Ol' Dirty Noodle Posted May 7, 2016 Report Share Posted May 7, 2016 I bet it's all code for electronically enhanced to sound better/different, jag does it, even has speakers in the car dedicated to altering in cabin exhaust noise. Maybe Steve Ghostshadow can chime in, he's had just about everything come through his shops Quote Link to comment Share on other sites More sharing options...

But they're also using butterfly valves to alter the sound on demand. See below how two of the tips have vacuum controlled valves. It'd be real easy to operated it with an electronic solenoid. And in BMW's case, apparently controlling that solenoid with Bluetooth instead of running a wire to the back of the car. I think Corvette and Ferrari have been doing it for a while. Porsche does it too. Is there an industry name for this type of feature? I want to call it a variable exhaust valve, but that has too much overlap with cylinder exhaust valves.

Not the best sounding thing BMW has ever made. Wait, maybe you can eq the sound of the exhaust on your stereo... BMW active sound uses microphones in the engine bay to pipe sound into the speakers, usually 3-4% of the noise you're hearing is from this system. It cannot be EQ'ed or altered, it's true engine noise and not synthesized (looking at you, Audi) Quote Link to comment Share on other sites More sharing options...

And, like I and Gabe have stated.. Its fucking stupid. Who the fuck wants engine noise from the engine bay? Most people want to hear the exhaust note..Not the engine bay noise.

BMW has used an "active" exhaust as far back (maybe further back..?) as the E46. I was helping with a manual swap on a 325i and it had a vacuum-actuated solenoid in the muffler. Electronic eliminates the need for a long vacuum line, that's a definite positive. Quote Link to comment Share on other sites More sharing options...

This is nothing new. You could buy electric and vac. Controlled setups from Summit etc for years. I remember a kid in my highschool auto shop in the 80s fucking around with solenoid flappers. I want a car that sounds good all the time. Not quiet and loud.. Or ok and then "racecar". But, hey, whatever blows your hair back. Quote Link to comment Share on other sites More sharing options...
Timbo Slice Posted May 9, 2016 Report Share Posted May 9, 2016 I mean..I kind of want to put an electronic cutout on my XC90. That would be sweet. As far as the BMW's go, I'm going to side with "Fucking Stupid" as well. Quote Link to comment Share on other sites More sharing options...

That's the main reason we shouldn't listen. and again, you can't stop the propaganda.. yet you don't even own or drive one. Just like a politician.
