    Well i've installed a cat-back exhaust and an aftermarket intake, i'm wondering what I can do next to increase my mpg/performance. Any opinions would be great, thanks!

    I would say go for a programmer or a custom tune. Lots of info about both on here, so do some searching around.

    i would recomend a programmer cause you can swap from fuel efficiency mode to tow/haul mode to performance mode. if you dont want that, go with either high flow cats, headers, mass air flow sensor, or larger throttle body

    I think doing everything mechanical like headers, then throttlebody spacer, high flow catalytic converters, change the fluids and then get a tuner so that you can get tuned with all your mechanical parts on it. Just my thought.

    i have them on line. i like them, but i have heard that if you go stock, that there isnt really much restriction on the stock cats when new

    I agree with him...this is basically what I am doing...building it up then get the custom tune to tie it all together
