Let me start out by saying it was very easy the hardest thing was shaping the pvc to fit in the old cutout in the fender. My truck is a 4.6 and it really helped with throttle response because before this my truck felt as if the throttle was very delayed. If u have not done this I would highly recommend it.

 

I plan on doing this as soon as I get my truck back.

Did you remove the intake mufflers?

 

Do u mean the silencer and if so i didn't remove it because I have heard people say it is a PITA and does nothing but idk

 

think it the resonator on the side of the tube hes talking about

 

Does mine have one of those as its a 2001?

 

YES, it's inside the tube
