Magnaflow Exhaust on G550 and Fluttering Sound
Hi everyone, I had a muffler shop delete the muffler (under rear passenger seat) and they installed a 12 inch magnaflow exhaust on both sides with AMG tips. It sounds much deeper and more aggressive than the oem exhaust on my 2009 g550, however when I decelerate or anytime the revs drop I get a fluttering noise. I don't like the sound, and the muffler shop can't seem to figure out what the problem is. Has anyone had the same problem and what is the solution? Thank you!

I'll take a video clip once I get home. The G550 has a muffler under the rear seat and two resonators on each side of the car where the exhaust exits. They deleted the muffler and the resonators were replaced with magnaflow mufflers.

Got it, I see that you have a 2009 based on your username block. My 2020 G550 has 2 mufflers that I replaced with G63 mufflers thus the reason for asking.
