Does the resonator have to be removed when installing the CT Icebox as in, taken out after the installation is complete?

 

The resonator has to be removed before you install the CTE Ice Box.

 

Thanks but does it go back in once its complete? Basically I'm asking if the Icebox is as quiet as you say it is with or without the resonator?

 

resonator doesn't have to be removed.. mines still in and the ct icebox is in. Maybe thats why my screw popped out from back pressure?

 

The resonator stays off. It's quiet without it, although it is noticeable at lower RPMs while trying to give it a lot of gas from my experience. If you take the CF lid off the box, you've basically converted to a SRI (noise and all).
