O2 Sensor Question

[webng]

I've recently installed a JJR bellmouth dump/front pipe on my RB25DET S2 Stagea. The O2 sensor doesn't screw all the way in the new pipe, about 2 whole turns or so more. It's tight though, so i'm pretty sure there's no gas escaping. Is this a problem? i.e. the sensor doesn't go all the way into the opening? Any ideas if it's worth fixing? Maybe an exhaust place can make the opening bigger?

can you just drill the hole in the exhaust bigger, try not to damage the thread for the sensor though.

or file it out.

Don't know... The hole/thread just needs to be a smidgen bigger i suppose.
