I recently upgraded my 2022 Harley-Davidson Road Glide with the ZARD Slip-Ons “4.5 Inches” Exhaust, and I’m absolutely blown away. Right out of the box, the craftsmanship had me impressed—these slip-ons are entirely handmade in Italy from AISI 304 stainless steel, with billet anodized aluminum end caps that feel premium to the touch
The range of finishes—Chrome, Black Chrome, and Black Cerakote—let me match my exhaust’s look to my bike’s aesthetic perfectly
Installation was a breeze—this bolt-on kit required no ECU remapping or complicated tools, and it fit flawlessly on my bike Within an hour, I was ready for my first ride with the new pipes.

Sound-wise, these slip-ons deliver. At idle, there's a deep, authoritative rumble that commands attention without being obnoxious. When I twist the throttle, it bursts into a robust, resonant growl that turns heads without overwhelming the streets. The tone feels rich and refined—just what you'd expect from a high-end upgrade.

Performance improvements are more than audible—they’re noticeable. I went with the Racing version, and the increased responsiveness is unmistakable—the acceleration feels sharper and livelier. The brand claims a +2.3 hp gain for the racing spec, compared to +1.2 hp for the homologated version This added power really livens up mid-range pulls and makes daily cruising smoother.

Despite the lighter weight, the build feels solid—ZARD lists the Racing slip-ons at 9.5 kg and the Homologated at 9.8 kg You get that high-quality Italian build without unnecessary bulk.

In short, if you want to elevate your Road Glide’s aesthetics, sound, and ride quality, the ZARD 4.5″ Slip-Ons are a top-tier choice. Stunning design, richer sound, smoother performance—all wrapped in authentic craftsmanship. Definitely worth the upgrade.

From the moment I mounted the ZARD Slip-Ons "4.5 Inches" Exhaust on my 2019 Harley-Davidson Road Glide, I sensed it was a game-changer. First off, the build quality is top-tier—crafted in Italy from stainless steel, with precision-welded seams and billet anodized aluminum end caps that give the bike a sleek, refined edge
I opted for the racing version, and the difference is both audible and tangible. At idle, the pipe emits a deep, commanding rumble—bold yet not overwhelming. When you open the throttle, the growl blooms into a restrained but enthusiastic roar that turns heads without overpowering the road. It's that perfect harmony of aggressive and elegant.

Performance gains are seriously noticeable. ZARD touts a +2.3 hp boost for the racing version, and I can feel it: throttle response is sharper, acceleration is smoother, and the bike feels livelier across the rev range Even cruising feels more effortless and dynamic.

Installation was a breeze thanks to the bolt-on design—no need for ECU tweaks or complex calibration. Everything fit snugly, and I was back on the road within an hour
I also appreciate the variety of finishes available—Chrome, Black Chrome, and Black Cerakote—so you can match your bike’s aesthetic preferences
In summary: the ZARD Slip-Ons “4.5 Inches” look elite, sound commanding, and deliver noticeable performance gains—all wrapped up in authentic Italian craftsmanship. If you're looking to elevate both the sound and feel of your Road Glide, this upgrade is one of the best investments you can make.

I recently fitted the ZARD Slip-Ons “4.5 Inches” Exhaust to my 2021 Harley-Davidson Road Glide, and the transformation is nothing short of phenomenal. From the first glance, the craftsmanship is immediately evident—the stainless steel body, meticulously handcrafted in Italy, exudes premium quality, and the billet anodized aluminum end-caps deliver that elegant finishing touch
In chrome finish, the pipes gleam intensely, giving my bike an aggressive, high-end aesthetic that stands out beautifully against the traditional touring silhouette. The installation was smooth—everything aligned flawlessly, and I had it bolted on in under an hour without any fitment fuss.

But the real difference is in the sound and performance. The idle is now a deep rumble—rich and commanding; once I crack open the throttle, the roar is assertive but refined—not excessive, just powerful. It’s the kind of tone that commands attention and enhances the ride without overwhelming it.

Performance gains are noticeable. Opting for the racing version, I felt a crisp +2.3 hp boost—enough to sharpen throttle response and make acceleration noticeably smoother. Even in everyday cruising, the engine feels more alive and efficient
Riding through winding roads or open stretches, the enhanced power delivery combined with that gritty yet polished exhaust note makes every mile more thrilling. Plus, I appreciate that there’s a homologated option (with a slightly reduced gain of +1.2 hp) for those who need to stay strictly road-legal
In short, if you're looking for a high-quality, performance-driven upgrade that elevates both the look and feel of your Road Glide, the ZARD Slip-Ons “4.5 Inches” are an exceptional choice—Italian craftsmanship meets undeniable street presence.

I recently upgraded my 2023 Harley Davidson CVO Road Glide with the ZARD Slip-Ons "4.5 Inches" Exhaust, and it’s been an absolute game-changer. From the installation to the first ride, I was blown away by the difference in performance and sound.

The craftsmanship of the ZARD slip-ons is top-notch. The chrome finish is flawless, and the pipes feel incredibly durable. The 4.5-inch diameter adds just the right amount of boldness to my CVO Road Glide, making it look even more custom and aggressive while maintaining a clean, classy appearance. The fitment was perfect, and everything lined up smoothly, making installation a breeze.

The sound is where these slip-ons really shine. At idle, the bike has a deep, powerful rumble that immediately catches attention. When you twist the throttle, the exhaust roars to life with a smooth, throaty growl that feels like it belongs on a performance bike. It’s loud enough to be heard but not so loud that it becomes intrusive. The tone is rich and refined, with just the right amount of growl to make every ride more exciting.

Performance-wise, I noticed a significant improvement. The throttle response is much sharper, and the bike feels smoother and more responsive, especially when accelerating or cruising at higher speeds. The engine seems to breathe better, which results in smoother power delivery and improved overall performance. Whether I’m hitting the open road or taking on tight curves, the bike feels more stable, and I feel more in control.

Installation took about an hour, and the process was as easy as it gets. The instructions were clear, and the quality hardware provided by ZARD made the entire process painless.

If you're looking for an upgrade that improves the sound, performance, and aesthetics of your Harley Davidson CVO Road Glide, I highly recommend the ZARD Slip-Ons "4.5 Inches" Exhaust. It’s a premium product that will elevate your riding experience, and I couldn’t be happier with the results.
