Rinehart DBX 45: Unleash the Sound of Your Milwaukee-Eight

The Rinehart 4 1/2″ DBX 45 Slip-On Mufflers for 2017-2024 Harley-Davidson Touring models represent the perfect marriage of acoustic science and V-Twin performance. When Harley-Davidson introduced the Milwaukee-Eight engine, it brought unprecedented refinement, but it also silenced the iconic soul of the exhaust. Rinehart Racing, a leader in the performance bagger movement, developed the DBX 45 specifically to solve this. By utilizing a massive 4.5-inch diameter body, these mufflers create a massive resonance chamber that naturally lowers the frequency of the exhaust note. Whether you are riding a Road Glide, Street Glide, or Road King, the DBX 45 provides a deep, percussive “thump” that you can feel, ensuring your bike finally sounds as powerful as it looks.

The DBX Baffle: Aggressive Sound Without Power Loss

The core of this system is the proprietary DBX performance baffle. Many “loud” mufflers on the market rely on wide-open pipes that destroy backpressure, causing a significant loss in low-end torque—the very thing the M8 engine is famous for. Rinehart’s engineers spent years on the dyno perfecting a high-velocity baffle that allows for maximum sound amplification while maintaining the scavenging effect required for peak engine performance. The result is a crisp, mechanical bark under load and a smooth, rhythmic low-frequency rumble at idle. This engineering ensures that while you get an aggressive sound, your bike still pulls hard through every gear, making it the ideal choice for both city cruising and long-haul touring.

Expert Tuning & Installation Advice

As experts in M8 performance, we have seen the DBX 45 become the top-selling slip-on for a reason. Pro Tip: Because the DBX baffle significantly increases exhaust flow compared to the restrictive factory cans, your engine will naturally run leaner. To get the best results and ensure engine longevity, we highly recommend a fuel tuner like the Vance & Hines Fuelpak FP4. This will help you calibrate the air-fuel mixture to match the new airflow, resulting in a cooler-running engine and a deeper, more stable exhaust note. Installation Note: When mounting on 2017-2024 models, remember that the inlets are different sizes (left and right). Always use new muffler clamps to ensure a gas-tight seal. To maintain the premium finish, wipe the pipes down with denatured alcohol before the first heat cycle to remove skin oils that could otherwise be permanently “baked” into the chrome or black ceramic.

American-Made Racing Pedigree

Every Rinehart DBX 45 muffler is 100% Made in the USA. From the precision TIG welding to the depth of the plating, Rinehart’s commitment to quality is evident. These mufflers are designed to resist the intense heat of the Milwaukee-Eight engine without yellowing or blueing. For the 2017-2024 Touring rider who wants the ultimate “Performance Bagger” sound and look, the Rinehart 4.5″ DBX 45 is the definitive choice. It delivers a soundtrack that is as legendary as the Rinehart name itself.

Fitment Note: Fits all 2017-2024 Touring models. Not compatible with Trike models. Re-uses factory head pipe heat shields for a seamless, factory-integrated look.
