CLS550 2014 4matic need advice

Hello everyone.
I hope you are all well.
Been reading a lot of your awesome posts here and today decided to join.
I bought my CLS550 2014 4matic 2 years ago.
And thinking to do something to refresh it. Tried to read and search but didn't find answers.
1- i want it to go sound louder without spending lot of $
2- what do you think of chrome delete?
3- does the breaks normally sound like grinding all the time you press the brakes slightly?
4- is there body upgrade from the backside?
5- i feel bit lower power recently and sometimes the gear shift makes the car jump (jerky) not sure about the word to explain.
6- should I change spark plugs?
7- I got it with the front grill upgraded to 2016-17 but no side lights and it's always on the dashboard to check the lower lights.
8- do you think the ECO mood should be on? I heard it breaks the starter. Tho I'm trying to save on petrol because the price is going up crazily. Should I clean the injectors will that help?
9- last and not least. What do you suggest to change or upgrade? (Not costly)
Thank you a lot fam. You are the best and I'm proud owner of CLS and proud to be your friend here too.

CLS400 4Matic EC Tuned
If you want it to feel like new, then it's an ECU tune. The performance will make your car feel like its a whole new car. A tune on that engine you have is a must.

Is that a dent in the drivers door? (4th pic) If yes, I'd start by getting that fixed.

These are MY personal opinions:

1. - Cheapest: Remove the center resonator and add straight pipes. I did this.

(
)

OR Remove the center resonator and mufflers OR Downpipes and full exhaust. All depending on your budget.
2. - Personal preference. Do what YOU like".
3. - No they don't. Have them checked or replace the rotors and pads.
4. - Lots of aftermarket diffusers and exhaust tips available. Googles search is your friend.
5. - Have the car serviced and scanned for codes. This will tell you a lot about the car.
6. - Have they been changed? Service history? Can you do them yourself? Spark plugs should generally last around 100K kms. (60K miles)
7. - That code can be programmed out using STAR diagnostics
8. - Your choice. Use it or don't.
9. - This will depend on your budget and ability to do any work/mods on the vehicle yourself.

Good luck.

I personally recommend just deleting the mufflers - it creates a muscular but not harsh sound.
I agree with an ECU tune. My CLS550 has the Weistec Engineering 540/715 tune - it's reasonable and transforms the car into a beast with no other modifications.
You need brakes!
Spark plugs are recommended to be changed at 60K miles but realistically last to 100K miles or more.

Deleting just the resonators gives a great sound under load but almost stock sound when taking it easy. Cheap mod and best of both worlds in my opinion.

Agreed with all of the above posts. and I definitely agree with DigitalDisaster, my car is tuned by Weistec as well, and it's a completely different car. I like the chrome delete, especially on black cars. Add a spoiler, not too much else is needed. They're classy cars and look incredible when they're fixed up. Wheels and lowering you can do as well. Lowering is done by a module that you plug into the OBD port, super simple and it looks good too. Good luck and I hope you're enjoying your car.
