I'm considering a pair for my 14 550. Already did the resonator delete it's just not loud enough and I like the option to stay stock sound when I'm on the phone but loud when it's time to turn heads.
anyone done this with good results? What brand and what's the diameter of the exhaust?

Thanks for starting this thread, I've been thinking about it myself and would love to hear some feedback

Bump for this? I am willing to gunie pig a reputable electric exhaust if you guys can give me some brand names.

I removed the muffler on my c300 and was pretty satisfied but like OP said it would be good to have the option to go stealth especially when you leaving a quite neighborhood at 3am

i would guess the only available thing out right now are the electric cutout exhaust for a cls63.. and you make the modd to a cls550..not much are doing this because the cost of the electric exhaust price.

How much are we talking about here?

here are a couple of brands to get you started.

Ok, did this. I put in the Summit Racing kit because it had the longest warranty of any brand I could find (12 Months). If you want more sound, do this. It is fantastic! I also removed my resonator and put an X pipe in so that should be noted but it just gives the car the sound it deserves. No droning, not too loud to still be on the phone with the windows closed but it's loud enough to make people turn and look.

Next may be a Eurocharged tune. 402 to 530 HP for less than $2k... could that be real does it ever go on sale?

TheChuck

I forgot to attach these.

Nice. Have you had any issues with heat? I want to do this but I'm worried I'll melt the underside of my car!

TheChuck

No issues to date.

That is sick!!!! What was total cost? How much HP gains do you estimate (and how loud???)

TheChuck

The Kit from Summit was like $380 the Exhaust work was $160 and the switch install (hardwired) was a couple hours labor at Eurocharged Orlando.

I think I got 163.4 HP gain from this.
Didn't Dyno it, but I can tell you the Turbos love to breath and it feels faster at higher rpms but I do not have hard data to back that up, it's also colder in FL now than last week and it could just be the cold air. As for the sound it's louder but still a refined rumble.

You know the request is for a sound clip...Get the camera our and let's here it.

BTW thank you posting, it's great to see tuner having fun with the CLS

the video I have is too big to post and I don't have a YouTube channel to post to so no way to get the file posted

Ok so next question is.....would this affect the ECU grades available as I am thinking about doing both. I have done the simple (straight pipe, not the X) resonator delete and love the change. Now I have to bug to keep tuning. I think its the only thing that's going to keep me from buying a newer S550 coupe that I can't afford
