I Need Info On O2 Sensors...

Hey guys, I was wondering where my stock o2 sensors are located, and where they need to be relocated to in a custom exhaust setup. Also, will I have to buy new sensors, and if so whats a decent price. Thanks

you won't need to buy new ones.

you will have 1 O2 in the collector of your exhaust manifold and 1 after the cat. if you have a shop do a custom exhaust they have to put the O2 sensors back in.

O2 sensors run around $50-$60
