I don't see how a less restrictive exhaust and filter would help.

Take my advice, dont mess with non standard air filters and exhausts, unless you have access to a wideband AFR meter it will never run properly. Honda knows best.
I agree with Grant-53 re. tuneup, it might help to advance the timing by 2deg (a no cost option and worth a try), and a small screen at an acute angle can add as much as 5mph to your top speed.
I don't think you will see much better than 100 miles per US gallon without some radical changes.
