Have just put mine through MSVA for entry into the UK but I refitted the AIS, original exhausts, etc., as a precautionary measure as nearest station is 30 miles away. There is a guy with a suzuki intruder at work and he passes the MOT with some sort of open custom pipe but have not tried it myself here for many years. If station is near and if there is not a retest fee, I am not sure if there is, why not give it a go. When refitting the AIS the clips that hold the flexi pipes onto the chrome pipes from the cylinder head are very difficult to reuse so replaced with jubilee clips.
