you can delete your cats, its possible, you also are going to get a cel if you dont use a o2 sim, or turn it off with a tuner, i use livewire, but when top secret dyno'd their supra with and with out cats a hp of 8 was gained with out, thats on a 1000+ setup, so you may see 1 hp if any...

When i had my rsx i got a header that eliminated the cat, i got an 02 sensor eliminator and my car ran fine..in fact it ran alot better without the cat.

i make o2 sims for dsm's, eclipses/talons/lazers, for those who chose to not go stand alone but delete the 2nd o2, and its the only way to fool the ecu to think that you got one....
