Had purchased a CPO 2020 RX 350 with 31k miles. After being acquainted to the car around 1,000 miles later really noticed a drone vibration particularly around 1400 RPM. After bringing this up to a dealer they dismissed it, however the next dealer agreed with me. They replaced a section of the exhaust from the manifold to the muffler. This definitely helped tone down the vibration/drone, but not eliminated completely. About 60% better than the original. Looks like the rubber damper is a little beefier than the original to help with vibration. I have a 2023 ES 350 with the same engine and transmission as this RX and it doesn't vibrate at all thus my concern. All parts were replaced under warranty.
