Loud version will be louder at WOT, should be about the same around town as the factory muffler. Most customers that don't need to pass dB limits at tracks will likely want the "loud" version. I'll get some video of it once back from a business trip... Testing the quiet muffler and our catted headers on the 991 this Friday, should be the quietest setup for those that want more power!
Exactly what I want.

Also our Race Center Muffler (as it's catchier than loud) is on our 991 GT3 with catted long tube headers, and is in the midst of testing. We're really checking for low rpm resonance or other issues. So far so good. This prototype is likely on it's way to PT3 soon!

"Loud" Center muffler finishing up fab work this week, and the 2nd quiet muffler will be heading to BR Racing next week for one of their customers. We'll have two Quiet prototypes being torture tested at Laguna on the 4th of August. One on a 991 GT3 with Side Muffler Deletes, and one on a 997.2 GT3
I love Laguna but hate the 92 db restriction

The intent of these mufflers is that they are a lifetime purchase, no more failed, cracked center mufflers, and with your choice of reducing dB's or singing the song of my people!

Update from Laguna:
991 GT3 with side muffler deletes previously blew 101.9 dB with turnaways. They're testing our Street GT3 Muffler (Quiet) with turnaways on a 92dB day. No flags, and he was 3rd gear and flat to the floor up the hill!
Pleased and a little surprised it passed with side deletes. Means our catted system will also likely pass with the quiet muffler at Laguna and there may even be hope for our Race headers to pass!
Customer is working to get dB readings, videos etc...

So we're running them without any GPS valve control, so if the driver has their foot in it above 3000 or so RPM's and 30-40% load the valves will be open (sport mode).
We're actually looking at 3 versions. Race (a little louder than OEM), Street (current quiet, quieter than OEM) and we can make a quieter version yet that we're going to put together that's we're going to call Laguna. Once Charles is back from vacation we'll put that one together.

I hope race version will produce a great and glorius sound note at wot, not just "a little louder than oem"
Please build a real race version, which deserves its name: people who want quiet options has many options to deal with.
If you do it do it really, don't hesitate and don't be shy.

997.2 GT3 had no issues all day at 92dB day as well!
Both Beta testers gave a big thumbs up!
Looks like we gotta get the preorder list together...

I'll report on the new Race version this coming week as I'm heading back home this weekend!

The current quiet version has no losses and passed for both 991 GT3 with side deletes and a 997.2 GT3 on a 92dB day. We believe the Laguna would also be no loss, and will always test it to be sure!

Two points are importants and is what I'am anxious about: sound level and sound note. I can't wait to heard the balance between both points.

This is Bruce from BRracing...it was our customer testing the new Dundon Motorsport quiet exhaust on his Porsche 991.1 GT3 w side deletes. Great, amazing results.
Fitment is spot on.
Great to work with (Dundon Motorsports).
Have used other products of theirs as well w great success.
This to us is the perfect solution for Porsche GT3 track day customers wanting that combo of street car / track car, power, and ability to make sound at tracks like Laguna Seca.
No more fussing around w other add-ons, or work-arounds, just install the exhaust and go play.
