New to Morgan, but as a Lotus driver for many years, creaking, wind noise, and exhaust drone are very common problems in Elise models, and most everything is plastic or metal, so a lot of friction points with nothing soft in between. Many Lotus drivers have used sound deadening materials to good effect, including products like Dynamat applied against the aluminium floor pans (so between floor and carpet), inside the glass fiber doors, behind the dash panels, and against the back firewall (engine is right behind one's head). On the Lotus, application of neoprene tapes, adjusting the angle and tilt of the windows to better fit the top, etc. help with wind noise. Exhaust thrumming and drone can be muted a bit, but the only real solution is a change of the exhaust system.
