FMF PowerCore 4 Slip-On Exhaust - Aluminum

First off the directions were insufficient for dealing with the EXUP system cables. Next step install pipe, the connection was so loose I had to purchase a $20 tube of silicone to seal the two pipes together. I fell the install kit could’ve come with a small tube as it is recommended in the instructions. Lastly, the hardware needed to secure the muffler to the bike was not included. The hardware from the OE pipe was too short or the wrong diameter resulting in another $20 trip to the parts store. Was strongly considering getting the FMF header pipe but will now be looking elsewhere for upgraded components.
