When you remove one (just one) of the restrictive stock parts i.e. exhaust or intake, you will see a significant gain. When you remove the other, you will only see a small gain. Just because a CAI claims 30 HP and headers claim 30 HP does not mean you will get 60 HP. When you pop the cork on one end of the engine, you really free up the other (stock) end to work better. When powerfreak swaps for headers next week he "should" see a 10 maybe 20 HP increase but no more. Whe I install my Vararam on my A6 I do not expect a 30HP increase because I already have headers and a tune. Hope this helps
