Is the new DR manifold helping O2 sensor issues? (Poll)

[MooreBoost]

For those of you with the updated Doc Race manifold with heat sinks, are you having O2 sensor issues?

I'm probably one of the few on here who has had multiple doc race kits. The new manifold design is better but I am still having problems. Getting about 15k out of NTK sensors

I have the older DR top mount manifold that's not one solid piece. It actually came with heat sinks. Lately, I've been having horrible 02 sensor issues. The car throws 02 sensor codes almost immediately after being changed. I think my issue due to the sections of the mani, connected by v-bands that feed the turbo and house the 02 sensors leaking. I've read that leaks prior to the 02s will throw false 02 sensor codes. Pic of one v-band included.
