That is worth its weight in gold,the arc just right and fits like a glove, great quality and happy with it.
Threads were good, and welded was bound to be perfect,welder by trade and had no issue after cleaning the protective oils off rigging them to the exhaust I built for my truck.
Just drill a hole and weld these on. Be sure to use a little anti-sieze on the plugs if you use those.

Material is pretty solid and thick, But is NOT designed to fit 3in piping. Had to do a lot of grinding and even than a lot of gap filling with my welder, get the right diameter for the pipe your welding on and this is a solid product

Needed to attach our O2 sensor to the dirt bike exhaust pipes for testing on our dyno. We welded these into our test pipes and when you want to actually test ride our tunes on the track we just screw in the plug.They were delivered quick at a fair price!
