The first thing I would do is remove your battery and replace it with a Braille or other lightweight battery. They weigh 10-15 lbs depending on which one you get, that can save you 30 lbs or so.

How much are the Braille batteries? Do I need a custom mounting kit?

After that, weight savings gets quite expensive. Going to a single set of high-flow cats and headers can save another 25 lbs, and give you a few extra hp, but doing so can result in CEL error codes if not done correctly (I know this from experience).

Changing the cats is a no-go here in California on the non e-gas,the e-gas folks can get away with it.
