  1. (Non-Si)
    I didn't see one of these for non-Si's so I figured I would start it up to help everyone out! Feel free to suggest anything because I know I missed some stuff. I will try to keep up with it. Exhaust: Tsudo N1 Catback Borla Stainless Steel Section Borla Axelback Downpipe: Intakes: Injen CAI...
  2. Si Only
    With my older Civic, i found Spoon Sports and T1R to be my top favorites for performance. I used some Injen parts in the past, but i ended up selling them within weeks of buying it. What are your favorite aftermarket performance brands?
