Yamaha R3 OEM exhaust weight, headers, muffler, slip-on, heat shield

I thought I would just put this info up as a separate post so it can be referenced easily to compare the aftermarket exhaust weights.  The OEM headers, catalytic converter, and muffler weigh 11 lbs 9.2 oz.  The OEM slip-on weighs 6 lbs 4.8 oz, and the OEM heat shield weighs another 5.5 oz.
