Anyone know who makes the best headers that fit the stock ypipe?

 

look into slp maybe, not really sure if that uses the stock y-pipe even, personally i wouldn't bother and go with long tubes but if you have emissions they might not be the best for you...

 

I dont have emissions but I need to keep the o2 sesors.

 

Long tube header have provisions for the front O2 sensors.

 

You are the man 2000gtp! You have all the answers!

 

All emissions equipped headers will include the front (pre-cat) O2 sensors. You don't need to keep the stock Y-pipe. You can easilly add them to non-emissions headers. In fact, only the passenger side O2 sensor is on the stock Y-pipe. The driver's side sensor is in the base of the stock exhaust manifold.

 

I think you have them flipped actually. Pass side is in the manifold
