I made my C43 exhaust sound LOUDER with this simple mod

[@skillzlibat]

I concur. There is very little to no difference on startup revs. All in all, there is such a minor change in exhaust tone. Personally, I would not invest into something like this but it is a good tool to fully control the valves to your liking. Great video and review mate

[@chinweihoe1331]

I am from Malaysia and have been watching your video. To be frank, after watching your videos, I went to buy a 2019 C43 last year. Due to this pandemic, Mercedes Benz Malaysia had few units of 2019 C43 left over as Malaysia was lockdown since march 2020 for about 2 months. As Merc Malaysia threw in some freebies to clear the stocks, I quickly bought one. But I only found out that C43 sold in Malaysia doesn't come with Performance Exhaust but only Sports Exhaust. Been trying to make my C43 exhaust sound better in the aftermarket but couldn't get anyone. This video really helps and will write to them to enquire. Thank you in advance. I also installed a racechip into my car hoping it will make it sound better. It did help but not as good as the Performance Exhaust but the increase in HP and Torque really turn my C43 into a car that I felt more fun to drive.

[@aphexer6]

In case you didn't know, the facelift models (as well as most new AMG's with the performance exhaust option fitted) also include an "emotion start". Hold a shift paddle back while pressing the start button to start the car - it will fire up with the flaps open (likely to the 70% max described) with a slightly higher rev.

[@ABAUTOAMG]

Thanks Aphexer, unfortunately they added this mid 2019 so early 2019 facelift models like mine just missed out! :(

[@realneal000]

I've got one on my Facelift C63S. The main thing about it is that it keeps comfort loud on all the time. Stock, if you go from Sport + to Comfort the sport exhaust goes off leaving you to have to press the button in the cabin to open it up again. With ASR it stays on all the time. it's also good with downpipes to keep the car starting up quieter with valves shut so it's still neighbour friendly.

[@ABAUTOAMG]

Totally agree! It's great that it remembers and keeps the values open. True words too with neighbours. I also don't want to get in trouble waking my daughter up if she's alseep :D

A very comprehensive review of this module. I have a 2020, C43 Cabriolet, so I’m thinking this may suit very well. However, can you confirm : “ In comfort mode,( emotion start up) valves are only open at 70% until revs hit 3000 then it’s 100%. With the ASR,.. valves are open 100% from start up and all through the rev range and in all modes ?” Thnx

[@ABAUTOAMG]

Hey, thank you. Yep with the module fitted it will force the values 100% open for startup and driving around. It remembers it so car always starts up with them open. You can put it in stock mode also at a flip of the button. Great little device.

[@umz9564]

great video but I have got a question , Can you fit this module if car still under mercedes warranty ?

[@ABAUTOAMG]

Hi Mate. No problem this should not void your warrenty. Warrenty is only void if the mod directly causes the problem that needs fixing. Theres not really a scenario where this would happen with the ASR module. Some of these hook up with your CAN-Bus for more interior button intergrationwhich could leave traces but luckily this module does not connect to the CAN-Bus. So it's the safest one as far as warrenty goes.

[@robbieenglish171]

Another great via ABAUTO 👏 your videos contributed to me getting a C43 back in September and now you are making me think about mods! Could you possibly do some noise tests whilst driving on the open road with a go-pro on the back of the car? Keep up the good work on the channel

[@ABAUTOAMG]

Ah thanks! Glad you've been enjoying the vids. Mods are fun! :) Absolutely I will try to make some more drive videos!

[@lavrans00]

What controls are lost when connecting the asr instead of the original leads? I suppose they're not connected to the centre-console switch, since it still alters the sound after the install... Then are the original leads related to throttle input maybe, which is subsequently trades away throttle-exhaust control over to the asr key-fob?

[@ABAUTOAMG]

There's nothing lost if hooked up correctly. All the cables are still connected the ASR module just sits in the middle, bit like a junction box. So everything is hooked up and still working just the module can tap in and bypass a few settings. I'm not an electrician so I may not have described this in the best way but as someone with first hand experience using this I can assure it all works as normal. Hope this helps! If you have any more questions I'm always here to help. I am also doing a free ASR module giveaway soon for my subscribers.

Hi mate great video! I have a 2017 c43 and get up stupidly early if the asr is on mode “2” would the cold start be a bit quieter? As it could wake the dead at the moment! Love the car!!

[@ABAUTOAMG]

Hi Daniel, quite the opposite actually! The ASR module remembers the exhaust flaps are open when you turn it off so you will get even louder start ups because the exhaust will still be open if you leave it on 1 for example by mistake. Leaving it on 2 would be the same as normal stock since stock keeps the values closed on startup.

[@nickedwards4787]

Hi ABauto. Just wondering if you could offer advice. I have brought an ASR module for my 2021 C43 which has the switchable PE fitted. It seems to be working but I have noticed the valves can be heard switching and moving periodically when the engine is not on e.g opening the boot or doors. Does the one fitted to yours do that? Starting to think I haven’t fitted it correctly. Also not convinced it remembers the previous setting.

[@ABAUTOAMG]

Hey Nick, Sorry to hear you are having some issues. What you describe does not sound right at all! Mine only opens and closes the valves when the engine is running and it doesn't interfere with the boot, doors etc. It should also remember the previous setting so if you have them open they stay opened forever until you press the button again. Have a look again to make sure the wires are all connected up. I have a separate video here with a walkthrough on the installation. kzbin.info/www/bejne/rZXFYoh7mK2qiNE Hope you get it sorted mate!

[@Zeke_91C]

Considering this mod. Qq: in your opinion, does it make the idle sound in S+ noticeably louder?

[@ABAUTOAMG]

Hey, It's only a slight difference on idle the biggest difference is it's a bit throatier driving a low rpms. Overall it's not a huge sound upgrade so it wont blow you away but it's still a nice little boost. One other thing that I like is that when changing drive modes back and forth from sport+ to comfort you dont need to keep pressing the exhaust button everytime. It's nice that it's always on if you like driving in comfort with the values open.

[@Zeke_91C]

@@ABAUTOAMG thanks! That’s really helpful. See what I notice is that when I do an emotion start on my c43 the idle sound is very loud immediately, and then 30 seconds later the idle sound quiets down even though it’s still in s+. I assume that’s the valves closing up again until the car is driven in 1st gear. So does the mod enable the idle sound to stay just as loud continuously until I start driving? Not sure if that’s too difficult to answer but appreciate any steer you have!
