The F6B I bought had Cobra pipes installed by the dealer. At idle they sounded fantastic. As soon as I was out on the road at 30 mph, I had to turn around and head back; the drone was that bad. In 15 minutes he had the Cobras off and the stock mufflers back on. After resuming the test ride I bought the F6B.
