Here's my unscientific review:
As far as intake mods go, I already have the AFE intake (which made the largest difference), and the turbo muffler delete (which did absolutely nothing to be honest)
So I bought the CTS TIP. It seemed to me to be such an obvious bottleneck, that I wondered and thought about fluid dynamics, and how air flows from my time in college. I know that the bottleneck will increase the speed of the air going into the turbo. Think bernoulli equation. I think the VW engineers designed the piece in a very intentional and deliberate way.
Anyway, I installed it. There is a definite increase in sound when releasing the throttle after going WOT. But I couldn't say that there's any increase in power.
In fact, on a trip last weekend to up the CA coast on highway 1, I noticed when going WOT at times, I'd hear what can only be described as some kind of 'turbo flutter' or something I've never heard before.. like the turbo couldn't gulp down the air quick enough and was gagging..
I'll keep it on and test it some more.. Putting in some colder ngk plugs this weekend. I'll see if the situation improves.. but if all you want is more sound, yes this will increase sound.
Currently using ED 8.2 tune
I know the ED 8.2 tune produces flutter sub 3k RPM, maybe its just amplified now?
Interested to hear more after you do the plugs etc.

......I'm almost 40, and have learned to be skeptical with mods and the placebo affect.
Its possible this mod adds 5-10 hp.. hell it could take away 5 hp and I don't think I'd know.....
I can see where it would make more of a difference with a larger turbo (R vs GTI) especially if you were pushing more boost. But that being said, I'm sure if you did all the upgrades you might get another 10-15, so you figure the inlet is probably good for some more sound (awesome) and a few ponies here or there.
It's funny when you think about a tiny piece of pipe possibly producing as much power as a horse.
