has any one heard or know any things about these intakes http://www.billscustomintakes.com/ seem like there well made and was wondering if anyone has one on there trucks right now?!!
i had one on my truck before the twins with a rdl turbo horn boy did it whistle and seemed like it flowed alot better then the stock setup imo
i think it was the 4" it was the biggest you could get before needing to rescale the maf sensor
mines very loud! love it. didn't notice any power increase over stock but the sound is awesome
