k quick question, some of them say, single air injector, single oxygen boss, dual oxygen boss. What is the difference? Which offers the most flow. Thanks :D

They all offer flow. Not too sure on the Air injector, but the O2 bosses are for your O2 sensors.

[1NotSoBadAssBird]

so should I get a dual or single oxygen boss?

[SexySixer707]

What year is your car? It depends on your setup for your O2 sensors. It might not even matter because your ses light might go off with your highflow, but might not. If it does, then you would need a O2 sim.

I got a 2000, and Im slapping in some pacesetter headers and a hi flow cat very soon. I havent even touched my 02 sim. So should I get the dual or single boss? Or single air injector?

I hope your getting the coated ones. Anyways, not sure on your year, but you should get the cat with a rear O2 sensor. The pacesetters have the O2 sensor bungs in them, but for the rear it might not reach, hense the cat's single O2 bung. Air injector you don't need, but double check. I think that automatic's don't need it.

you want one WITHOUT the a.i.r. you dont need the o2 bung on it. you will most likely set off an ses light. your besy bet is to get a cat with out an o2 bung at all, and then just buy an o2 sim.

Agreed.

FWIW, the Catco CTO-6007 cat is very popular here. It has the AIR port. It just gets capped off for 3.8s. No big deal, but it's like 10 or 15 bucks cheaper than the same cat without it. ;)

should I get a wire extension for my 02 sim? Cant I take away the SES light Ill get with the new exhaust system with my Hypertech programmer?

[1NotSoBadAssBird]

k Im confused again :\ I should get the cat without any injectors or bosses correct? Then I need an 02 sim, and the 02 sim will plug into my headers right?

[98Camaro3.8]

O2 sim is only for the after-cat sensor. It doesn't plug into the exhaust, it just plugs into the car to make it think the sensor is there.

Oxygen sensors.
