Oxygen Sensors on OBD2

[BrutalB83]

Hey there, I've purchased a Megan header for my 97 Integra LS coupe, and right now I'm trying to decide if I want to buy a catback system or just do a muffler shop exhaust. Anyways, my question is, if I want to run a test pipe or just elimate the cat, will I have to get an 02 simulator? I've heard that OBD2-equipped vehicles have a sensor on the manifold and in the cat. Is this true?

it does but no big deal just make sure both sensors are in the exhaust pipe somewere and it will be fine

Yah ODB2 has 2 O2 Sensors, Some Test Pipes dont come with 02 Sensor holes, I know that the Skunk2 test pipe does,

Youll either have to get one with the 02 sensor hole already in it... or buy an 02 sensor bung and weld it on, or have it welded on ( muffler shop will charge u like 5 bucks to weld it for ya)
