Generally you're able to get away with the Gen 3 intakes, cat-back exhaust and EITHER HFC/TP or headers. When you run headers AND HFCs or Test Pipes, you'll be in a lean situation and tuning is mandatory.
That being said, most will go UpRev if they have Gen 3's, cat-back and HFCs, which will dial in the A/F ratio, and pick up 8-10whp..
