Here's some info on the stock setup:

While the stock Tri-Y header flows really well, there are still gains to be had with full length headers along with a good tune.

Deleting the secondary cats should not mess with the warranty of the whole car, the exhaust maybe but the whole car no since they are not monitored. They will offer a better growl over stock and frees up about 5hp or so.

The only thing bad is the x-pipe in the stock system is at the rear of the car right in front of the muffler, that is the worst place for it. I have the ARH catless full system headers on my car. Beautifully made here in the USA and they correct the x-pipe by moving it towards the front for better scavenging.

If you want some decent bang for the bucks mods, here you go...

Untuned:

PRAY ported TB/IM combo
Roto-fab dry CAI
Secondary cat delete

Should pick up around 20rwhp.

Tuned:

All of the above
Long tube headers (catted or catless, your choice)
E85 flex fuel sensor kit
Tune

Expect to pick up another 40-50 rwhp or so. Should put you near 450-475 rwhp at that point.
