I just traded in my 2018 Q50 Red Sport and got a 2021 Q60 Red Sport. My Q50 was pretty much the base model. I went all out and got everything on the Q60. I have only put about 15 miles on it in the 3 days I have had it. I got the Performance Exhaust Package and love the sound and the responsiveness. Only issue I had was I could hear like a weird clunk today when going through a parking lot with some speed bumps. The dealership left the original huge muffler and the parts for the air intakes in the trunk. So I thought it was that maybe moving around. So I took it out and went and drove around and it still did it. So after some looking under the car the drivers side exhaust bangs against the bracket with the exhaust hangar on it. The passenger side is fine and snug but the drivers not so much. So I guess I will make a trip back to the dealer tomorrow. They did say this was the first one they had installed and sold so I don't know if they missed something or what but all the pieces seem to be there to include the rubber grommet the hangar goes into. So hopefully it's something quick and easy to correct. I don't know if anyone else has had the issue but thought I would post it in case someone else has the same issue and didn't figure it out yet.
