2019 BMW M5 Competition sounds ridiculous with a full Akrapovic Exhaust

This one was sent to me by the guy who had the exhaust installed. This thing sounds insane!

I've never had the previlege to properly experience this one but I've heard the Fi Exhaust for the car. It's also incredibly good.



This car also has a tune and intakes so maybe it's one reason why it sounds so good.

I prefer to be more stealth in my M5, just saying.

I personally don't understand the fascination with the machine gun sounds. What happen to just a good sounding growling exhaust?

Kind of embarrassing really. Make people think your car is broken lol.

Don't get me wrong. I bought an M and don't want a sleeper. That's what a m550i is for. But cmon. My 2014 X5 50i has an equal if not better growl than my M5.

Also noticed the M850i has a more bassy V8 growl as compared to both the M5 and M8. Weird.

I do like the pops and bangs when I'm in the mood though.

Sounds just beefy and aggressive enough in s/s+ on the outside and inside.
Yet nice and refined in efficient for long distances, and can open/close the flaps at the press of a button.

I personally bought an F90C for the stealthyness, else I would have looked at an E63s

But each to their own!

I have an E63s and to be honest, I just wish it had more sound on the highway. Personally, I don't want exhausts to be louder when parked. All I want from them is more sound at highway speeds. That's basically it. The gunshot sounds are nice but not as important for me. I see them as more of a perk. With my LCI M5, I got the M performance exhaust, so I'm hoping it gives me what I want. I don't plan on doing any other modifications to the exhaust. On the E63s I want to find an exhaust that just does what I mentioned, but I guess there's something out there for everyone

That's because M V8 uses cross bank manifolds. Changes the typical V8 sound.

I can’t imagine anyone actually thinking that sounds good. It’s just loud pops and bangs. A Ferrari V12, Lamborghini V10 (and V12), Porsche GT3 flat 6, RB26 and 2JZ in-line 6 engines, etc all have great sounding exhausts. Pops and bangs do not sound good.

I have the Remus cat back installed on my M5 (F90) for some time now and I do not like the pop and bangs when in sport+. It was cute at first and now when I am in sport+ I deactivate the exhaust button on the center console to eliminate the pop and bangs / gunshot noise. I concur with others that it is embarrassing when people look at me when the pop and bangs occur when I decelerate. I kept my stock exhaust and I am thinking about going back to the stock setup.

I remember owning a Harley Davidson (HD) motorcycle back in 2003. I installed the HD Screaming Eagle II slip on exhaust and Screaming Eagle high flow air intake and filter. With those two parts combined the bike needed a remap to eliminate the pop and bangs. Once the mapping was complete the pops and bangs were gone.

Having owned numerous Corvettes over the past 25 years, I have installed aftermarket exhaust systems on them. I miss my 2012 Corvette Z06 / Z07 it had the perfect tone without the pop and bangs with the after market exhaust setup.

Is there a flatulence free mode? Why play into the BMW micropenis stereotype?

Valves closed or flash out the overrun to eliminate the bangs and pops. Don't recommend the flash for obvious reasons .. would be nice for BMW to offer a file to remove this under warranty .. not holding my breath.
