I havent seen anyone say they have done this. I took off the air filter housing and the "noise deading box" that is attached next to the air box and put a high flow cone directly on the air tube. The performance shop said its no heavier than an intake pipe made of metal and it deadens the sound just as much. Cost $35 for the filter. The old box and noise box approx 30 lbs or less now gone and the old box and noise box took away about 10-15 hp and i have that more with just the cone. I didnt really notice on 0-60 although i havent really tried it but on the highway flooring it wow what a difference. It is not any noiser either. I recommend you all doing it.
