Shame you didn't ask before you rebuilt the motor. The EJ22 heads work good on a EJ25 block, and Delta Cams wake it up even further. That would be your ideal way to go.

For what you have now, you can open the exhaust up, but the WRX can is no upgrade. What year is the motor? Are the heads single or dual (exhaust)port? Dualport heads accept any EJ25 exhaust header but have smaller valves and ports. The singleport heads are better, but nobody makes a header for them anymore. DIY, or mufflershop special.

Jay is right. Should have asked prior to rebuild. But... all is not lost. You can still add cams.($93.00/ea) from Delta. Also, a Perfect Power 6 piggy back will improve the maps and get you a bit more power. To fully utilize the cams and piggyback you should also add an air intake and improved exhaust.
