MVP 2jzge headers, will they fit 99?
It says on the MVP page that these headers fit 92-97 only? Is that because vvti? What would I have to do to make them work on mine? Im thinking they'll bolt right up.

All of those headers are all made with the newer VVTi 2JZ motors in mind(more specifically the IS300). Thus they have the screw in o2 sensors.

You're welcome. I've researched it a fair bit, and few people have particularly good things to say about N/A header upgrades on the 2JZ. I'd still like to try it out if I ever find a cheap one used, but the likelihood of being a worthwhile upgrade seems too slim to justify retail prices.

Yea I'm wondering if set up with a BFI if this will get you to around the promoted 17whp they say this will add. Although I already have aftermarket exhaust Im curious how much louder this would make it. I wouldn't want too much noise its already a lil beefy.

Other than increased noise levels, which many report as obnoxious, the main downside is loss of low-end torque. The advantage is the 8-17 HP gain, but that's mostly up high where it's rarely used.
The only reason why I'm still interested, given those significant drawbacks, is my application is on a car 500 lbs lighter than stock. I'm curious if the torque loss will matter as much there. Also, it feels like it revs freer with less weight holding it back, so the higher RPM gains might be more attainable.

Note : all 2JZGE engines regardless if it is VVTi or NOn VVTi have exactly the same intake and exhaust flanges used to mate the manifolds on the Cylinder Head . That means there should be no reason why that headers will not work in either engine .

SO this application is much lighter than stock? And Gerrb you're right I wasn't going to buy it for retail. I figured to get the HP gains Id have to do full exhaust and intake my plans were to do BFI and 3inch all the way back with my blitz nur spec dual pipes. What do you think about that setup in terms of HP gains and low end torque loss?

And yes of course you will notice a loss of torque, it will matter regardless of the weight savings.
