Troy Lee Designs/Red Bull/KTM

See the little extension off the back of the header on Shane McElrath's bike? The Troy Lee Designs/Red Bull/KTM bikes like a little more volume on the FMF Megabomb, and in the future they may change the shape of the cannister to accomplish the same thing. But for now, they've added the extension, and at A1 they had a microchip mounted on there, and were calling it an Active Noise Cancellation Circuit. We posted it up on our Instagram page for fun (and no one believes April Fool's Day pranks any more.)
