yes you can
and im pretty sure it will improve performance by binning the cat

but you will need to put it back on for the mot as far as i know

may need remapping without the cat im not sure

someone will know more than me im sure

I removed an exhaust system from a "Cated" 318i and replaced with a non-cat system, she run much better and didn't do any remapping on it at all - and the lambda censer was disconnected and the loom for it tucked away nicely under the battery tray.
