Any recommendation for a bolt-on muffler that sounds good (or any bolt on muffler). Appreciate it.

Likewise and will be orderering a set for the 4Runner soon. Only added a bit of time to my tire rotation

I have the Carven dump and I really like it.

I saw this and was interested because of the price, but not really confident in dumping the exhaust before the axle. Do you smell exhaust in the cabin in traffic? Is there a lot of drone because the exhaust empties under the rear seats? Does it pass inspection in TX (I know that part won't matter in 2025).

To your points:
  1. No, never have smelled any exhaust in the cabin, either driving, cruising nor sitting still for any period of time. I've sat still while idling for over 15 minutes before, and even with changes of direction of a breeze, no smell.
  2. Very slight drone when coasting down hill at about 15-20 MPH, but not annoying. No drone while driving at highway speeds.
  3. Can't say anything about passing inspection in Texas, but not an issue in CA, and if it passes in CA, can't see why it wouldn't in TX! Need to be sure we have the catalytic converter and a muffler of some kind.
  4. As a note I DO have the factory muffler, but NOT the resonator.

Haha, very true. In 2025, there will be no inspections in TX anyway. So moot point I guess.

Do you have this one?

No I don't.
After jacking up the resonator and tailpipe a couple times going through rock gardens, I had a local muffler guy cut off the resonator just past the muffler and weld in a short down spout, slightly pointing out to the side.
So far been quite pleased!

Link for known-functional parking sensors for 2010-2013. I successfully used this to replace a bad sensor in the front of my 2011.

Anyone know of an aftermarket part for the 2021? I'm chasing a parking sensor issue on mine and don't want to pay $$ for OEM Lexus; otherwise they'll just be off indefinitely. Wife likes 'em though so the search continues...

Allegedly the dealer may warranty service but I really hate dealing w/ dealer service departments. It's a 21 w/ 30k on it... Hmm.

Have you looked at the FSM sticky thread for a part number: GX 460 Manuals
Then try a search with that part number. Also, Bell Lexus (Arizona?) is usually the cheapest for any OEM parts. Most everyone on this forum swears by them.
 
Hey awesome list! Just made my build research a lot easier :) I came across this Roof Rack, that I never heard of before and from what I researched they do quality gear. I think I am going to pull the trigger on it soon, once I decide which configuration to choose. Toyota Overland Roof Rack
