GX 460 Exhaust
Picked up a 2022 GX 460 Luxury recently and am thinking to change the exhaust.
Anyone have experience with MagnaFlow? https://www.magnaflow.com/products/19544-performance-exhaust-magnaflow-overland-series-cat-back-performance-exhaust-system
The road noise and interior sound of the 22 Lux is super quite. Wondering how loud this in in cabin.
Any small performance gains too?

Honestly don’t bother. These vehicles are nothing but a huge chamber that enhances noise vibration. You’re going to get drone no matter what you do to it and no matter what others have said or will say. I kept the factory resonator on and just changed the muffler to the largest magnaflow I could find just for a little noise and it still has drone and yes it is annoying. So much so I’m putting the original factory muffler back on.
Also you won’t get any performance gains out of a cat back exhaust change. If you don’t care about noise concentrate on researching and changing the exhaust headers. That’s where you’ll see some performance gains. These aren’t sports cars so don’t expect much more than what came from the factory unless you drop $10k+ on a supercharger.

I did think my magnaflow exhaust sounded excellent in the beginning and now, yes I hear droning. I will say my hearing has changed over the years as well.

DIsagree, my Magnaflow Overlander system doesn't drone. I hear a nice mellow V8 throb on acceleration but very little at cruise. And the high clearance tailpipe is great if you are going off road. It's perfect for me since I like to actually hear my engine doing its thing.
Magnaflow makes a big deal of their "anti-drone technology" for this system, whatever that means, but it seems to work. And it appears that neither of the above posters have the Overlander system.

Yes ... drone is a major consideration ... will drive one insane if cruising at highway speeds in a range where this noise amplitude occurs ... with some being so bad, it's like being in a torture chamber. Borla invests significant engineering effort in eliminating drone for each specific application. They apparently design and manufacture TRD cat-back exhausts for Toyota. I have one on my FJ Cruiser ... and no different than the multitude of Borla cat-back systems I have installed ... the sound is impeccable ... commanding but not obnoxious ... best described as sophisticated noise ... with absolutely no drone at any speed. Unfortunately, Borla does not make a cat-back for the GX460.
Maybe Magnaflow has advanced ... but my past direct experience is that their systems sound like they belong on a 1970's El Camino ... great for an American V8 ... but IMHO not quite fitting for a Toyota / Lexus.

I had the Magnaflow Overlander system installed as well. At first it was beautiful.....nice rumble and life was good. Then I helped someone move from Baltimore to Philly and on the ride up on I-95 everything was fine but on the way back with an empty cargo area the drone was unbearable. I had the system removed a few weeks later and it is now sitting in the corner of my garage.
So in my opinion if you tend to drive with the cargo area full of gear or locally (sub 60s) you will probably love the system but if you do a lot of highway/beltway driving and are sensitive to drone think twice.

To other posters comments ... many cat-back systems are designed for fitment and for exhaust tone ... with absolutely no engineering effort or evaluation into measuring and addressing how the generated exhaust sound frequencies will resonate with the surrounding chassis and body components. That requires a significant (additional) effort to eliminate any drone that is coming from these secondary vibrations ... hence the higher price tag.

Interestingly, I have this issue with the stock exhaust at the exact same rpms on my 2022. I even feel it through the footwell, steering and shifter.

That's weird. I wonder if one of your engine mounts is bad? Shouldn't be this soon of course, but stranger things have happened.

Have your muffler shop fabricate (or buy) a BRANCH CHAIN RESONATOR for a few bucks! It will cure any drone you have! I did it on my 300ZX, Tundra and LX470…! I plan on adding MagnaFlow to the GX460 after I buy wheels… & I’m getting BCR added as well!

Not necessarily, although I would expect it to be somewhat evident at startup and during revving at idle.
Just trying to think of something that would affect all of those systems, don't think exhaust would do it.
