I have a 2019 Volvo S60 T6 R-Design and was curious if there is any way to program the exhaust valve (passenger side of exhaust) to stay open at all times?
Exhaust Valve Question

second that !!! that's what on my list only if for more sound when wanted
I been looking into this. I was debating taking the wiring to the valve and running it to a switch within the cabin then back to the valve. It would be used to override the position of the valve. I was going to put a Y on the exhaust and integrate an aftermarket muffler on one side. The other would be straight piped to the valve. I leave early for work so I rather not wake everyone up when I start my car, that's where a switch could become beneficial, just leave it closed until I'm out of my neighborhood then rely on the drive mode control it. Mines a 19 t6 w/ P*, I'll have to double check but I thought when in Polestar mode the flap stays open even when parked, at least it sounds like it does.
I'll have to do more research on this idea. But I forsee it happening in the next 2 months as warmer weather comes to NE.
Edit:
Thinking back to this, I will need a 3 position toggle switch. One position being open circuit = valve open, another feeding the existing wiring to the valve, third would be simulating what comfort mode (whichever is the standard) is. I will probably have to take a voltage reading and see what voltage is coming across the original connector in each drive mode to figure this out. But the goal will be to use it as a cut out.

I believe that the flap control servo is CAN-BUS controlled, so while you can open it up permanently (the default engine cold start flap position), you may not be able to reconnect it and have it change state without restarting the car. My P3 V60 Polestar had a similar setup albeit with a flap on each side and I’d played around with it quite a bit. I found that you could also freeze the closed position of the flap by disconnecting the flap connector while the engine was running and it was in a closed position, but it would open again after a few days as exhaust pressure pushed against the flap and the servo motor position slipped.
Hi everyone - in case you are curious. On my XC60 B5 Petrol - the exhaust flap works like this:
- engine off: flap open
- engine on: flap closed (even during fast idle / warmup)
- any mode selected, incl. manual: flap closed
- flap OPENs when Revs hit exactly 4000 RPM and above
- flap closes when RPM goes below 4000

Polestar mode definitely pipes in sound, which is probably why it sounds louder in cabin.
Really?

Hey everyone I know this is an old thread but I’m new here. What does the louder sound sound like? Deeper, or higher pitched? Thanks!

I find the S60 was the most throaty SPA car for whatever reason. Volvo never advertised it or explained why anywhere I could find. Not sure why if it was due the cars smaller size and pipping being shorter or if it was intended by the engineers. For reference in the USA I only saw one T6 V60 SPA so can not compare and Polestars were hard to compare as they always started in hybrid and had electric assist. Not sure if anyone knows why the S60T6 seemed or was louder than the other SPA cars.

Excellent. That’s what I’m hoping for. Thank you!
