stand up exaust sound problem
Hi i Had attached two different videos. one is 2018 GTC convertable another one is 2019 GTC Coupe.
I found out a difference the 2018 gtc convertable wont have the pop sound when it start up. but the 2019 GTC coupe does have a pop sound last for about 2 second when it start. I am curios any one's gtc convertable has the pop sound when start engin. about 2 second the pop sound sound really nice.
I am assuming the 2018 gtc is something wrong. leave comment below please

I have a 2018 GTC roadster and it pops on startup - this tends to happen when [1] the car is in Sport or Sport+ mode with the exhaust button 'on' when you start the car and [2] if you start the car and lightly press the accelerator
Not a great way to make friends with your neighbours on a cold winter morning, i will tell you that.
To start the car in Sport/Sport+ mode, it needs to be in that mode when you stop the car previously.
Restart within 4 hours (as I recall) will start the car in the previous mode.
As a general rule, the pops and crackles are only in Sport+ and Race mode (usually above 2500 rpm)
Some of us have after-market cats, downpipes and exhausts that considerably increase this. Not me - still stock as the AMG sound is still pretty amazing!!!!
I will be very surprised if the dealer is able to 'add pops and crackles' - and it is not likely to be an exhaust fault.
Do let us know!!

I am going to dealer to do a recall : (Retrofit Protective grille for additional cooler) on ocat 5 2020 and I will ask them about this question.
my friend told me to change different gasoline to try. i am current getting 94 from CHevron. he told me 94 from chevron is bad. ask me to go to Shell gas station for their 91 is better to see might have better sound !

I am not sure it is the fuel octane rating that delivers the pop but let's find out when you speak to your dealer!

[QUOTE=Jack Huang;8170253]Mine is 2018 GTC convertible. It is also possible that what I consider a pop is something you would NOT consider a pop. So it could be a perception or definitional thing as well.
