Hi guys

Did anyone install this? Thoughts?

Thanks!

AMG.SWE

If it's any help I just installed a ASR module in my -16 Coupé and it made no difference at all to the sound

tobeit

There are many threads about it, Yes, many did. Yes, it changes the sound at low RPM as exhaust valves are 100% open.

PS: lately, with the valves open and in comfort mode at low RPM slowing down I get what I would call mini "pops"..maybe more like burps.

On facelift C63s (stock), I can hear more rumble when car is standstill, but that is about it.
Once car starts moving, difference between running EVM vs. stock car in Sport+ mode not too noticeable.

However, I recently got catted downpipe. This matched with EVM is really good.
Personally, I wouldn’t recommend spending $600 on exhaust valve controller on stock car.
If you plan to get downpipe in the future, then just get it now since Renntech has black friday discount on it.

Didnˋt a good research I guess...

Thanks for the info

Not planning to get downpipe, but thanks for the advice

Honestly if you're pre face lift (not sure if fl one's ever got made) and not going to do downpipes, just do the AWE simulators for 50 bucks. The exhaust will always be 100% open without being able to close it, but on a stock exhaust it won't be too obnoxious.

Finally ordered the renntech module

Let’s see! 😬

Lol same, just ordered today! Looking forward to seeing how it works out!

Catless DP + sport exhaust + renntech VM is the move. 😉

Well If I didn’t just give Mercedes Benz everything but my first born child I’d do all that 🤑
Guess you gotta pay to play though LOL...

I got one maybe 2 months ago and installed it on my 2018 sedan with PE (obviously). I think the sound is great in comfort and at low speed. Makes driving around slowly much more entertaining. Also sound is different tone with 100% open valves, maybe a tiny bit deeper and more raw from outside. When in Sport and Sport + I think it’s louder across the rev band. Maybe it’s just me, but I think it makes a difference in spirited and slow comfort mode driving. The more I use it the more I like it. That being said, I don’t run open most of the time (30/70 closed/open) because it’s my commuter and frankly I don’t need the attention running around town.

pricey but fun, comfort or sport modes. I think you’ll like it unless you’re looking for a ton more volume. As people say, it adds volume at idle and from 0-3000 rpm mostly.

That´s what I am looking for, guess I will like it 😬

I just recently put it on my car. Definitely made a noticeable change at low end. I'm pleased with it. DPs and tune soon.

hi there, I am considering getting the EVM for my glc63. With the valves open via the EVM, does pressing the factory exhaust button on the console further change the sound?

CapoArgentino

At least in my C63 it does:

Does anyone have a facelift C63S with secondary cat delete and the EVM? Curious what this combo sounds like? Really trying to steer myself away from downpipes. lol.

I just installed one on my 20 Coupe with 6300 miles and now the flaps rattle at hard acceleration which makes it sound terrible. Tried the grease fix but it starts to happen when grease dries up. Will try another higher temp grease

GLC63Aus

I suspect I might have this as well, as I hear a bit of a flutter type sound under hard acceleration. Is that the sound you’re hearing? I didn’t come across this being an issue here on the forum, hoping it’s not exactly a common one as I did not think there was an adverse consideration to make before getting this installed!

hotdognobun

Thats the kind of sound i'm hearing. You can mostly hear it in a tunnel. Just ordered copper grease the inject in the flap housing. Should arrive by Saturday so will update you

2020C63s

ya i gog a 2020 c63s coupe and also sounds like a little fluttering when im on fully throttle but only when starting from 3,000rpm usually in 3rd gear i notice it

GLC63Aus

did you manage to fix the fluttering?

I am going to bring the car to the workshop to get it checked out but wanted to check if there was some easy diy fix before bringing it down.

hotdognobun

It drys up after a few months and starts rattling. Gonna try lithium grease next

GLC63Aus

Cools thanks. Keep us posted.
I’ll have to read the forums a bit more to see if there are any other fixes.

funny this is, I never noticed the fluttering before I got the ASR exhaust valve module. Seems like the module has triggered the valve to become loose? Was that the same with yourself?

hotdognobun

I was also thinking of just using exhaust wrap around the valve housing on all three to cover the rattle in the mean time. Hopefully the holes are ok being covered?
