There have been several posts about the sound of the Macan at startup, or when sport mode, or when accelerating hard. I searched the web and came up with a few quotes folks might like to see. These are from the original press release (1st quote) and a couple of early reviews.
Some Porsche models apparently use a pneumatically operated flap/exhaust damper that is normally open but closes based on an engine/chassis controller signal. Apparently some people have pinched off the vacuum line so that the valve stays open or they remove the vacuum line and plug the line and cap off the actuator port so as to keep out debris. My vehicle is still a month or so from delivery but I was wondering whether anyone has looked under their vehicle, found the valve/operator, and defeated its operation so as to get the sportier sound at all engine speeds? How does it sound? I believe the valve may be on the right/passenger side exhaust? If it works it may be a reasonable option to avoid considering an expensive aftermarket sports exhaust system.
Here's the quotes: “All Macan models feature an engine with sports car characteristics and they sound like a sports car too: The sound of the Macan is robust and emotive, indicating that the vehicle is always ready to demonstrate its capabilities on any terrain. As part of the sound design, the exhaust features an internal flap that is map-controlled and load-dependent, which dictates when it opens and shuts.”
“All Macan models feature an engine with sports car characteristics and they sound like a sports car too: The sound of the Macan engines is robust and emotive, indicating that the vehicle is always ready to demonstrate its capabilities on any terrain. As part of the sound design, the petrol models include an exhaust flap, in addition to various other components. The flap is map-controlled and load-dependent, which dictates when it opens and shuts.”
“Plus, the Macan sounds like a Porsche. Engineers have built a flap into the exhaust that muffles the engine note below 2,500rpm, but opens above that to release a thumping Mercedes AMG-like roar. “
