I have a 2018 RC 350 F SPORT. I would like some feedback on what brand chip/tuner and exhaust I should purchase. I am mostly looking for bottom end power/acceleration. I prefer the exhaust not be obnoxiously loud or raspy

This provided immediate acceleration and removed the lag in the throttle that was the only painful experience about the car imo.
Pedal Commander Throttle Response Controller PC55-BT for Lexus RC350 2015-2019
My favorite upgrade so far. no engine light and works perfectly, added it in 45 minutes.
I have an Invidia axel back exhaust and loving the sound, its not annoyingly loud, live in a housing development with no complaints.

So what tuner did you end up with?

Thanks for the link, regarding the chip and upgrades, there is a good resource nashvilleperformance.com/lbz-duramax-upgrades/ where you can find a lot of information about spare parts for this. I do the Best LBZ Duramax Upgrades for my trucks so that I don't have problems with engine overload.
