no its just the way you drive that changes aprox mileage. Most likely from all the stomping on the gas you are doing that lowered your approx mileage

If you don't floor it as much the header actually gives much better MPG, on the freeway with cruise control I was able to get around 32 mpg. That tank I got something like 470 miles out of it.

There's no doubt about driving styles. When I do steady state cruise control driving on the highway at 60 MPH, I get 35 MPG with my IS350.

Huh? Where did these numbers come from? Your dyno graph shows +31.4 wtq at peak, and +24.3 whp peak.

Nice, but I'm concerned about the sound. I modded my Audi up pretty far and it's exhaust was just a tad too loud. I want to keep my Lexus super quiet.

With stock exhaust, the headers do not change the sound much if at all. He's already posted about that multiple times.

Didn't the one with the video have aftermarket exhaust and intake as well though?

Sorry for the response. I just wanted the cliff notes version. I didn't have an hour to catch up.
I just read the entire 21 page thread.
What a read.
