I think that they were referring to the difference with the cutout closed and open. Not the difference of a downpipe

Correct.
I'm making about 400whp, nothing weak about the setup, but I feel there is room for improvement in the exhaust. Tired of the catless smell, and stock exhaust is really heavy.
I'm not in the market for another DP, while I'd give serious consideration to Jake's if I were in the market now, I'm not going to see a gain going from one 3" mandrel bent 304 DP to another. I have a TIG and a very well equipped garage. I'll just chop the reducer off my DP, weld a cat into the 3" section, and go from there.

My friend has the Rev9 catless DP. It's a decent pipe for the money and he's running it with stock catback for now.
The Vibrant Ultr Quiet seems to be well liked and I personally was going to do that after DP and CBE.

Just ordered a CSS muffler the other day to go with my Eurocode catted downpipe and Vibrant 17930, don't know if this is uncharted territory but I'm willing to roll the dice. Been looking for a review of someone with a DP/Vibrant/CSS but haven't seen anyone with that setup. So we'll see how it goes once I get it in. 
I have a bit of a Frankenstein exhaust with a VWR catless downpipe, AWE track cat back and a 17950 Vibrant resonator. I hated the catless fumes and it was still a touch too loud for DD as far as I do everyday. Solution was to put a cheapo magnaflow cat way back just in front of my Vibrant res. I was worried that would be too far back and there wouldn't be enough heat for the cat to work but it seems to be working fine based on the total lack of smell. Volume is just right for my tastes now.

Ok guys here i am ; i have a 2015 GTi with a borla cat back. The sound was perfect till the day i install a CTS 3.5inch catless downpipe with the ecu/tcu stage 2. The drone is VERY annoying. I cant even go over 2000rpm cause its too loud and it dont sound good
Do you guys think the vibrant 17930 will help ? Should i install a highflow catback on my downpipe too ? Thanksss

I will look at that this weekend, maybe i have a leak. But it will probably still sound like a garbage can ?

Vibrant resonator should help.
I'd be interested to hear how that turns out... I currently have the catless CTS DP paired up with stock exhaust (which sounds great to me)... I'd like to eventually swap out the stock exhaust for a full 3" option, but I'm confident that regardless of the exhaust chosen, the sound/drone will be unbearable w/o adding an additional resonator or cat.

You need the 17950 - I'm sure it will help

For those thinking of doing this ideally the 17950 would be mounted a few feet further back. The same heat making that cat work is gonna burn the packing out of the resonator

It’s only 8-10 inches from the first big bend to the rear, almost exactly where AWE puts their touring res. But fair enough thought about the heat. I'll post here if I ever have any problems or it starts sounding like it's getting burned out.

The close proximity of the cat made it deceiving.
Here’s two more Vibrant 17950 installs I did recently and a video https://youtu.be/mWRnjL8wZWE
