Lol... The video does not do justice, it's insanely loud with the valves opened. More manageable with the valves closed on the exhaust. More updates in the coming weeks as soon as my schedule frees up.

Did you notice any change in the acoustics of the exhaust or just volume?

Please tell me it is still livable to drive daily with headers and valves closed???
Can you do a drive by with valves closed and open? Right now, it seems too loud. Whether I open or close my eyes, I can imagine someone hammering stainless steel roofs (played via iPhone) but via laptop it sounds a lil better...
Just thought I would post up the pic Paul send us Tuesday of the complete set.

i remember in the RCF press release they had some kind of change on the headers. If the RCF header design is better than the ISF the gains might not be as large. Therefore it would be part of the reason of the power gain between ISF and RCF engines
I agree, I thought somewhere I read or was up here on CL about Lexus changing up the RCF header design for the 2UR-GSE improvements for the RCF
Like what 4TehNguyen said above, if a good majority of the HP improvement between the ISF and the RCF was because of better designed (better flow?) stock headers then I'm curious to see how much on the table Lexus left?? It'll be interesting to see what PPE equal length headers can do over the stock design for the RCF???
Amazing! I can't wait to see power increase from these headers!
FIGS please keep us posted on the coating options and when we can order. TIA!
We are taking orders now or you can contact PPE directly. Coating is bare stainless or Glacier black Cerakote. Paul should have the dyno plots etc up next week or shortly after.
The plus side here is that PPE was able to do equal-length which nets an improvement in power and sound unlike the IS-F which was too tight to achieve this. The RC-F has larger exits on the factory manifolds which is likely the improved design over the 2UR on the IS-F which neck down pretty good prior to the exhaust.

I wonder which exhaust they'll be pairing it with. I thought I read somewhere where PPE is crafting their own exhaust. Annnnd no that crazy exhaust with six tips doesn't count
