Im looking at buying a set of headers and running a whole new exhaust but i dont know how the o2 sensor will work. Im looking at running flow tech longtube headers into a H pipe to cherry bomb extremes through a 2.25 pipping at 45s into 4 inch tips out the back. But how would the 02 sensor work

 

you should be able to put the 02 sensor in the H pipe

 

Alright, thanks!
