o2 sensor problem

[BRAK54]

just have a question. will having a test pipe, header and exhaust cause an early wearing of your o2 sensor

[talonXracer]

Not on there own, but if it isnt properly tuned then yes it can harm the o2 sensor

im running a stock ecu still.

well with the stock ecu and just some aftermarket exhaust stuff you should be fine....don't forget about the defouler on the secondary sensor with that test pipe, that is if you don't want a CEL haunting you at all times.
