    Y-pipe question

    just got my SLP y pipe in today and i noticed there are 2 holes near where the y pipe would connect to the headers (one on each fork of the y about the size of a penny) are these for some sort of a senor? i'm trying to decide if i wanna do this install on my own or have it installed and i've never done exhaust work before.

    For the 02 sensors. Did you also order 02 extensions?

    If you plan on running headers, they will move the 02 sensor further back. The extensions are needed to plug them in.

    If the O2 sensors don't move, then no.
