Hey all, I have a Ford Explorer Limited and everything is mostly stock except for my drop in K&N Airfilter. What I want to do is add power and growl to my baby, can you guys help me?!

1) I am looking at this, it looks pretty good, and I think it will add a superiour boost over my present K&N Airfilter! True or False?

2) I am also looking at these headers, if these are no good, please tell me, I want the best for my money, can anybody suggest some good headers?

3) Look at this cat-back system made from Borla, looks pretty good, anybody have any thoughts or feelings regarding this product, does it add growl and performance to my car?

4) I am also looking at a SuperChip, I have heard from some people that it will screw up my 4x4 Control Track system, cause I guess the 4x4 system depends on the computer! Anythoughts?
