Remus install

[bmwcliff]

I recently bought a Remus y-pipe for the Rockster, used, and wondered if there is anything special I should know in removing the factory cat box? Also, how does the o2 sensor get removed/installed? I just kind of figured it srewed out, then into the Y. Any insight, or wisdom is appreciated, thanks.:groovy

you'll need new gaskets to connect at the tail of the head pipes to the Remus Y-pipe. O2 sensor should unplug underneath the gas tank; follow it up from the pipe connection. use anti-seize on the O2 sensor threads, but keep it away from the sensor itself.
