New to the board. First let me say I love my Crown and hate it's lust of gas. I'm getting 17.5 mpg and not a whole lot better on the highway. Anyway to get better gas milage? I've heard to get dual exhuast, cut off the bottom of the air filter box to expose the whole filter and even going as far as gutting the cats. Any suggestions? Should those work? Are there any other economically sound improvements to consider? Thanks
