A lot of the time when you see no responses to a post it's because the original post wasn't worded correctly, and I think that may have been the case with mine. So, let me put it another way - when upshifting, it's as smooth as silk, you hear nothing but the change in engine note. When manually downshifting though, there's a noticeable noise as you do it a fraction of a second before you hear the engine, I mentioned above it's like a 'clunk' but it's almost more like a 'whoosh' (hard to explain). Just interested in whether this is normal for downshifts? Running with the factory-fitted race exhaust. Again, you don't hear this in Auto mode when it downshifts, only in manual.
