I am new to this forum as well as car tuning so dont have much experience with it, but am willing to learn. I have been looking online for performance mods for my 03 EX Civic but not able to find much. I already did an intake, Tower strut bar, short shifter, and about to look at catback systems. What other mods are available and are good for better performance?

 

Deja Vu' all over again. One post per question please.
