There is a Cat on the header where your O2 readings come from and there is a cat on the frontpipe. You can retain that second cat on the frontpipe, by purchasing the catted frontpipe being offered by Invidia here.
On a side note, Jeremy is off to the dyno to get some numbers on the N1 cat-back we currently have installed and runs with the frontpipe as well!!! Should have results and video clips up tonight |
Great news! Are the tests with/ without the catted front pipe? Perhaps both?
Edit: testing with "catless" front pipe. I'm asking because i am interested in the catback + catless setup. Hoping for an over pipe + header in the future.
