Jardine RT1 Quiet Exhaust Module insert for 2-1/4" TIP Jardine 8-QMI1
The QMI is a sound attenuation device that installs easily in under a minute. You can now have the best of both worlds. Maximum power from a race core or the neighborhood friendly tones of the QMI unit. Specifically designed for race core equipped modles. The QMI allows you the option of substanially decreasing the sound level of your racing system when you need to. Constructed from aluminum billet and CNC'd to exacting tolerances, the module features a "red" high temperature silicone O-ring to assure proper sealing. Decreases sound levels an average of 6-8 decibels on race core equiped modles. That correlates to an average sound level of 92-95 dbA with the QMI installed. May require jetting change.
