    Um exhaust but the shelf in the garage is more suited. Good luck and hope you enjoy the headaches it will bring.

    Only problem I had with it in the drop pipe was the ski had to be ran over 2k rpms to keep the sensor dry,which isn't very rec friendly. I'd love to hear some feedback from someone who used the o2 plate that sandwiched between the two exhaust pipes

    WHY, are you worried about emissions control (LOL)

    O2 sensor cant read in liquid.+ engine would be Intentionally
    tuned to run a bit rich (helps not to melt pistons).

    Weather conditions change, 100% tune is better than ok.
    They work well on motor bikes

    A dynojet tunes on the fly for the conditions. The engine builder said it may help to optimize fueling
