    Think of the $$$$ H-D has spent on designing a new engine layout! :lolsign:

    I was thinking of the cylinder layout. V twin with one cylinder behind the other so the front cylinder runs cold and the rear one hot, then stick a single carb in the middle.
    :offtopic:

    Although H-D have made different cylinder layouts (single (both horizontal and verticle), flat twin (like BMW) and fore and aft twin (like a Douglas with gearbox above crank) and I think there may have even been a four cylinder (pre WW2) and even two strokes in the late 1940's, plus the Aeromachi's rebranded as H-D) they are most noted for the V twin. I often laugh at H-D (more so the people riding them) in a fun way, but I am thankful to them for selling their knowledge and patterns to the Japanese in the 1930's that has led to the wonderful bikes we have today from Japan.

    Sorry Damus, back to mufflers.

    If loud pipes save lives,
    imagine what learning to ride the thing will do.

    Its a myth, invented by noobs (and Americans) to justify horrible obnoxious systems on 250's.

    Personally I think almost all stock sports bike exhausts are not loud enough at all these days. And they look like ****, stupid shapes and plastic covers over them everywhere, which will fade and look worse in time. The lower displacement bikes especially.

    3 Reasons why you change an exhaust:

    Weight savings (+ performance)
    Looks
    Noise

    On the street there is no reason to change,, unless ground clearance issues.

    Huntsman, the ZXR750/ZX-7R was the best sounding bike at the Gunnedah drags by far! Not much of an exhaust on it :thumb_ups:

    Interesting driving around perth, traffic on the tonkin was going slow so the bikes started filtering. Shoulder check to change lanes started to move then suddenly a rider passes so I let him through. About to change again but hear the exhaust before seeing the bike, shoulder check there he goes.

    Guess which one I almost pulled in front of?

    And I'm very, very rider aware.
