drummer?

[nukenwhite]

i ran across a bike parts wheeler dealer the other day, has a pipe that looks to be a drummer, anyone know the difference in diameter on a 12 vs. 9 at the exit tip, may need to modify. or order a new one. thanks

If I am not mistaken the header end pipe diameter is the same on both bikes as there are a lot of different pipes that are used on both bikes such as the jardine, the buell race pipe, and d&d

Info from http://www.americansportbike.com/ exhaust shootout test report.

The SS Drummer mufflers from KD Fab are custom built stainless steel shell with
aluminum end cap XB9 and XB12 mufflers. The XB12 and XB9 mufflers have different internal
volumes that are tuned to the pulse size of each engine.

Hope that helps.

there were no markings on it so it will just be a gamble i guess

Kevin's exhausts have Drummer engraved/stamped on the endcap on them as far as I know?

Call Kevin @ Kfab. He will answer all your questions and let you know what you can do from there. He is a very nice guy!
