where can I get stainless 02 sensor bungs?

[DaveR]

I have a Neon R/T the original owner gutted the cat on.
I picked up a cheap stock SRT downpipe and cat planning to swap it on, however since the R/T has a tubular header from the factory, the upper 02 sensor is in the downpipe, just after the flange and flex section.

So basically I'd like to purchase a stainless (I think the factory systems are 409) 02 sensor bung and have it welded onto the SRT downpipe.

Anyone know where I can purchase such a thing?

This is where I got mine.
