Magnaflow cats being installed: need help!

[98GreenStallion]

SEE BELOW

Too make a long story short... I got stopped the other night for "loud tail pipes" The cop also noticed that I had no cats... so I have my car in the shop right now putting some "highflow" magnaflow cats on. Product #94006.
I cant seem to find any flow numbers on these cats... I bought them from O'Reileys for convienence... and they said they were highflows. Has anyone here had experiance with magnaflow products? ANy comments or info?

Thanks

EDIT: Just recieved call from mechanic, he will have to delete my rear O2 sensors in order to install the cats. So that means I will have no O2 sensors hooked up. So I will probably be needing the O2 extentions for my front O2's. Where and exactly what kind do I need? Most I have seen or for SOHC v8s...

02 extensions.
On summit there are some from BBK, that's what I am ordering.

As for flow numbers I have not found any anywhere.
My guess is that they flow better than stock. For what they cost I would also guess that they are not real high flowing.

How much were they a piece?

They were $75 a piece. I know I lost power due to them. Oh well, what can I do now?
