Rinehart Black 4 in. DBX40 Mufflers w/Black End Caps - 500-0183

Rinehart Racing, the world leader in V-twin exhaust, continues to innovate with the new DBX40 4” Slip on exhaust for 2017-Later HD Touring bikes. Featuring the same Performance Baffle as our DBX45, which have exploded in popularity, the new DBX40 gives your customers even more options for obtaining the Iconic Rinehart Racing sound they love on their new Milwaukee 8 bagger. This Classic 4” muffler, combined with the Performance Baffles, really allows the M8 motor to roar to life, unlocking the “old school” Harley sound that your customers have been desperately looking for, while providing the quality and performance Rinehart Racing is known for. You told us what you wanted and we’ve delivered.
