The noise is much better, too. It has the same characteristics but deeper, more pronounced, noise has more volume. Also, on downshifts, it is louder.
This should be the best mod for our cars.

Similar experience here - went from PSE and stock headers to soul exhaust and fabspeed headers. Sound multiplied by 2.5, very audible drone, and sound was boomy. (However this may have been the older soul valved exhaust)
kept the fabspeed headers and put PSE back on - that is my perfect sweet spot.

Especially in higher gears (3rd & 4th) car’s pick up from 2000-2200 rpm is faster and throttle response is noticeable better.

I bought them from FVD Brombacher Germany. They sell HJS 200cell cat core.

You can't have your cake and eat it, too. Any removal of existing equipment that isn't being replaced with like equipment will increase drone. Sport cats, cat deletes, headers, muffler bypass, etc. -- all will increase drone and volume to some extent.
You get power by removing restrictions in the exhaust. Without going into some crazy helmholtz setups, you can't remove restrictions without resulting in more volume and drone, among other potentially undesirable effects. It's just the nature of the beast.
Soul has videos of almost every exhaust configuration they offer available on their product pages, those do a pretty good job of letting you know what you're getting into!

I love when people just generalize information without providing facts to back the misinformation they are spewing. I have Soul long tube headers on my 2014 Carrera S, Porsche factory PSE, and a custom tune. I am glad to report accurately that I have made more horsepower (based on manufacturer specs and multiple dyno runs. first run resulted in around 350 HP), have removed restrictions (no cats), increased the volume of air...but have not...HAVE NOT experienced any amount of drone or any other undesirable affects. If memory serves me I put down about a final 367 HP to the wheels...Unfortunately I did not do any runs prior to the mods, but my research showed somewhere in the 10-20 HP is average gain on the N/A motor with these mods...closer to 20.
So, I have my cake and am eating it too...

[QUOTE=AdamSanta85;17241265]Still very happy with them. Don't feel the need to reinstall my X pipe muffler for more sound, though I haven't listed it for sale yet. Happy with the volume from Headers + PSE. Definite seat of pants gain in power, especially down low.
I bought them used from RL marketplace for a hell of a lot less than they sell for at retail, but any quality catted header should perform about the same, so buy whatever you can get the best deal on.
Install was pretty simple, however on of my O2 sensors was seized in the OEM header so I had to replace it which added some extra hassle as the connector is.... no where near the headers and actually behind the tail light...
What I installed

Sounds like you did it it yourself? If so, how long did it take?

The headers, maybe 3 hours themselves. I ran into an issue with one of my O2 sensors being seized in the OEM header, which required me to replace the sensor... the connector is behind the tail light... Also on the Fabspeed headers (not sure about the other brands) a couple of the bolts from header to engine are pretty difficult to reinstall due to the location of the head primaries. I had to use a combination of swivels to get them tight. Overall it really wasn't a bad job, had that one O2 sensor not given me trouble, I would say it was pretty easy.
To get under this car I just jack it up onto some ramps. Gives me plenty of room to get at exhaust, plugs, oil changes etc.
