Hello. I’m new to Tiara ownership and this forum. Rookie question. While loving our new (old) boat, it’s loud as heck. I’m sure the 1985 exhaust ports above the waterline were cool in the Miami Vice era, they’re conspicuous these days. Can they be muffled when the risers are serviced, or does the cooling system preclude that? Obviously not a deal breaker, as we bought the boat. Thanks
