O2 Sensor in catted y-pipe Hey guys i may sound dumb right now but i am looking for a catted y pipe to run from pacesetter headers because unfortunately i live in an area where i need to pass emissions. Do you guys know if i need the O2 sensor on an aftermarket y-pipe? Thanks.

The front 02 sensors are definately needed.
The back ones aren't. They're just there to make
sure the cat converters are working.
Most people just get them tuned out.
TSP makes a good catted y-pipe for pacesetter headers.
I'm not familier with the inspection / emission tests
in your area.

The front 02 sensors will plug into the headers.
I don't think that the TSP catted y-pipe has rear 02 sensor
bungs because most people don't use them.
So yeah, I guess if you wanted to use them you would have
to weld the bungs on.
