Standard GLA AMG vs Performance exhaust

What is the actual difference between the standard GLA 45 and the "performance exhaust" anyways?
They obviously sound different but in what else do they differ? Hardware software?
Thanks.

What is the actual difference between the standard GLA 45 and the optional "performance exhaust"?
To Gadget1 If it turns out to be hardware related, do you want to trade?

I already got my 45. As you can read in my post I know the "performance exhaust" is louder - but why?
Anybody with some real technical information would be greatly appreciated. Thanks.

Would you know if it is now just a matter of removing one? Or is the single one different also -as I would suspect? Is there any coding in the software involved that i.e control the flaps differently?
Yes I believe you can remove one. The below threads should be of some help.

Not sure if I need to change anything - local MB dealer says I will screw up the back pressure and the engine won't run right...??
So, if others are removing a mid-reasonator to create a performance exhaust system - can I add a reasonator to take out some of my noise and still keep the performance?
Has anyone done any soundproofing to address that has actually worked? Sounds like some of the "noise" is a reverb that is common in SUV's - I noticed when I opened the sunroof yesterday that it really cut down the drone/buzz.
I have the performance exhaust on my GLA45 AMG and have delighted in what one commentator quipped "startles pedestrians."
I bought my car in Houston in the intense heat of the Southeast Texas Summer. The car was "throaty," but it IS a Mercedes and so I did not think it too excessive.
Well, recently we have started getting our Mediterranean fall temps and the other day I put the windows down, the top back and was astonished at the noise level.
Not a bad level, just, well loud. I love it. I revel in it. I feel like a boy in HS with a new muscle car. Freaky.
'scuse me, got to go "startle some pedestrians."
When I'm cruising around town or down the hwy, I don't want allot of noise. It's unnecessary it doesn't denote performance, just noise! However, I want a choice when and where to utilize it.
