Hey, I just ordered a 77 series K&N Intake for my 2004 4.6L F-150 xlt. I have a single input - dual output flowmaster system. Will installing the intake affect the way that my truck sounds in anyway? I've tried asking some people that I know but everybody has a different answer.




Thanks,
Stephen

 

you will get a nice growl from under the hood at WOT. and probably little louder exhaust
