Nope. It will make it run better, get better gas milage, but the newer cats are a lot better than the old school ones, so the gain may not be to noticeable

Looks like the go fast goodies are already getting to him!
That thing will be s/c with nitrous on the side before too long!

no no, almost with my T/A but not with this truck, to risky for me, plus the drag scene by me is dead, and i never have time to go to the track

Make sure that you aren't going to fail emmisions test with out cats. I am from Dallas and they put the sniffer in the exhaust pipe when you go for your state inspection.

They still visually look under the truck for your cats. You might have missed that part.

check on e-bay for the guys parting out ls1s. I found a set that way for $25. The only defect was a broken mounting tab that I won't use anyway.
