I just got enough cash to start modding my 02 tl-s. I got aem cai in it and i feel a definite difference of power, plus little power loss even with a full car. I want to keep it responsive and i heard that the edition of headers can kill low end power, i heard that exhaust is not even worth it, and pulleys and spacers just seem like they should be done last. I dont know what mod i should do next cuz i can only do one of them untill next summer comes since school doesnt allow work.

 

pullies = low end power. i would look into those if you want instant gratification. that or drop is my vote.

 

Headers are the best bang for the buck if you want HP.

 

Crank Pulley and enjoy
