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
Looks like Kooks mid-lengths have been used with good success. THREAD.
If performance is the only desire and not sound .......
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?
As for exhaust, does yours have the Extreme exhaust already?
