Yes, precats for SVT and SE V6 are the same, i.e. Bank 1 SVT precat is the same for Bank 1 SE V6 precat. Bank 2 SVT precat is the same for Bank 2 SE V6 precat.
Bank 1 precat is not the same for Bank 2 precat.

Not strictly true.
There are no significant measured gains from gutting pre-cats as far as I have seen. I have also done the mod on 2 V-6 Contiques. The only time I have observed a percievable gain is when the pre-cats are clogged and/or falling appart anyway & getting fouled. If your pre-cats are failing, it is a good free mod to get your car running properly again, but you'll need mil eliminators. If they're not failing, leave them alone.
For a gain in performance, get MSDS headers.
