Got the time to finally install my Headers on my GS I have had for about a year now. So much of a pita, that I forgot to take a pic up under the car of them installed. Looking from the top this is about all of a pic I could get from the drivers side looking down. They are ceramic coated and heavily wrapped with high quality Header wrap plus a wrap coating.
Picked a very nice increase through all the Rev range from down low to up top, especially with the D3 Performance Pro Tune. I love it! Next is the install of a Flow bench ported upper/lower intake manifold, and ported very slightly enlarged TB. Then the fine tune with the D3 Pro tuning software for the ECU.

Please keep me posted, If it wasn't for CARB this is what I would be doing, NA mods. Let me know if you dyno it. From what I have heard, Headers + TB+ ported upper and lower manifolds will get you over 300 whp. Of course, that is also dependent on the tune.
Speaking of tunes, how has the D3 tune been? Any reliability issues , or weirdness?

Will do. Although you have Carb there's lots of IS guys that still do the Headers and other on the IS350 in Cali still. Dyno with Headers, TB, Intake port, Tun actually makes about 320 - 330hp. I actually have a few other things added to that for performance.
D3 Tune is great. Zero issue and the Sport+ is connect to turn D3 Tune to Stage 3, on with Sport and Sport+. In Normal and ECO is a Stage 1 Tune. D3 Tune can even add 20+ to a stock car, and improve the normal drivability too. The torque and torque band in my GS is just so much better feeling now. Once I have finish all the Mods it will go to be fine tuned on the Dyno and get the numbers.
Changing the oil in my car, decided to inspect more stuff.
The engine air filter is a K&N, and looks like it's got a few pinholes in it already! So that will obviously go in the trash soon.
It's interesting that in precision work and clearances light passing by two objects is an absolute method of determining the width of a gap between them... maybe this should apply to air filters?
We'll see what the Blackstone oil lab says about the engine health. Doesn't burn any and was still at the scribe mark I made 4kmi ago.
The oil filter housing was insanely tight, so tight I had to use a breaker bar. I coated the seating surface with Neo-lube so it should come off easy next time.
Everything else looks good though, exactly what I'd expect from Toyota

Did you use the apprpriate oil filter wrench? Looks similar to this:
@jdr76 I know you wanna keep your car clean, but driving a GS in the rain is whole other experience. It's like driving a big comfy couch when in inclement weather. I love the fact that the glass never gets foggy, I don't even have to think about it. in my other car I have manually turn on the AC and heat together like a pleb 🤣🤣🤣

Indeed. I used to daily both my 15 and 19 GSs, which included all weather, even the snow. Working from home changed everything, and as we are now starting to go back to the office, I generally just take the truck, as it's already outside and dirty anyway.
I just spent the weekend in the snowy north. As we drove through intense wind, snow, and thick ice, I was missing my GS, though thankfully the rental car was solid and also had AWD. I started being thankful I wasn't in the GS when cars were sliding off the road and when the front of the rental kept taking rock hit after rock hit. Had I been in the GS, I would have pulled over and cried...
yeaaaaah I agree with you there. if there is gonna be snow, salt or sand on the road I take the trusty beater. I took a trip to Tahoe years ago and was missing the GS's power and fun thru the turns until I had to pass a Caltrans sand truck that was tossing sand against the cars in the passing lane...
