Jeff, I can confirm that the Fabspeed Side Muffler Bypass is a droneless application when installed with the stock GT3 center third muffler. I just had the install this past Tuesday and it offers the sound enhancement that I was looking for and the big plus is you drop 35 lbs from being the rear axle.

Me too. Except from what I've seen video clips don't do the "live" sound justice... Oh well its better than nothing...

But to me, the deeper tone of the GMG bypass detracts from the quiddity of the 991 GT3 engine.
Makes it sound like someone gave the GT3 an enema with a Borla exhaust.

As Euro is quite weak at the moment. I m going to get the FVD header with cat + FVD side muffler bypass. Remove the SW bypass, restore the factory rear box. Hope the setup will turn out good result. lol

Interesting as I think this may be the ticket to proper sound with some added performance.

Race header is the way to go IMO

The video is of my recently sold GT3, which was outfitted with:
Fabspeed race headers (no cats)
Side muffler bypasses with valves
OEM rear center muffler
Video starts with sport exhaust button "off" (valves closed)
Video ends with sport exhaust button "on" (valves open)
It's easily apparent that with the valves open there is a significantly
more aggressive sound. Having the PSE function retained with this
setup is very attractive IMO.
Should you elect to not remove the OEM headers for the race headers without cats, the sound will be slightly subdued but still much more aggressive than the stock exhaust.

Love the sound these make but like some who use the car as a daily drive or on a long commute would the noise be unbearable?
Also with the new headers fitted without cats does this not put the engine check light on?
