performance upgrades

I have a 95 2.5L 5-speed with a 3" lift and 31's. I'm considering the following mods and would like some input.

K&N Filter
Throttle Body spacer
Borla header?
high-flow cat
Gibson cat-back

If you have done any of this, let me know what you think. Is the header necessary? I looked at my exhaust manifold and it doesn't look like there are any major bends or turns that would really hinder flow? Not to mention that stainless header is pretty expensive!

I am already saving up for the gear change so that I can get my 5th gear back, but just looking ahead!

If I missed any upgrades that you feel would help (already took out the air restrictors), let me know. Thanks,

The K&N filter works well with the restrictors removed. You might want to consider a 4.0L Throttle Body as well as a 4.0L Throttle Body Spacer (PowerAid #310-510)
Can't give you the actual results of this myself as the TB is in transit as we speak. You could also do the 20 gallon gas tank modification.
