Are they designed to last and work the same with out the Primary CATs there?
I hope to hear from our in house "Lexus Techs", since they have access to part(s) spec/data.

I still haven’t gotten the dyno emailed to me from my dyno session, I will have it up as soon as it is sent to me.
Toyota really puts a huge restriction on their exhaust manifolds; they all look the same for some reason and are all very very restrictive. I used to have a Solara back in the day, the v6 3.0 engine. Just a ypipe added 12whp, than someone later made a header system for it, and that made something like 40whp. Than there is the 2jz and the header I make for that engine, I was able to pull 25 whp out of that engine on an auto, the gains have been proven over and over on is300.net. Now looking at the is350, it has 11.8:1 compression, more aggressive cams, more displacement, and the same ****ty header design; I honestly will be surprised if it makes anything less than 30whp.

If minimum 30whp gains on the 350 turns out to be accurate, I WAS going to jump on them as soon as humanly possible, but since my car is in the body shop right now, that cost is going to delay my potential purchase of headers a bit.
