Well the current numbers are in! In a nutshell I believe with the addition of the GESI cats combined with the new v2 headers yield about the same if not a tad bit more power than with the v1 headers and being catless. SAE shows the car is down only 6 hp, but UNCORRECTED the car is making more power than ever, even with slightly warmer testing temperatures. With that said, I don't have full confidence in the SAE correction factor this time around with temps being warmer and the humidity only being slightly lower and being hit with a .97 SAE correction instead of 1.0 like I had hoped to see today. So guys, I don't know how much this helps you, but I'm happy to see that my car is not down on power compared to before even with the addition of the high flow cats. I can only conclude that the new v2 headers are indeed superior to the v1 headers which already made excellent power. I do however wish I had not put the cats in so soon so I could get more of an apples to apples comparison, but at least now you know how the F will perform with GESI cats and the v2 headers. Any thoughts are comments are welcome as always.
I plan to get the RR Tune soon and will post results of that next.

Pole Position
Good to know the Gesi cats don't lose power! In the not to distant future they are on my list to get rid of the smell when your catless & FBO

So basically could be a +7 who gain from v1 headers to be and a -5 to -7 hp lose from going to cats....really don't know. But there is a gain, which is good!
Did Sikky install the high flow cats or you did?

Hey Caymandive, great way to post your results to the community. After owning the car for almost a year, I cant believe I missed this thread until today.
I'm hoping you do a rr tune results and share your findings. For me, I tried the rr tune and intake and was having some trouble making good power which was odd (I did not have the time to trouble shoot), then I tried the tune alone and it actually jumped 10-15 more horses, it's really strange how these cars behave. I do wish I had the time to dyno more unfortunately, I lack the time and money to keep dynoing, and had time to do only a few quick pulls on dyno so am keeping the tune in the end since it did make some nice power. I'm not sure why however on my testings I learned that a high flow filter (mine was apexi) and joez pipe added consecutive 5-10whp all around even the operator did not believe it and kept wanting to do more hot runs to see the numbers fall, but it did not. I didnt even have time to get the printouts, I will have to go back sometime on the weekend. Likely they were probably more interested in dynoing 1000hp gtrs than 400whp isfs
Again really appreciate you posting, I really don't see many posting information like this and reading the thread from post 1 is definitely worth it and gives some what of a starting point.

Given the extra few HP that the Sikky v2 headers are adding, you might end up with one of the most powerful NA IS-Fs around.

Drove up to RR-Racing today and met with Rafi, Simon and Anthony. Great bunch of people and I can see the passion in how they work. A big welcome to the Lexus community for sure. So while I was there we installed the intake, tune, air/oil separator and the USRS bushings. I have to be honest I did not expect to notice the power gain via the ole' butt dyno, but I can absolutely tell the difference. Also the bushings are awesome! Car feels more planted and sure footed and that intake sound....WOW! Sounds awesome!! I had a feeling it would be too loud and resonate like some of my previous intakes I've tried on other cars, but this one just growls and it's music to my ears.
Will drive around for a week or so and get scheduled for another dyno and post results. I then plan to start hitting the drag strip the later half of November and early December.
