I need to know if I use an aftermarket header (Megan Racing) how do i install the O2 sensor. Will it effect my main computer in the car?

Hi mbocox,

When after market headers are used, you have to drill a hole and weld a nut for holding the O2 sensor onto the header.

If the location of the O2 sensor is set correctly, it would not affect anything.
