I know the Dinan intake supposedly doesn't make any more power, but does it really sound that much different than stock? I'm surprised since the design is very similar to stock and the filter is completely within the housing - which I would think would make it difficult to hear?

What did they have to code differently?
Are these your stock 437M wheels painted or powder coated black?
