I'm installing headers and an off road H pipe on my 87 GT. The H pipe has holes for the O2 sensors. My question is will I have a problem with the O2 sensor reading being off since I won't have catalytic converters? Will it cause a air/fuel ratio problem? Will it turn on my engine light? If so what do I need to do to make it right?
Thanks

nope, cuz the o2 sensors are before the cats if I recall

 

...You'll be fine! should sound good, go enjoy!

 

No problems here. As was mentioned the O2's are located in front of the cats so the computer won't know the difference. I've had my o/r h pipe on for over a month now and it runs great.

 

The only thing that changes is what comes out the tail pipe, or dumps if you're cool
