I’ve run into an issue with my AMG GT 63 S after installing downpipes, and I’m hoping someone here has dealt with something similar. After the downpipe install, I started seeing error codes intermittently. I took the car to an MB dealer, and they diagnosed the issue as a faulty lambda sensor. I went ahead and replaced the sensor, but unfortunately, the fault codes are still showing up.Has anyone experienced something similar after installing downpipes? Any advice on where I should look next would be greatly appreciated!

Thanks in advance!
