Maserati Gran Turismo 4.7 exhaust back box, part number 255951 which is RH side as far as I can see. The exhaust valve is stuck. It may be possible to free it or replace it. The actuator part moves freely but the part that rotates in the exhaust tube is stuck. Otherwise it's in very good condition. Big heavy item so collection preferred but will post although I will need time to package up the awkward shape. Please note again, the valve is not working.
