Spy Photos: New Yamaha Exhaust 22

The Toyota/JGRMX/Yamaha crew are doing some testing to get prepped for the Monster Energy Cup, and we spied something interesting on one of their bikes. It's apparently a new design from Yamaha (and built by FMF) that wraps nearly around the cylinder. This design allows them to remove the tornado section under the  seat like on the stock bikes, and also move the muffler forward quite a bit. A shield at the front keeps the pipe and radiator hoses separated.

The pipe header is tucked tightly around both sides of the cylinder.

Here's how far the muffler sticks out on the new style.

Justin Brayton riding with the more traditional version. See how much longer the muffler is?
