Ok so I have lots of questions! I curently have a cold air intake and cat back dual exhaust but I want more!!What is the better way to go?Headers (Long or Short? and what is the difference?),Programmer,or MSD coils with new wires and plugs? I have the 5.3 with just 50,000 miles.Eventually want to add all of these but stuck on where to go from here! Also, what are some recomendations on brands?
