I just purchased a mac oryp for cheap to bolt up to my stock manifolds.....i was under the impression that i could just unbolt the stock ypipe at the intermidiate pipe and at the manifolds and bolt up the oryp. i figured i'd need o2 simms for the after-cat sensors

however, someone said something about front sensors...

can someone clear this up?

thanks

My front 02 sensors where attached at the front of the bolt in cats if I remember correctly.
