, very likely.
I’m not a member of any of the 10th gen Facebook groups so I can’t say I have seen anything that you are referencing, however unless it’s on an official @KTuner page it’s not anything they have any control over. I am a Ktuner customer and truly believe it is a superior product, but I have no...
Non-Si has 11.1" rotors in the front and what is probably a single piston caliper. i will confirm that after my @Performance Brakes LTD install later this week. The Si has 12.3" front rotors.
While I admit I would not expect any gains from a part like this it should not hurt anything if properly designed and installed. Either way, it may be best to leave it out of your engine bay.
I'm not sure exactly what it takes to install one of these but you need to make sure that everything is sealed up, no leaks on the intake side. Make sure all sensors are securely plugged in and that you did not get anything dirty that you shouldn't have.
From what I've heard from tuners that have really pushed the clutch if it starts to slip you will have an opportunity to make the necessary changes before you eventually find the clutch roasted. If you are not slipping at all now I would not worry about it.
