Adding a Slip On system without recalibrating the EFI could lead to exhaust and or engine damage. Failure to add an EFI recalibration box will increase exhaust temperature beyond what the exhaust body, exhaust end caps, powder coating and internal packing material were designed. Always verify any EFI changes by doing a throttle chop/plug check in all the ranges of adjustment. Failure to do this will void your warranty.
