  • Drop-in part. No modifications needed. Installed in space between x-over exit and shoulder of stock muffler inner layer.
  • Reduce x-over temp a small amount but consistent amount with about 15 F seen on average via laser surface reading at the x-over tube curve.
  • Unable to say at this point if more effective for cross bikes with or without cats. For no cats, though, it reduces the occasional decel backfiring some as it helps break up the left side decel reversion wave.

  • The Bad Ace Pressure Ring fits stock left side mufflers that have been recored/opened up for more flow, such as Gonzos, Adam Bombs, Drew Millers, Witchdoctors and several others.

    Does not fit aftermarket mufflers that do not use the stock muffler body, such as RCX 4.0, Lloydz, etc.

    Breaks up the pressure wave at the crossover exit as flow encounters the impedance of the slower flowing, higher pressures within the left muffler.

    Functions similar to how a drag pipe lollipop can break up the pressure wave at the exit as flow transitions to open air.

    Pressure Ring helps reduces x-over resonance and therefore sound volume by average or 1.5-2 dB @ 2750-3000 rpm with several baffle designs tested. Not a huge difference but may take the edge off or help with stereo sounds.
