O2 sensor help

[Steve's Chevy]

if you have an old O2 sensor that you dont want anymore, just break off the non thread part and fill it with weld. This is hand too when welding near a bung, so you dont get weld splatter in the threads.

ya , I used a oil plug for now and ordered the right SS plug from Summit.....be here tomorrow!!

I honestly don't know why the don't include a plug with this exhaust......
