Need New Catalytic Converter and O2 Sensor

[emjlr3]

2000 Camaro v6 auto

Car threw a PO420 code at emissions.

Figured it had something to do with the cat and/or o2 sensor. i had put a new high flow catco cat in a few years ago (welded) but it seems its bad.

went to a shop, and $100 later my suspicions were confirmed - they are saying need new cat and o2 sensor.

since the cat is welded in, they are saying they would need to sub it out (which is dumb) - and the other stop says $880 for the repair, which I think is asinine.

i know a place i can get the labor done cheaper - so I was wondering if/where I should order the cat and o2 sensor from for the job - and what parts in particular i should get

btw I have a 2.5" flowmaster american thunder catback system installed as well

thanks for the help guys

ok so GVPerformance sells these convertors for pretty cheap

from what I remember, the pipe into the cat is 3", and the S pipe after the cat is 2.25"

so why are these cats 2.5" in/out or 3" in/out?

doesn't seem like it would fit to me...

also, since it seems that the gvperformance does not sell o2 sensors, where should I go about getting those?

Re: Need New Catalytic Converter and O2 Sensor

O2's you can get at your local parts stores. It really doesn't matter what cat you get because at an exhaust shop they will make a reducer for it to work. I would go with a 3' cause you may upgrade everything down the road. Do it once and not twice. Yes the inlet from headers to exhaust is 3' and I think your right about the 2.25
