For $500 I'm going to buy a set of coated Flow Tech headers & uncoated Y-Pipe. Do they sell them without the o2 fittings? I think I'm going to get rid of my cat's. I'll just buy some o2 simulators. Thanks, Fred

I saw this on another board. I am not the one who emailed them I just copied and pasted this from the other board.
Many of us have questioned why flowtech lts look the same as Hooker LTs in pictures, and wonder if they are the same header..
this is an email response that I received from one of Hookers tech support and the questions that I asked..
Questions::
What is the difference between hooker headers and flowtech headers besides
flowtech being $250.00 cheaper?
Which brand of highflow cats do you recommend for your header/y-pipe
setup?
Once installed how much ground clearance does your headers leave?
ANSWERS FROM HOOKER TECH:
The Flowtech headers will not have as good of weld quality or bend quality and will also have a three bolt ring instead of the slip fit connection for the y-pipe. We do not reccomend one brand of cat over the other, you will just need to do your homework there. These headers hang down about
3/4" past the rocker pinch weld.
Thanks

I work at Advance auto parts and I called Hooker about these and they said that they wouldn't be available til the first of March. They also told me that the the flowtechs didn't have provisions for A.I.R. They never mentioned the collectors though. I want to see some pics when they come in because these are the headers that I'll most likely run on my Z.

It looks like they have the 3 bolt flanges.
