The 41 Open and the 40 Express are completely different boats. Tiara used the Open for the fishing style open cockpit design while the Express was the cruiser style boat the has seating in the cockpit area which is also much higher off the water. Can get confusing when different manufacturers use the same wording for different style boats. I assumed that the OP has the cruising style boat which I would think would use the lift mufflers as the engines are much further towards the rear with no room for exhaust setup like the opens have.
