Installed my new (used) 340i/440i muffler box and Performance diffuser -the exhaust shop has simply made an adapter sleeve to connect the 80mm muffler to 75mm exhaust hose. US F30 330i systems are 80mm on both ends but the Aussie ones are 75mm. But apart from that it was just plug n play. Sounds meaner and a lot louder now - love it :-)
