I just bought a 2006 Honda Civic SI coupe 6spd manual. It does have the basic AEM cold air intake, and 2 1/2" exhaust. I am looking for other ideas for upgrades. What works best for quick acceleration. I am thinking, intake manifold, bigger throttle body, upgrade fuel system. I was also thinking of a performance chip or programmer. But do I need to upgrade stuff before getting a performance chip in the car? Please just looking for ideas and not criticism.
Thanks
