yea. I've talked to an have been in hard core contact with the owners of several build shops an tuners around including PPE,JBA, an Flowtech. It seems as if JBA is the closes ticket but nobody's willing to take the leap lol except me. I'll keep you/youz posted. Because #I'm doing it period. For me its really a fitting issue..as anything will flow better than stock number 1, however I'm going TT like right away seriously. So initial performance of High HP an TQ I'm not shooting for because it's a TT set up. Im very Tempted to do JBA because of the hype from @dirtydeeds
Also, if you do a twin turbo setup, who is going to tune it? The most important part of ANY F/I build is the tuning. Without the tuning to tell it what to do, it's just a bunch of parts.
Are you building the twin setup or is a shop doing it? By the way, when you typed in TT, I thought that you were talking about a twin turbo setup, but if not, then Please disregard my comments.

The LS and the ISF have the same block so why wouldn’t the PPE’s bolt up. The factory headers even look 99% the same. There could be some steering rack or flange clearance issues but it shouldn’t be too far off. A GS460 member had PPEs and said they only needed mild modification.

what did you think of the spacers for your exhaust? Did they satisfy you?

Bought my LS 460 with secondary cats, resonators, and rear mufflers removed. Factory rear mufflers had been replaced with two short straight-through glass packs.
The car had hideous drone at 1,200-2,000 rpm (right where the car spends most of its time). Wasn't too bad above 2,000 rpm, but below that awful. The car would vibrate when drone was peaking at ~1,500 rpm. Added to that, the exhaust note wasn't very nice, had loose cackly sound, and was really loud. Wake-the-kids-up loud.
I found some factory resonators from a wreck. Had them welded in and, while the boys were under there I had the crossover removed (car now has "true duals"). Drone is GONE. Super quiet at cruise now, with a nice v8 burble when I get into it.
IMO anyone who wants a louder exhaust should leave the resonators in place. Toyota knew what they were doing there (surprise surprise, the resonators stop the resonant frequencies that cause drone).
My 2c.

You can get rid of drone by installing some J-pipes on the exhaust. They are also know as Heinholz chambers. If you google them, you'll see how they work because google can explain them better than I can.
They do work though because the exhaust on our Sunday/Funday car has a 3" stainless steel setup that has no mufflers or resonators in it behind a V8 and there is Zero drone with that.

Our V8's sound amazing!!!
I was honestly surprised myself! You have to hear it in person,
No resonators, my mechanic told me to try the setup with the muffler delete, if more is needed, He would take of the resonators. The sound is perfect. No droning so far. I am loving it.

Wait, so you took off the resonators also? I was thinking of deleting my mufflers also on my 2013 LS460. If this is the outcome i would definitely do it now! Sounds mean!

I’ve been there and ended up putting the resonators back in 👍
