I'm definitely interested in hearing it as well. Looking forward to your video.

Spinny, what's your exhaust setup again?

Noelle high flow catts( no cel) , Eisenmann centerpipes ( res delete ) and comp mufflers w/ exhaust miester.

I have done the resonator delete, not loads of extra volume but sound is sharper and crackles more when revving at idle. NO extra drone at all.

Agreed on the sounds. I think the note is a bit deeper as well.

I take it there are no issues from the engine by removing the resonators?
Are they there to purely change the exhaust note, it wont upset the ECU by removing?

Who removes the resonators?
Lease ok?
State inspection issues ? Or unlike Decatted?

You get more sound- especially on quiet turbo cars like the M5... I did it on all my Turbo Benzes and Audis too. Its undetectable on a lease return but you can always put it back on for about 100 dollars at any decent muffler shop. No CEL as well; the resonators are post cats.

You should do a youtube search for resonator removal on the Benzes- some good sounds.

Thank you Vic
Appreciate your detailed reply
I am considering it seriously...

Also found this CLS63 2012 AMG after resonators delete and WOW!!
So mean!!


Happy Memorial Day sir...

I'm thinking of deleting the resonators, removing the wadding in the mufflers and putting straight 'Y' pipes in replace of the perforated baffles. How do you think this will sound?

Enjoy video of it.

What exhaust is that...doesnt look stock

Its stock actually. I just changed the tips from IND to gloss black with the M logos but I deleted the resonators today that's all I did to change the exhaust.

Very nice sound man!
1.How much total cost?
2.How did you do it?
Details please!

It shouldn't affect warranty or lease? I can't believe that resonators are there only for noise reduction or should I say for fun reduction! ! Any other possible functions! May I ask how it doesn't drone when M5 with resonators and with valves open does have some drone to my ears! BTW I don't mind what I am hearing and if this is drone bring it on baby ... hahahaha .. Joking

Thank you

Awesome, and I cant believe my thread still lives. Whats ironic is I never did this on either of my S63tu cars. Now I know what I will do if I go that way. I have done this on all my AMG TT cars and even did it on my RS7 and the sound gains are strong.

@soooma

Its a rather easy muffler shop job:

rack it
cut the stock resonators out
straight pipe the gaps where the resonators were
done

My muffler shop (well known for welds) charges me 150 dollars each time I do this. I have never had a dealer issue with this regarding a warranty.

1. It cost me only $100 but it depends on the shop.
2. Vic explained it pretty well below but they saw off the two resonators in the center of the exhaust and they replaced it with welding a thiner straight pipe with no exhaust chamber holes to reduce sound and clear sound. Will post pictures of my car on the lift and the resonators inside look so you can see the chamber holes inside. its also some minor weight savings.

haha I do not know why it does not drone. But when at 3000 rpm I flow it and let go you hear from sexy drone. But not just regular driving its like stock

Its a 150 dollar job to remove and another 150 to add back if you are worried about the 3rd party inspector getting under your car at lease term (which they never do).

Hi..contemplating doing the same but slightly confused

Resonators are the centre silencers or the boxes that the tips attach to as colleague had rear boxes ( where exhaust tips are attached) and also the centre resonators (silencers) and car sounds pretty loud but not too deafening.

Has anyone removed all 4 and any issues from removing the centre resonators and replacing with straight pipes.

Also presuming car has 2 cats on each side can one of the cats be removed without any errors being displayed..

Thanks
