96 sonoma performance

i have a 96 GMC sonoma with a 4 banger and im looking for some cheap performance upgrades that could give it some more horsepower.

just swap out the muffler/cat back for a performance one. you can also get a less restrictive air intake (ebay is the best bet). im not to familiar with the 2.2 but im sure there are other things out there.

yea i have the 2.2l and its a slug.
