2002 EXiS is just awesome - I've owned it and loved it more than any other car! But Turbo is the king now - mighty fast in stock mode, and considering that its a Turbo, there is no end to how much it can be tuned.
I was myself considering Injen intake, some catback and a chip such as Hondata Flashpro, but for now am satisfied with the stock Turbo acceleration. Also, if I upgrade the Turbo then my CL9 will feel boring and I just don't want that
