Pay no attention to the ignorant comments by dwcopple and overkill.
I am an expert on these cars - they have no clue here.
Well SORRY Mr. Expert! I didn't realize my knowledge on cars was excepted from this particular model
Are you honestly arguing that the intake won't be louder with the resonators removed?
Because, while I'm obviously no match for your clearly vast and superior knowledge on this particular car, I've removed enough air silencers from vehicles in general that I'm going to argue that you are out to lunch here.
That being said, I'd LOVE to see some before/after dyno results with the silencers installed and removed. Because I bet the noise increase is bigger than the power increase, particularly if the 2HP cited in the OP is accurate.
I'm not arguing against pulling silencers from the air intake tract (the Expedition had a similar scenario with like a 1" horn feeding the airbox that is now a 2.5" piece of pipe) but they most DEFINITELY make the engine SOUND more "woken up" than it actually is.
