What are some ideas on increasing HP

[Sonoma SLS]

I have a 99 Sonoma SLS 4.3L and all i have done to it is added a cold air intake, what are some other things I could do without breaking the bank?

They do not carry parts for my Sonoma, thanks though

you could always finish your basic bolt-ons. You've started with a cold-air intake.. Now swap out the OE exhaust manifold (aka the header), and rip out the OE exhaust system for a performance one of your choice. Replace the cat to remain legal, but choose a performance muffler of your liking. My brands are usually Cherry Bomb, or Flowmaster when it comes to exhaust parts. Basic bolt-ons are inexpensive ways to give your toy a notch or two of goodness.
