I'm currently looking into any and all ways I can improve throttle response and power in my Aveo. I've heard a CAI and a Muffler upgrade improve fuel economy a bit and wanted some recommendations on mufflers that are worth a damn. Additionally, any general tips on improving fuel economy. I know the simple things; reduce weight, increase power, but anything special you guys know about? Sometime down the road lighter rims would probably help with reducing unsprung weight.
Any help is appreciated.
