This neoprene nozzle has a special coupling system designed for exhausts integrated into the vehicle's bumper. Complete with 2 metal rods that plug into the exhaust pipe with a button on the side, ensuring a perfect fit and preventing damage to the chrome of the exhaust. Clamps or conventional exhaust extraction nozzles are not suitable in these cases, as the smoke extraction would not be efficient due to the exhaust pipe not protruding.
