No, it does not. The Draw-Tite Hitch item # DT73QR does not require you to drop the exhaust when installing it on your 2023 Lexus RX 350. I have linked the instructions below so you can take a look at them. view full answer...
Hey Shane, for your 2020 Lexus RX 350 that didn't have a factory hitch the trailer wiring that you honestly should have gone with is the part # C56217 which is for the versions of the vehicle that don't have the tow package. While your vehicle has the connector it's not active which is why it's not working as-is. Maybe Lexus dealer could activate the wiring harness but we don't have any info on that. view full answer...
