  • Covers an exhaust cut-out up to 8 inches in width
  • Prevents air from going above your diffuser and causing drag
  • Built from Aircraft-Grade Aluminum and Powdercoated Satin Black
  • Weighs .2LBS
  • A coverplate is essential if you have an 'over-diffuser' exhaust


The coverplate covers up your diffuser exhaust hole cutout (OEM or Difflow) and stops air from spilling above the diffuser. When air gets above the diffuser and gets trapped, it ends up causing drag and slowing you down like a parachute. This is a must for anyone with an exhaust that exits above the diffuser. Attaches bhy using existing bolts and 2 rivets/screws.
