PPE Headers are showing gains of 17whp & 4wtq for the RCF based on what I found online on this forum
American Racing on the other hand are showing gains of 24 WHP and 16 wtq of torque just with Headers
with FBO (exhaust, intake, tune, headers) ARH are claiming 59whp (info obtained off their website)
They do have bigger primaries which may lead to more power? I'm not sure but that's what I found from researching online .
I do plan on hitting the dyno next year. Will keep you guys posted once I get it done.

PPE headers all day. Get them ceramic coated if they don’t come like that already. Best headers ever made for the ISF. I heard complaints about Sikky’s headers and I’m glad my F came with the PPE’s.

this sound clip is without resonators (Headers, high flow cats, after market mufflers by cortek which is similar to borla)
No issues with the install other than the o2 sensors that needed to be replaced which is common. Also, I got the RR Racing engine mounts installed at the same time, and would highly recommend them.

Dont qoute me because I may be wrong, but I think RR tried headers with bigger primaries and didn’t see a gain. I can’t find the thread anywhere. The thread was started buy a guy asking about running bigger exhausts and throttle bodies. His attitude was bigger is better, and RR disagreed with this platform.
My car was stock originally. My first mod was the cat back following by the intake and then tune....headers came last and I really wish I did headers first .... Best upgrade 100%

After market Headers HP gains seem higher on the ISF than the RCF and that's probably why lexus made these changes on the RCF ...???
Here's a few photos to compare
Cortek x-pipe (similar to Borla)
ARH headers and their x-pipe which is all included

Fack, I didn’t realize ARH was producing stuff for us. I’m pretty happy with my V2’s but would definitely have opted for long tubes from ARH. I assume there’s no bolt up exhaust that mates to it though for our cars?
#44
Problem is I’m already invested in these V2’s and there’s absolutely nothing wrong with them. Any fitment issues with Sikky headers died with the original ones, that were also dirt cheap. If I ever changed them out, it would be purely for the sound of EL for something different.

Good info fellas I'm trying to dial this in for my LS460 NOT GS460 an I can't get a confirmation from the manufacturers. Which I understand. However it's worse when I can't find any official threads or get a confirmation from the guys on the boards/forums who have them to confirm. This is nuts... Someone HeLp mE!!
