I noticed DS2K was the only one with aftermarket wheels, could running a bigger and heavier wheel contribute as well to his low #'s? Regardless, great to see some dyno numbers from the IS-F! 400+ whp
That might be the case, but who knows... the other thing that happened was they couldn't clap it down too tight in the rear because my car was pretty low already and they were worried about the wheels rubbing.... so between the two it may have something to do with it, but it's really all just speculations at this point.
This just goes to show that the stock engine has more to give with just basic bolt-ons. I'd imagjne that you could walk away from some vehicles that a stocker couldn't. But I've gotta ask: What are you guys going to do when it comes time to smog your machine? I was actually thinking of Joe Z's exhaust but without the secondary cats, it won't pass visual (Southern California.) I asked someone who has built many exhaust systems for me in the past and he said "don't do it" due to the newness of my IS F. He thinks it may affect warranty. What say you?
When I picked up my ISF within weeks after driving it there was an exhaust leak in the stock exhaust, and the intake was not put together correctly.. the reason for this being that the previous owner did not put the OEM intake/exhaust back together properly... and this indicated tampering of stock parts, which were not covered under warranty so the repair came out of pocket (although the used car dealer covered this). Everything is back together again like it was from the factory, so I am now covered. But just a glimpse of what I had to go through at the Lexus dealership.

The OEM mufflers certainly were not helping.....
Hopefully your re-dyno after a cleaned maf, new oem filter and re-installing mufflers intended for our system; yields you the results in par with everyone else who has had successful dynos.
I am definitely gonna pick up some Sikky headers!!!
You will love them! I haven't had a single problem with mine and i've put them through quite a bit over the past 17 months. (Several dyno sessions, drag strip and the track).
it would have been sweet to get an open air intake and intake manifold results in there too.
