I just finished installing a HMF Swamp Series Exhaust, EHS Racing free-flow intake system with K&N filters, EHS air box cover, and EHS Bullet Box fuel programmer.
See my other vid to compair this soundclip to the stock OEM exhaust.

  • did you gain ur power box after u put all this on ur 550

  • @thelowlyfe17

    Not sure if I completely understand your question, but YES... I do notice a substantial increase in power and throttle responce with the addition of the EHS Racing components combined along with the HMF exhaust.

    It sounds like you are looking to recover lost low end drive ratio and torque after changing to larger/heavier wheels and tires, you may need to consider some modifications to your clutch system!
