Looks & Build Quality**
These slip-ons are a work of art—handmade in Italy from premium AISI 304 stainless steel, with anodized aluminum end caps that feel seriously robust. The finish options I considered—from sleek Black Chrome to glossy Chrome or matte Black Cerakote®—all radiate craftsmanship
Sound & Performance**
The growl is rich and confident—not too loud to intimidate but powerful enough to make its presence known on every open stretch. Choosing the Racing variant, I felt a genuine bump in response and acceleration—ZARD advertises +2.3 hp, and frankly, it lives up to that claim.
In contrast, the homologated (street-legal) version offers a more subdued tone and about +1.2 hp—ideal if noise regulations are a concern.
it & Installation**
Everything about the installation was tidy and straightforward. It’s a true bolt-on setup—no ECU tuning needed, so I had them on and road-ready in under an hour. Plus, designed specifically for Street Glide models from 2017 to 2024, the fit is flawless
Riding Experience**
This upgrade transformed my riding experience. The bike feels more alive—throttle response snaps, cruising is smoother, and the engine now sings in a deeper, more commanding tone. It’s the kind of change you feel immediately, both in your chest and under you.

I recently installed the ZARD Slip-Ons “4.5 Inches” Exhaust on my 2021 Harley-Davidson Street Glide, and I’m completely blown away by the transformation.

Craftsmanship & Finish
The build is exquisite—with stainless-steel bodies and anodized aluminum end caps that exude quality. I chose the Black Chrome finish, and it instantly elevated the bike’s aesthetic, giving it a bold, modern look without overpowering the classic lines of the Street Glide. The fit is meticulous—clear evidence of Italian attention to detail.
Sound Performance
At idle, the exhaust offers a deep, refined rumble—rich enough to draw attention, yet subtle enough to retain dignity. Rev the throttle and the tone deepens into a hearty growl that’s both satisfying and commanding. It has the perfect theatrical flair without crossing into excessive volume.

Power & Ride Feel
Opting for the Racing version, I felt a noticeable boost in performance—ZARD claims a +2.3 hp increase, and the bike feels more responsive at both low and mid-range RPMs. Acceleration is smoother, throttle response snappier, and overall, the ride feels livelier.
Installation
It was a breeze. The slip-ons bolt right on—no ECU remapping needed, just simple plug-and-play execution. Everything lined up perfectly, and I was back on the road in under an hour.

Riding a 2023 Harley-Davidson Street Glide, I wanted an upgrade that didn’t just sound better—but felt built with purpose. I went with the ZARD 4.5-inch Slip-Ons, and wow—Italian craftsmanship meets full-on touring muscle.

From the moment I unboxed them, I could tell these weren't your average bolt-ons. The handcrafted AISI 304 stainless steel finish, paired with those anodized aluminum end caps, look like they belong in a high-end custom build gallery—yet mount cleanly to your bike’s factory layout
Installation? A solid, no-nonsense hour with basic tools. Everything aligned perfectly—no ECU tuning required. I simply bolted them on, and they fit like they were always meant to be part of the bike
Now, the sound. At idle, it's a deep, commanding rumble—thick and rich, but not obnoxious. Open the throttle, and it’s a vibrant, throaty growl that turns heads. The racing version delivered a noticeable throttle kick and smoother pulls—ZARD quotes a +2.3 HP boost, while the homologated version delivers around +1.2 HP for street-legal compliance. That little bump in power made my Street Glide feel sharper and more alive—especially passing on the highway.

Visually, the finish I chose—Black Chrome—offers a bold, modern look without screaming for attention. You can also opt for plain Chrome or a tough Black Cerakote for over-1000 °C resistance if you want maximum durability and low-key style
Bottom line: the ZARD 4.5” Slip-Ons are more than just an exhaust—they’re a complete sensory upgrade. From the quality feel to the balanced sound and genuine performance bump, if you're riding a Street Glide (2017–2024) and want something that looks, sounds, and performs like art, you’re going to love these.
