Got my car back yesterday and I'll give you guys the good and the bad.
The good: My car is running perfectly with no codes, CEL's or anything else.
The thing pulls like a monster around 3,500 rpm now. It didnt really make the car any louder just more of a deeper rumble like a mustang cobra. The before/after dyno runs showed a gain of 32 rear wheel horse. Pretty pleased.
The bad: Two of my o2 sensors didn't make it and had to be replaced. That cost me 400 bucks. My drifting to the right problem seems to be even worse now. Need a realignment badly. Ill check the posts on the parts needed to correct the right drift as well. I get a slight whif of gas now and then but its not too bad.. Will keep you guys posted...

32whp is chunky 
02 sensors(@$400) = geez man. Looks like it came out to be an expensive upgrade. I'm really hoping everything is clean and easy when i do mine
As for the drifting to the right, I still can't get a perfect answer. I did the alignment and still nada. Before I get my subframe adj'd, I'm def gonna take it to the dealer and make a stink. I find it crazy that for the price of this car that this cannot be handled at Lexus

Ran new Dynos last week with my new rear and modified mufflers. The results are almost a year apart, so really can't compare, but a good baseline in my mind.
Blue - Stock Exhaust Manifolds and Cats, Modified custom dual exhaust with glass pack resonators, X pipe and stock mufflers, Takeda Intake
Red - As above with PPE Headers and Magnaflow HiFlow Cats
Green - As above with new mandrel bent rear section and dual inlets into stock mufflers
I'm happy with the results, although I was looking for at least 390HP
Looks like the improvements come mostly at the top end.
I brought a friend up with me who also has an '08 F. He has PPE headers, no cats, a JoeZ exhaust and an Injen Intake. He had a run of 399+HP with smoothing set to 5. His other two runs were less spectacular because he was running lean and the electronics were retarding his timing.
Edit: To add new Graph for Friend's car compared to mine. He seems to be breathing better at the top end, above 5500 RPM.

^^^^Yes they do, but not as a matter of course. If you want them to do it, they need to have a free bay, and the time. You'll need to call them and arrange an appointment that fits both your schedule and theirs.

I cant wait to get mine done. Already set in a deposit and will be heading down there the last week of may. Ill be doing that and installing an intake. Just havent decided just yet on which one in regards to the intake.
Will be looking at a modified exhaust once I put the car away at the end of fall.

Hi guys,
Long time reader, first time posted.!
Been watching this thread for a while, and since we don't have any support here in Australia just yet ( PPE did come out recently and took some measurements,we should have them ready mid way next month)
Im keen to know if what kinder base power i could expect with my F,
With just a JoeZ exhaust, and the Icode intake , Toms Air filter, i got a high reading of 372hp at wheels,
Then bout 6 months ago, we removed the intake and had it cleaned up , the guys tell me they cleaned up a few of the factory cast marks, and smoothed it out, refitted the manifold.
Last week i had it re dynoed in preparation for the headers to be fitted (to do a before and after comparo) and the power has dropped off.
A fair bit to be honest (353 hp) .
Both times the the dyno guy has commented on how rich it runs...and it would be better if you could lean it out a touch ..
Just a few ideas on why the power has dropped off.
i was going to PM just lowrideraz, but wanted to open this up as a few of you might have different ideas.
Cheers
