CVF CATTED DOWN PIPES

[Dirty_3xploder]

I installed high flow catted downs from CV FAB. I am getting check engine codes after a few key cycles. I am assuming its bc i did not install o2 spacers on them. Ive looked up videos on this and from what ive seen spacers are only required on the non catted pipes. Dose anyone have any facts to this?

Definitely put the de-foulers on. We put them on mine, and I have the catted downpipes and never threw a code.

Put the spacers on.

You have to put the spacers on.
