ever regret something almost immediately? trying to install the iss exhaust. quickly it's become a real pita. i have a 7/8"-22m o2 sensor socket and it just keeps slipping off and starting to round the edges.

anyone know what size it requires?
22mm will not work, as it is metric. 7/8" is the proper size. even when the exhaust is cold they should be really tight, mine were. so u have to put out but make sure u keep the socket on the sensor cuz if it is at an angle it will round the edges, there isnt much for the socket to grip on.
