I am just going to start this conversion. I have one question if I fit a defender 200 tdi exhaust manifold to a discovery 200 tdi will there be any problems. I am thinking this would be the best option so I can fit a defender 200 tdi exhaust or is there something I am missing. I found this online https://www.lrparts.net/exhaust-manifold-for-defender-200tdi-diesel.html . This seems better than the Steve parker modified exhaust or is there something I dont know and this wont work? Any advice grateful recieved
