Im sure this has been asked and gone over a million times...........I have searched and searche but still cannot find what I need. I need to rejet, I will have the airbox and ai removed of course, pod filters, and I am running the stock "mufflers", that I have cut in half removed all the crap and welded back together. Any suggestions? Thank you!

what year? what displacement?

you may need a shim or two, maybe a needle change or a 3mm slide.. there is more to it than just the jets themselves.

It's pretty likely you'll need to richen it up through the whole throttle range. I'd start with 135/42 jets, a shim and 3mm slide. That should put you in the ballpark.

K&N pods 142-145 mains, UNI pods 150-152 mains and a shim under each needle and DNA pods 155-158 mains with a shim under the needles. If you go to 42 pilots, forget the shims and reduce the mains by 1-2 sizes.
