Putting on some Long Tube Headers and "off road H pipe" on my 2008 GT CS and I wanted to know if I need to use O2 sensors on the headers and the H pipe?
There are fittings for both like the stock manifolds and stock H pipe. I know I will have to re tune , but didn't know if I needed all 4 sensors. Haven't had the car too long and I have some other mods (K&N CAI and a throttle body spacer ) and the car came with a hand held tuner with 2 different tunes so I will be going to the Dyno and want o be sure I have what I will need.
Thanks
