Hey, i noticed you have the BBK headers.....what differences did you notice with them. We almost have the same mods so i'm am curious cause i'm wanting to buy headers. I have an 2008 Mustang GT/CS (california special) - K&N CAI, 62mm granatelli throttle body, Steeda under-drive pulley, custom X-pipe, IMCO cherry bomb mufflers, and a custom dyno tune....just wanting to complete the car. THanks
