any recommendations for a 5.2L power boost?

I run around in a 95 GC Limited. I never did anything to it except a suspension lift and 31x10.50 tires.

I would like to know what options I can take to help it gain more power other than the obvious Intake and whatnot.

Are there tune-up parts that I could use when I tune it up for the summer? Oil Cooler possibly?

I plan on getting new exhaust from the manifold to the tailpipes, what would be a good system to use, I like a bit of a growl by the way.

any help would be great
