i have the 1st set of O2s but got rid of the ones after the first set of cats. The guys who did the exhuast said they can get simulators to "trick" em. i wonder if that would help..

any theories?

do you guys have emissions in NV?

simulators are gay, just get new o2s. i get around 24/27 mpg. i gota big cam, 19 lb injectors,intake and header on mine.

put the cats back in it with the 02 sensors after the cat. dont screw with those simulators.

My F-150 gets about 19mpg on the high way.

There are no room for the cats, thats why i got rid if them.

Yes there are emissions in NV. Ive got a guy that will pass the truck so i dont care about that. they can fuck themselves cus i see cars that are smoking black crap all over the place and no one does a thing about it.

have you looked into a spun stainless steel cat?
