I recently upgraded my 2021 Harley-Davidson CVO Road Glide with the ZARD Slip-Ons 4.5-Inch, and let me tell you—this is no ordinary upgrade. Here’s why I couldn’t be more thrilled:

Italian Craftsmanship Meets Rugged Touring

From the second I held these silencers, the difference was obvious. Handcrafted in Italy using AISI 304 stainless steel with billet anodized aluminum end caps and a sleek ZARD nameplate—the quality is palpable. The finish options—Chrome, Black Chrome, or Black Cerakote—add a refined, custom look that elevates the bike’s presence
Performance That You Can Feel

I chose the Racing version, and the results were immediate: throttle response sharpened noticeably, and every twist of the wrist feels more alive. That’s backed by a claimed +2.3 hp gain over stock—far more than just marketing flair
Tone That Demands Attention (Without Overdoing It)

At idle, the exhaust delivers a rich, commanding rumble—those around you will know you’ve arrived, without ear-piercing volume. Crack the throttle, and it blooms into a smooth, throaty growl that’s powerful yet refined. It strikes the perfect balance—audible, assertive, but never overpowering
Hassle-Free Installation

On the installation front, ZARD hit the mark. Fitment was spot-on—bolted right on my bike with no tweaks needed. I had everything wrapped up in under an hour, and best of all, there was absolutely no need for ECU remapping—I was road-ready almost immediately
The Final Verdict

If you’re looking for an exhaust solution that delivers in appearance, sound, performance, and ease of installation, these ZARD Slip-Ons are a standout. My CVO Road Glide now not only looks sharper and sounds more authoritative—it rides with newfound confidence. This upgrade doesn’t just add value—it transforms the experience.

As a long-time Harley afficionado, I’ve swapped out my share of exhausts—but the ZARD 4.5-inch Slip-Ons for the CVO Road Glide (2017–2024) truly stand apart. Here's why:

Craftsmanship That Speaks

Right out of the box, you can feel the Italian quality. These silencers are hand-made in Italy from AISI 304 stainless steel, topped with billet anodized aluminum end-caps and the iconic ZARD nameplate. Whether you go for Black Chrome, Chrome, or Black Cerakote, each finish exudes premium flair
A Sound That Commands Attention

Idle or cruising, these slip-ons deliver a deep, commanding rumble—a sophisticated growl that strikes the perfect balance between bold and refined. And when you open the throttle? The response is immediate, smooth, and exceptionally engaging.

Performance You Can Feel

Choosing the racing version, I instantly noticed crisper throttle response and livelier acceleration. ZARD advertises a +2.3 hp gain for racing models (and +1.2 hp for homologated versions), which aligns perfectly with what I experienced on the road. Every ride now feels more connected and potent.

Easy Installation, No Fuss

Getting these installed was refreshingly painless—no ECU remap required. I had them bolted on and ready to ride in under an hour. The instructions were clear, and everything aligned beautifully
Final Thoughts

If you’re after an upgrade that marries form and function—think standout style, seamless installation, satisfying acoustics, and tangible performance gains—the ZARD 4.5-inch Slip-Ons are a stellar choice. My CVO Road Glide not only looks sleeker but also feels and sounds more alive than ever.

I recently swapped out the stock mufflers on my Harley-Davidson CVO Road Glide with the ZARD 4.5-inch Slip-Ons, and wow—what an upgrade.

From the moment I handled the silencers, I could feel the premium quality: handcrafted in Italy from AISI 304 stainless steel, topped with billet anodized aluminum end-caps and a sleek ZARD nameplate. I opted for the racing version, and I can genuinely sense the added 2.3 hp—my bike’s throttle response feels noticeably sharper and more alive
Installation was a breeze—smooth and hassle-free. Right out of the box, no ECU remap required; had the old cans off and new ones snugged in under an hour
Now, let’s talk sound. At idle, the bike’s got a deep, commanding rumble that turns heads without overpowering the senses. Hit the throttle, and it lets out a refined growl—powerful yet melodic, bold but not obnoxious. Every ride feels like a performance.

The final touch? The craftsmanship and finish are second to none. The Black Cerakote, Chrome, or Black Chrome options aren’t just stylish—they elevate the bike’s entire aesthetic profile

I recently installed the ZARD Exhaust Slip-Ons (4.5 inches) on my Harley-Davidson CVO Road Glide (2019 model), and the difference is nothing short of spectacular.

From the moment I unboxed them, the craftsmanship stood out—the hand-made silencers are elegantly finished in Black Cerakote with billet anodized aluminum end caps and a discreet Zard nameplate, giving my ride a sophisticated, custom look
Installation was surprisingly straightforward—I swapped out the old cans and had these seated and tightened within about half an hour. Plus, no ECU remapping was needed, so I was back on the road in no time
The sound is deep, refined, and satisfying—just the right balance of growl and polish. Performance-wise, I installed the racing version, and you can feel the difference: throttle response is sharper, and there’s a noticeable pop of power—ZARD claims a bump of +2.3 hp over stock, which absolutely aligns with how it rides now. I’ve also noticed a slight weight saving compared to the stock cans, lending the bike a more agile feel when cornering.

If you're looking to elevate your bike’s aesthetics, gain a bit more performance, and enjoy a throatier exhaust note without fussing with ECU tuning—I can’t recommend these enough. Worth every penny!
