1992 recommeded upgrades?

Hello, i have a 1992 GMC sierra 1500 extended cab with a 5.7. I was wondering what some good performance upgrades are?
i just installed a Flowmaster 40 series and love it.

if you have anymore recommendations please let me know.!

hey i have the exact same done to my truck and i was told. throttle body spacer, exhaust headers, hi-flow cat, and a intake manifold will really wake it up im not sure how far u want to go but thats my future plans for my truck.

Headers and Intake manifold don't do much good with out upgrading the cam.
