Nameless Performance Muffled Single Exit 2.5in Track Pipe 2013-2016 BRZ / 2013-2016 FRS

This is their track pipe for the new BRZ/FR-S. The intent behind this is to provide the lightest option available for an axleback, while still keeping the volume a bit more civil than the delete. 

This race pipe weighs in at a mere 6 pounds. Compare that to the stock brick of a muffler that weighs 26 pounds and you save 20 pounds.
