Rather than cutting into the oxygen sensor wiring and installing an electronic version of the MIL eliminator, it's also possible to use a mechanical version.

This CNC machine high grade stainless adapter will allow you to change the values which are read by the secondary oxygen sensor.

This eliminator can only be used on the post car oxygen sensor.
Using the eliminator on the primary oxygen sensor will cause erratic engine behaviour and might even cause engine damage!

You're not allowed to run decat pipes on public roads. This product is intended for test / race purposes.
