2X 60mm Wireless Exhaust Controller Vacuum Valve for 930 964 993 996 986 911 | eBay
you can set it up to be manually controlled, or run automatically as per the oem pse. some plumbing still to do - need a 2" cut out on the exhaust to go to the valve (easy enough to cut and insert it at the u-pipe/mid-pipe joiner) and then send the bypassed exhaust somewhere - straight out? into a resonator? back into the muffler so as to bypass the first baffle? there is a guy on this forum selling custom bypass pipes, but are *I think* 1" (2" is a lot of additional piping) so some reducing would be required unless you could find a 1" valve.
