Cool, thanks, looks like that is for the Cayenne S only, not turbo.

I see cargraphic has an aftermarket, which seems to be the same price, but uses a remote control for the switch.

Still big bucks. $2500 USD plus shipping is a lot to pay for a bit of noise. Their HP claims are meaningless. With the Cayenne weight any HP increase would have to be significant to notice.

Has anyone figured out how to use the sport valve to bypass the muffler completely?

Since the valves (flappers) are on the outlet side of the muffler, bypassing it with the sport exhaust valves (flappers) is not possible.

If the muffler is removed or bypassed the flappers would serve no purpose.
