if you go with a SVT header you should upgrade the exhaust. use your own judgement on what brand to go with or even look into getting a local muffler shop to fabricate a custom flexpipe back exhaust for you. typically it costs over $300 for a bolt on exhaust. i had a local shop do mine for $100 not including the cost of mufflers. i personally like the dynomax 3 chamber mufflers that autozone or advanced sells.
the K&N filter just flows air better than a typical paper filter. you wont get a huge power gain from it but its something. there just isnt really much power to be gained at all from intake upgrades with the focus.
focus-power P&P head $1100
focus-power DIY turbo kit $1495
