Those without the performance one, how do you feel about the choice?

I found a super well spec car just without the exhaust... even if i spent $3000 on an after-market exhaust it would still be well below another similar spec car with the exhaust option.

I've got the non-performance and I find it too quiet. When the car's moving, it needs a lot of throttle to be heard with the window down, which isn't always appropriate. Through a tunnel at full throttle, I can barely hear it with the window down. I can hear it a little with the window up, but faintly. Because my car was pre-built, I didn't get the choice of exhaust, however my local exhaust guy will be swapping out the rear mufflers for straight pipes (completely non-desctructive as there's a connection at the axle) which will make it permanently like the performance exhaust in loud mode, and that's going to cost £300 ($390).

I have the non-performance exhaust. Like the previous person said, my car was already specced out when I got it (someone else ordered it and couldn't take delivery) so I didn't have a choice. I have no regrets though. I've driven one with the performance exhaust, and even though I initially thought it was something I absolutely had to have, after 2 years with my car I can honestly say that if I had it I would probably put it in one mode and never touch the button again.

That being said, I could see myself maybe wanting it so I could force it to be quiet on cold startups. That's pretty much it.

I think I'd be disappointed without it. I really like the burps and burbles.

The standard exhaust makes the same noises (albeit not quite as loud), it's just that the computer controls when/how instead of you having a button to override if it will/won't make the additional noises at any given time.

For the money I'm getting this car for minus the exhaust... I could use that to purchase something like a Fi exhaust or IPE, etc.

I don't think that is true.

The standard exhaust is not the same noise just quieter, the valves that open by the muffler make a different sound altogether, not just louder. The computer does choose if there are pops / bangs but that is based on driving mode (sport plus and above) not on the exhaust flaps on or off. Volume and tone will be quite different with the amg performance exhaust.

The mufflers between the performance and stock exhaust are completely different, which is easy to tell when you hear them side by side. Not a bad option to get since aftermarket costs twice as much to replace the rear mufflers.

The standard exhaust is also flap controlled. However, it only has one flap in the H-pipe, which is computer controlled depending on RPM and drive mode.

digitalnav

I did not know that. I assume Sport, Sport+ and Race open the flap?

bing1221

No, when you reach 4000RPM it opens.

digitalnav

No way to manually open it besides 4K rpm?

bing1221

Of course, remove the flap...

I think the none-performance exhaust flap opens by air pressure.
My friend has the performance one, when he fire up the car it's much more quieter, since the flap is closed. When he opens it, drive under 2000rpm feels like my 4000rpm sound.

msd3075

It opens based on the engine load, not a predefined RPM.

Floor it at 2500 RPM, and it's louder than if you are going easy at 4500 RPM.

The pops/crackle has next to nothing to do with the plumbing of the exhaust (standard vs performance) and almost entirely with the engine tuning. The "exhaust update" everyone on here keeps talking about is just a programming adjustment to the ECU to how/when/where fuel is added to change the exhaust sound on overrun.

All the flaps on the performance exhaust do is change the volume of the exhaust note, but they have nothing to do with the pops/crackle. It's the engine tuning that does that. Yes, the performance exhaust might have a slightly different tone due to the difference in configuration, but again, this has nothing to do with the pops/crackle sounds.

With the standard (non-performance) exhaust, the volume of the exhaust still can change, but instead of having a button to freely change it whenever you so please, you can instead change it but going to a more aggressive vehicle setting (Sport -> Sport+ -> Race).

Anyone know what that software update number is that updated the exhaust pops?

How do I go in the car settings to see which number update I have?

J.M.G.

Both, the performance and standard exhaust, do have the same flap in the h-pipe, which is computer controlled. The optional performance exhaust button does not have any influence on that flap, as far as I know (EU spec cars). This flap ist dependent on RPM, speed (!), engine load, engine temperature, selected drive mode and so on.

However: The optional performance exhaust has basically two different muffler designs. The driver can choose between both via a push button (or drive mode), which is worth the money, in my opinion!

shoe3k

This is accurate information. Some people think that the only difference between the two is the button activating the volume level. The mufflers in the rear are different between the standard and performance.

just add straight pipes and be done . lol

amanuuh

^or listen to me and get downpipes

digitalnav

^^

Oh you.

I think the better er would be to get the non performance exhaust and then do something the Brabus Valvetronic exhaust or whatever suits your ears.
