Details

    By building off the great foundation of the standard Power Core II, the Shorty Power Core II provides the same quality, performance, and looks in a shorter overall package.

    The Shorty still has similar power generation in the low and mid rpm, but with a smaller form factor you get better mass centralization. That means the silencer is kept closer in towards the bike, shifting more weight towards to center of gravity to promote handling.

    A smaller package also means there’s less to get crunched if your bike goes down. But, it's made from durable extruded aluminum alloy with a stinger of stainless steel, the shorty can take a hit and keep going strong.

    Specs:
  • Based on standard Power Core II
  • Shorter silencer body centralizes mass
  • Increases response and power in low and mid ranges
  • Extruded aluminum body with oval canister shape
  • Great for aggressive supercross riding
  • Easy breakdown and maintenance
  • Stainless end cap and stinger
  • Made 100% in the USA

Combined this with a Fatty and 14/49 '17 150SX and it made amazing changes to the bikes performance. Can't beat screaming by a 4 stroke.

Can I combine the FMF Power Core II Shorty Silencer with the SST Pipe? What could I expect?
A shopper on Aug 28, 2016
BEST ANSWER: FMF only specifies that you cannot use the SST silencer without the SST pipe, but make no claim that you cannot use the SST pipe with any other FMF silencer, therefore, I believe you can use the Power Core II with the SST pipe.
