Bringing the Rinehart Rumble to Indian Touring Bikes

Rinehart Racing just dropped two models of slip-ons that finally give Indian riders the same legendary bark Harley owners have bragged about for years. Meet the DBX40 and DBX45 for Indian motorcycles. These are purpose-built to wake up Thunderstroke 111 / 116 and PowerPlus motors while keeping quality, fitment, and that unmistakable Rinehart tone front and center.

The DBX line borrows everything riders love about Rinehart’s Harley-specific cans—smooth flow, signature performance baffle, deep bass at idle, and a spine-tingling roar on the throttle—and repackages it for 2014-and-newer Indian baggers and touring machines. Whether you’re rolling a Roadmaster, Chieftain, Challenger, Pursuit, or Springfield, these slip-ons bolt up with zero drama and transform the bike from first start-up.

DBX40: Classic 4-Inch Muscle

The 4-inch DBX40 delivers a crisp, aggressive note that feels raw and “old-school Indian” without crossing into obnoxious territory. It’s ideal for riders who want more volume and growl yet still need clearance for Springfield’s rounded top bags. Chrome or black sleeves pair with matching or contrast-cut end caps, so dialing in the look is as easy as choosing your finish.

DBX45: Big-Bore 4.5-Inch Thunder

Step up to the DBX45 and the soundtrack drops half an octave. The larger canister adds visual heft under the bags and pumps out a bass-heavy rumble that stays mellow around town but comes alive when you twist the grip. Fitment is spot-on for baggers with flat-top lids; just note that Springfield owners will find reinstalling those curved lids a tight squeeze with this bigger body.

Common DNA

Both mufflers share the proven DBX performance baffle, flow bench-tuned to keep exhaust velocity high and back-pressure low, unlocking quicker revs and a noticeable seat-of-the-pants bump through the mid-range. They are 100 percent American-made, ship with Rinehart’s Forever Warranty, and meet the Qualified Manufacturer Declared 50-state emissions-compliant replacement part standard for 2014-later touring models.
