Riding my 2020 Harley-Davidson Low Rider ST has always been a pleasure, but since installing the ZARD Slip-Ons “Alu” Exhaust, it's a whole new experience. Right from unboxing, the craftsmanship stood out—the AISI 304 stainless steel bodies, that sharp conical shape with visible MIG welds, and the sleek billet aluminum end caps simply elevate the look of my bike
Installation was shockingly smooth. I went with the Euro 4/5 homologated version in the matte black Cerakote finish—it lined up perfectly with the stock mounts, and I had everything bolted up in under an hour
Once on the road, the differences were clear. My ST shed about 4.3 kg in weight thanks to these slip-ons—a noticeable improvement in handling and nimbleness, especially when pinning it out of corners.
Performance-wise, I felt a solid bump—around +1 hp—which made acceleration feel sharper, especially in mid-range pulls. It’s subtle but exciting.
The sound—the real show-stopper—is pure ZARD. Deep, throaty, and commanding without crossing into obnoxious territory. It’s a perfect balance that turns heads without rattling your helmet.
All in all, the ZARD Slip-Ons “Alu” are a smart upgrade: they add polish, performance, and character. If you're looking to give your Low Rider ST a refined yet bold new edge, this is a no-brainer.

"I recently fitted the ZARD Slip-Ons “Alu” Exhaust on my 2019 Low Rider ST, and I couldn’t be more impressed. Right off the bat, the quality is immediately evident—AISI 304 stainless steel construction with that sleek, conical design and billet aluminum end caps give my bike a sharply modern, yet timeless look. Whether I chose the polished stainless or the matte black Cerakote finish, it turned heads at every stoplight."

"Installation was incredibly straightforward—everything lined up perfectly, and I had the setup completed in roughly an hour with just basic tools. The drop in weight is noticeable: around –4.5 kg on the Racing version and –4.3 kg on the Euro 4/5 homologated variant, really lightening the rear feel of the bike while tightening up handling and response."

"Out on the road, the Low Rider ST feels more planted and revs with a livelier, more spirited throttle. I estimate performance bumped up by around +1.5 hp on the Racing model (or +1 hp if you go with the homologated version)—enough to feel the difference in acceleration and mid-range punch, without upsetting the bike’s overall balance."

"But the best part? The signature ZARD sound. It delivers that classic Harley rumble—deep, rich, and commanding—without being obnoxiously loud. It’s the kind of tone that complements the character of the ST: refined, yet unapologetically bold."

"In sum, the ZARD Slip-Ons “Alu” are a fantastic upgrade: they’re lightweight, performance-boosting, eye-catching, and audibly satisfying. For anyone looking to elevate their Low Rider ST’s presence—both in sight and sound—this is a top-tier choice."

I recently installed the ZARD Slip-Ons "Alu" Exhaust on my 2022 Harley Davidson Low Rider ST, and I’m absolutely thrilled with the results. This upgrade has completely changed the riding experience, both in terms of sound and performance.

The build quality of the ZARD "Alu" Slip-Ons is outstanding. The aluminum finish is sleek and durable, perfectly matching the aggressive, yet stylish look of the Low Rider ST. The fitment was spot-on, and the installation was a breeze—took me less than an hour. The included instructions were clear, and everything lined up perfectly with the stock mounting points.

Performance-wise, the difference is immediately noticeable. The bike feels more responsive, with smoother throttle transitions and an overall increase in power. The acceleration is much more effortless, and the bike just feels livelier and more eager. Whether I’m navigating city streets or cruising on the highway, the bike handles much better and feels more planted.

Now, the sound is what really impressed me. The ZARD Slip-Ons "Alu" Exhaust provides a deep, throaty rumble that gives my Low Rider ST a perfect, classic Harley sound. It’s loud enough to be heard and grab attention, but it’s not overly aggressive. The tone is rich, resonant, and absolutely addictive to listen to. It’s the perfect combination of performance and style.

Additionally, I’ve noticed that the exhaust helps reduce heat from the engine. On warmer days, I don’t feel the same discomfort from the exhaust heat, which has made a huge difference in comfort during long rides.

All in all, the ZARD Slip-Ons "Alu" Exhaust has been an amazing upgrade for my Harley Davidson Low Rider ST. It has enhanced the bike’s performance, sound, and overall riding comfort. I highly recommend this exhaust for anyone looking to take their ride to the next level!
