BMS Exhaust Bypass Module for PE (Facelift C43)
Hi guys and gals,
Just purchased and installed the BMS exhaust valve bypass plugs for my 2019 Mercedes C43 equipped with the Performance Exhaust.
I followed the guidelines off a forum member here. Left my car off for 10+ minutes, had the key signal blocked and unplugged the valves. Started the car with no fault codes or limp mode.
Valves are 100% open at all times. I highly recommend this product and no, this is NOT sponsored in anyway. Just helping out my fellow MB owners who are looking to save a few $$$.
Happy to help if anyone has questions.

@jhcole100 super simple to install. Took me about 15 minutes to install the valves.
Remember to do the following;
Lock car
Do not have your car key present while installing these as it will wake up the electronics
Have your car locked and sitting dormant for at least 15 minutes
Remove plug
Install BMS plug
Unlock Car
Star Car
Enjoy!
***Failure to follow the instructions above may cause limp mode***

Do you have any pictures of how and/or where to install them?

Thanks again Hillstrand!
I just installed the Burger exhaust valve bypass /delete plugs....After waiting 15mins for the ECM to fall asleep it only took 10 mins to install!
Driving around town it is slightly louder but not obnoxiously loud!
No more pushing the exhaust button on every start-up! (still have to push the stupid auto-start UGH!)
Starting up this morning the car sounded Absolutely Great!!
Anyone thinking about exhaust plugs should really just do it!
I think it is a great Bang for the Buck!
