Currently exploring this option on an M8, but having a hard time finding information on its upside other than the sound itself. Anyone familiar with this option? Does it enhance performance in any way?

Thanks in advance.

What car? 850? Must be standard on an M8

The M8. There is an add on option (ZA4) that costs $8,120. It's not on visible on the BMWUSA builder tool site, but it is an option that dealers can add.

I don't think m competition exhaust is the same as m performance🙂

You’re correct. The M Sport Exhaust is what comes standard with the car. The M Performance Titanium is an 8k option

Not worth the price tag. Just get an akrapovic, that way you can at least resell and get some money back down the road.

Here is the Part number, Current price US is 6400.

F91/92 M8 M Performance Exhaust System - BMW (18-30-2-463-405)

I get a 15% military discount from the dealership by my house.
I called them today to get a price but he said he can’t quote me without a VIN number (she’s currently awaiting production on May 9th)

Do you think buying it from the dealership will be cheaper?

Based on the little I've been able to find online, it appears the $8k package gets you a louder, more aggressive exhaust sound with no performance benefit whatsoever. Doesn't seem worth it.

That’s what you get with most exhaust systems.
Some people get more joy from the sound than they do from the speed.
All subjective, but for me I’d rather have the louder car than the carbon fiber appearance package

I guess with it being titanium you get a small weight saving as well.
But I agree...waste of money imo.
$7k for some sound improvement is way over priced to me anyway.

I believe the upgraded exhaust is actually an Akrapovic system that has been rebranded

My car lists an M sports exhaust as a competition feature
So M performance exhaust is additional and adds a little sound?
Then what does the regular m8 come with?

Btw I’m happy with the m sports exhaust. It has a great start up sound, good depth and a roar/burble in high M modes with aggressive driving. Overall it does sound a bit subdued at times and it would be nice to have it sound like a v8 performance car a bit more during regular driving. But I wouldn’t pay much extra to have that

To answer original question, performance gain is likely irrelevant

[MacLean_007]

As people have mentioned you do get some sort of gain, now how much of a gain is anybodies guess. Only way one would know is to dyno the car before and after. You will get a louder and more aggressive sounding car. If you go through the dealership, you can get the exhaust added and will be a line item on the build, so the value of your car will increase.

Here are my thoughts on M Performance Exhaust.

It has a different tone than the M Sport exhaust in my X5M Comp. Tone is noticeably deeper and aggressive. It's slightly louder as BMW still needs to conform to noise standards.

My first mod was to get rid of the secondary cats. It sounds more aggressive but not annoying nor any drone.

The problem with M8 is that it is very well insulated (I actually like that). So to really enjoy the exhaust, you need to open your windows. Next step would be to remove the resonators. I am probably going to purchase the Meistershaft mid resonator delete pipes which will make this a true cat back system.

I totally agree with you, one reason I went vert route was drop top listen to the glories of that engine. It does need some help though, if you end up getting that Meistershaft please share!!!

Ditto. It's why I went convertible as well. I will say the exhaust was louder before the "nurturing" - ask bloozemanAZ if you're not sure about the software issue.

I will say that with a Racechip and Pedal Commander; the exhaust sound is back in full sport mode; but it's not as loud as some exhausts for sure.

I'd definitely go Apkra for exhaust. You might need a new diffuser for the exhaust too.

Good luck.

Pedal commander for M8....interesting.
Link? Info?

Yep, https://pedalcommander.com/products/bmw-8-series

Racechip also sells an XLR pedal box. But it wasn't available when I got my pedal commander unit.

Pedal commander is the original and makes them for every car almost every model.
Racechip XLR might be more tuned for bmw since it's made by them in Germany and specifically for bmw.
But XLR only has like 8 settings, where pedal commander has 36 different settings.

I have a pedal commander in my m850i usually set to City mode and I alternate between -2 for a cruise to +2 for more active driving. Occasionally I will use SportRace +4 ; but normally around City -2.

In my x5 vermilion; I typically run Sport +1 but I'll do City +4 or Sport+ at -4 sometimes.

Doesn't the car really already have this with M settings or sport mode? I know it effects the throttle curve response of the pedal press similar to pressing sport mode.

Yep and No. bmw comes with sport mode etc; but it's not the same. They build in lag and delays. I can't speak to the XLR; but the Commander definitely opens the throttle body spacer faster and more than any bmw sport settings.

It's hard to explain without driving; but I assure you, tapping the gas on a pedal commander isn't the same as flooring the gas without. It's so violent that a small tap in full PC Sport+ Max on BMW sport+ it will crash the computers and force a full power loss stall out.

Pedal Commander has been proven to reduce 0-60 times by a full 1.1 seconds in the m850i cv. And it doesn't add any horsepower or "alter" anything.

I can't speak for the m8; but I'd wager it will save at least 0.5-1.0 second.

The bmw locks controls too. For example, without PC, in park I can't rev above 3500 rpm. With PC in any settings (city, sport) I can full rev to redline in park. With pedal commander in Race sport+ mode; I can also rev above redline in full park or any gear.

Can't do that without it. I describe it to my friends as unlocking full control of your throttle.
