Rinehart 4 1/2″ DBX 45 Slip-On Mufflers For Harley Touring 1995-2016

Rinehart DBX 45: The Ultimate Voice for Your Twin Cam Bagger

The Rinehart 4 1/2″ DBX 45 Slip-On Mufflers represent the pinnacle of aggressive sound engineering for the 1995-2016 Harley-Davidson Touring generation. For decades, Rinehart Racing has been the gold standard for American V-Twin exhaust systems, and the DBX 45 is the result of years of refinement. While standard mufflers can often sound muffled or restricted on the Twin Cam 88, 96, and 103 engines, the DBX 45 utilizes a massive 4.5-inch diameter body. This increased surface area allows exhaust gases to expand more freely, creating a deep, resonant bass note that you can feel in your chest. Whether you are cruising through town or wide-open on the highway, these mufflers ensure your Road Glide or Street Glide has a presence that cannot be ignored.

The DBX Baffle: Science Behind the Sound

What truly separates the DBX 45 from other large-diameter slip-ons is the proprietary DBX performance baffle. Many “loud” pipes suffer from a loss of backpressure, which kills low-end torque and makes the bike sluggish off the line. Rinehart’s engineers solved this by designing a high-velocity baffle that maintains optimal exhaust gas scavenging while amplifying the engine’s natural low-frequency pulses. The result is a crisp, mechanical “bark” under heavy acceleration and a smooth, rhythmic rumble at idle. This acoustic tuning eliminates the “tinny” or “raspy” high-pitched sounds often associated with high-flow exhausts, leaving you with a clean, authoritative roar that is pure Harley-Davidson.

Expert Tuning & Installation Advice

As V-Twin performance experts, we’ve found that the DBX 45 is one of the most rewarding upgrades for a Stage 1 build. Pro Tip: Because these mufflers flow significantly more air than stock units, your Twin Cam engine will require more fuel to maintain a safe air-fuel ratio. We highly recommend using a fuel tuner like the Vance & Hines Fuelpak FP3 to recalibrate your ECM. This will prevent “decel-pop” and ensure your engine runs cooler, further deepening the exhaust note. Installation Note: When installing on 1995-2016 models, ensure your rubber muffler hangers are not cracked or dry-rotted; the 4.5″ body is heavier than stock and requires a secure mount. Always wipe the mufflers down with denatured alcohol before the first start-up to remove any fingerprints, as the oils can “bake” into the finish once the pipes reach operating temperature.

Legendary American Craftsmanship

Every set of Rinehart DBX 45 mufflers is 100% Made in the USA. The quality of the chrome and the precision of the CNC-machined end caps reflect Rinehart’s commitment to being the premier name in the industry. For the 1995-2016 Touring rider who wants the biggest look and the baddest sound on the market, the Rinehart 4.5″ DBX 45 is the definitive choice. It provides the perfect blend of high-end aesthetics, massive sound depth, and dyno-proven results.

Fitment Note: Fits all 1995-2016 Touring models. Not compatible with Trike models. Requires the use of factory-style muffler clamps (not included).
