2021 E53 AMG Coupe
Help! E53 coupe Installed downpipe and my pops/burbles gone!!!
Hi Everyone,
I have a 2021 E53 Coupe, the already good standard pops and burbles in sport+ we’re great. I recently installed a project gamma downpipe (great quality downpipe). The moment I took the car off the lift it sounded awesome! Pops and burbles were working and sounding stronger and deep BUT NEXT DAY, POPS AND BURBLES COMPLETELY STOPPED HAPPENING!!!!
Anyone can offer help or suggestion why and what I can do to get my pops and burbles back??
Thanks!!!

Scan for codes and see if there are any because if there is a stored code it might cause the ECU to not produce them (as you know the pops and bangs are generated by the ECU by retarding ignition timing).

Might be soft limp mode. Too much air and the ECU is not going to like it. That's why you always tune the car if you're gonna do downpipes

basically you have to do a tune the car was in a mild limp mode that’s why it stopped the burbles
