im already planning for my mods to the car even before i get it. but since im probably going to be putting nitrous on it im thinking of changing the headers at the same time. is it worth that extra money to get some nice 4-2-1 headers?
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?
