I read that a few guys swear by deleting the Resonator saying its a good first mod but has anyone deleted the muffler? Would the sound be equivalent to running the sport exhaust at ON (valve open) all the time?

AMG 17GT

Yes no and no.

this subject has been beaten to death. Cmon.

M~Factor

is it now? muffler delete in this forum shows 7 results. 1 of the 7 actually mentions a muffler delete not including this one. the reply was about gle63 muffler delete. I'm asking for a GT, if anyone has actually done it.

How about brain dead stupid modifications suck as is "will removing my muffler make me sound like a complete jack off on the street" suck..

If you want it to sound like the valves are open all the time, you could run something like the Renntech EVM, and just leave the valves open all the time!

But don't buy it from Renntech, they are just rebranding someone else's product and charging double.

If you want to go that route, shoot me a pm and I can let you know how to bypass their forced restriction on shipping to the US.

Removing the muffler is a bad idea. It will sound terrible - like a Honda Civic with no muffler. Does your GT not have the exhaust button? Why would you want to replicate the sound running with the exhaust on all the time and not just press the button?!

M~Factor

It does not have a button. Someone has also mentioned that on the GT there might not even be a valve to open so adding a remote won't do anything.
I do see aftermarket exhaust for sale that do not have a muffler in their setup (its way overpriced) that is why I am asking this question here.

AMG 17GT

AMG has several engineers that do nothing but work on exhaust to be able to get the best sounding we ate out there. Mufflers do a lot more than reduce sound.

just remove the secondary cats and see where you’re at.

Orcbolg

In this case, yes, a muffler delete should accomplish the same results as the EVM, and a secondary cat delete would take it up another level.

M~Factor

Agreed. I also have a Cayman GTS with the same sport exhaust button. I wouldn't dare touch the exhaust perfection on it. I didn't think I would miss the sport exhaust on the GT when I bought it because of the loud V8 but now I do. Now I'm trying to fix it. Just trying to get the best option to go about it.

I currently have the 2nd resonator and muffler removed. SOUNDS INSANE. All my buddies love it.

M~Factor

On your S550.

AMG 17GT

I recently purchased a GTC, do you mind sharing with me how to bypass the forced restriction?
And, what would I accomplish by doing so? What is the downfall if any?

RocketFast

same here

Jorge Siverio

Just deleted the secondary cats today
​​​​​ Very nice... albeit I do here somewhat of a rattle in the rear... hmmm

CarbonHan

I don't think the GTS has resonators and what you removed was the secondary cats. I did the same and i hear a rattle with the valves open as well.

Jorge Siverio

Ah yes. You are a good man and correct. I went to dealer and drove with the AMG tech in a brand new GTC and it also has the same rattle. Apparently it's a thing with the valves open.

Surge

It’s certainly not normal. My GTC does not have an exhaust rattle. I think you’ll find it has happened in a small handful of cars.

DriveAMG

And I hear a bit of a metallic rattle sound near idle. Not fussed about it. Will have it looked at the next service.

canucklehead

I think it is more of an issue in the 2020s. Mine is finally fixed after 14 months of MB telling me there was no fix at the time.
Funny enough it took me switching dealerships to finally solve the problem so maybe not so much MB but ****ty service.
