2" AEM No-Weld O2 Sensor Mount - Our No-Weld O2 Sensor Mount enables users to mount an O2 sensor without having to weld a sensor bung onto the exhaust. Simply drill a hole in the exhaust, install the gasket, and bolt the clamp. It's that easy! The 3" mount will fit exhausts from 2.75" to 3" in diameter.
If you need to mount an O2 sensor and don't know how to weld or can't find someone who can, this is a permanent solution that replaces a weled in O2 bung. Now simply drilling a hole in the exhaust is all you need to do in order to add a wideband to your car!
