Just tested
-1 oem center and oem side mufflers,
disconnecting the factory valves (weight and heat remain)
: not bad but drone is very audible at 2800rpm
-2 side oem mufflers deleted, a single straight pipe from oem catted headers
to the Oem center muffler
: very aggressive, especially when at idle you will be noticed when parking the car,
the revs quicker, is the cheapest setup ($300) to save side mufflers weight and heat whilst adding character to the car

Patiently waiting on the jcr system similar to the race (side delete+center delete) with a valved silenced option.
Just so my neighbors don’t hate me toooo much.

BMC is already installed by factory
i was considering a more racey version because where i drive there's no dust or sand but had to check the original real size first
that you can see on the picture
yes side pipes are afaik only from fvd,
not bad if you look to enable the 0 to 4k rpm sound
once i get one at reasonable price curious to test the not valved double pipe side delete

in few words works in the 0 till 4k rpm range , not really drones but louder especially at idle (as oem with valve open) and louder at low till 4k rpm and only slightly louder over 4k rpm
very good value for money, too loud for long touring and funny for spirited driving

Considering this for my .2 GT3 with some BCM air filters. I don’t mind a little drone, just not a lot where you can’t hear the stereo and talk on phone or passenger. I’d save $1000 over the valved offerings from other manufacturers. I believe FVD has these $300 single side muffler delete pipes?

I haven t tested the side not valved double pipe yet neither the center delete
but i guess without valves involved any system working under 4k rpm at best can spread levelling the drones whilst others have them in a narrower band, in other words without a center or side silencer exclusively working (through side valves) under 4k rpm on a full silencersless path some of the resonance can t be totally deleted

Thanks. Louder is fine, that's what I want, especially from just over idle to 4k (where the valves are always closed w OEM setup). What I do not want are the drone/booming/resonances at any throttle application between 1500-3500 with forced open valves (plugged vacuum lines). So this seems the way forward for me. Do FVD provide the center muffler "blocking plugs"?

So I just went out and pulled the hose off the valves on the stock exhaust on my .2 GT3. Plugged the hose with a screw and zip tie. Went for a drive. Sounds only slightly better. Not much drone with windows up cruising suburbs at 40-50mph. No drone to me on the highway at 75mph. I’ve had exhaust on other Porsche’s with way more drone. I can handle a little drone (exhaust sound). I want it all to be louder. It does sound better under mild throttle from 2500rpm to a shift at 4500-5000 rpm.
However this isn’t a fix....I’ve got to get this car sounding better...remove those huge heavy side mufflers.
