Bugs 77 Posted June 30, 2023 Share Posted June 30, 2023 Has anyone been up close or know anything about the Carbone switchable exhaust? Was wondering what it sounds like in sport mode and how quiet non sport is when cruising, for my wife on long trips Cheers, Phil Link to comment Share on other sites More sharing options...
Ian Comerford Posted June 30, 2023 Share Posted June 30, 2023 I don’t have one but the Carbone seems a lot of money compared to something like the M&K version https://www.carbone.pl/en/products/carbone-active-bypass-muffler-5051 https://mkexhaust.com/active-exhaust-with-pre-muffler/ Link to comment Share on other sites More sharing options...
Chris T Posted June 30, 2023 Share Posted June 30, 2023 But the Carbone is a 2 in whereas the MK replaced the side silencer in a 1 in system. Link to comment Share on other sites More sharing options...
Type911 Posted June 30, 2023 Share Posted June 30, 2023 Pretty sure they dont make it, all the other exhaust stuff is Dansk (and 20% more than most) maybe try and find out who makes it, Over £3K is crazy! Link to comment Share on other sites More sharing options...
Bugs 77 Posted July 2, 2023 Author Share Posted July 2, 2023 Yes agree it is very expensive, particularly went you also convert that to Pacific pesos down here. Might invent something. Link to comment Share on other sites More sharing options...
tea boy Posted July 2, 2023 Share Posted July 2, 2023 I called in at Rennspeed for a cuppa with my mate Ben the other day and he had a car on the lift with one of these exhausts on that he had fitted. It looked to be really well made. It looked like the valves by-pass the silencers all together. I didn’t hear it running. Link to comment Share on other sites More sharing options...
Bugs 77 Posted July 3, 2023 Author Share Posted July 3, 2023 Yes, from what I can see your're looking at pretty much straight pipes when the valves are open, I guess some exhaust pressure would still flow through the mufflers, maybe even 50% but would depend on the exhaust path near the valve intersection.

Jonny Hart Posted July 3, 2023 Share Posted July 3, 2023 Just an observation - a few of the exhausts seem to be using HVAC servos for controlling the 'flaps'. I'm not convinced that these will hold up to the heat of the exhaust. They aren't really designed to live outside in the weather either... Link to comment Share on other sites More sharing options...
Fastcarrera Posted July 6, 2023 Share Posted July 6, 2023 Hello guys, I wanted to respond to all this questions you asked about the CarBone active bypass muffler. First of all, this product was 100% designed and produced by CarBone, it's not just branding. It took a crazy amount of hours and dedication to develop. It was modified countless times to approach perfection. It is durable and weather- resistant, is made of high quality type 304 stainless steel. Below I attach a link to a YT video where it was noise tested by them. https://www.youtube.com/watch?v=MvnbnSoKlMc Link to comment Share on other sites More sharing options...
SurlySurdi Posted July 8, 2023 Share Posted July 8, 2023 Gret bit of kit however looking at those numbers for closed or open how would you expect to pass a noise test on most track days? SS Link to comment Share on other sites More sharing options...
