How much louder are soft tops?

[lvs]

There are roof racks for the open top H1's.

I have an '01 open top and it is quiter than my friends '02 wagon. He drove mine for 3 hours on the interstate and couldn't believe how much quiter it was. The later year models do have better insulation and the tires have a lot to do with road noise as well though, so make sure you compare apples to apples. Also, some owners have put extra insullation in the dog house to successfully remove quite a bit of noise.
