Have used one as a quick fit before having time to weld a bung on . It was on for 3 months and it started to leak and was also corroding around the hole drilled in the exhaust it fits over.


As a temporary fix to fit a wideband yes there ok as a long term solution I wouldn't recommend it . An exhaust shop will usually weld one on if you don't have a welder for about 30-50 bucks .
