  1. I am new here, looking to put cold air kit and wanting to put headers on my car. Advice of what headers long or short work best on a Roush and cold air kits. Also any info on open an close exhaust, good or bad for this car? Thanks
  2. Not a S197 owner but .....

    Looks like Kooks mid-lengths have been used with good success. THREAD.
    If performance is the only desire and not sound ....... :shrug:

    As for CAI .... have you considered the ROUSH one? Tune included. THREAD. Biggest thing is to find one that is tuneable for any additional mods you plan.

    I guess my point is asking what header works the best will depend on what are your priorities? Some owners have listened to a lot of combinations and settled on one with more sound than power. Crazy huh? :D
    As for exhaust, does yours have the Extreme exhaust already?

    Good luck!!
