Not bashing, but technically speaking the OEM x stuff is opitmaly sized for our turbos and plenty of flow. If you want a better uicp buy a used depo racing upper hotpipe to complete the x uicp.. That stops the flex in the rubber line. But 3" IC pipes, wont add power until youre at the BT stage, and i think even then its not really needed. Money better spent on an ETS 3" ic, which will lower temps even better than the x ic..
