I installed the ResoNix hood liner/sound absorber. The installation was easy and difference is subtle, with hood flutter now gone, but there still is about the same engine harshness/volume at higher rpms. Now I look forward to adding more sound absorbing material to the doors, as others have done. Toyota definitely skimped on this with the LC250, but I am confident that adding more sound damping will make a nice difference around town and on the highway.
