Swapping out the stock pipes on my 2020 Street Glide ST for the ZARD Full Kit 2:1 was one of the best mods I’ve ever done. Straight out of the box, you notice the craftsmanship—AISI 304 stainless steel headers, a sleek short-cone slip-on, and a sharply designed black-anodized aluminum end cap give the bike an unmistakable, refined, yet aggressive look. Available finishes in satin, matte-black Cerakote®, or polished make it easy to match your bike’s style
I went for the Racing version, and the performance gains were no joke: the system drops your bike’s weight from stock by 9.5 kg, down to just 5.6 kg total, and delivers a solid +4 hp boost—sheer joy on acceleration My riding buddy, who chose the Euro 4/5 homologated option for weekend legality, still enjoyed nearly the same benefit: –9.3 kg and a respectable +2.1 hp gain
Installation was fairly straightforward—fits cleanly and aligns perfectly with the rear frame. On the road, the ZARD gives you a deep, plush rumble that’s got bite when you twist the throttle, but never crosses into obnoxious—perfect for both cruise nights around Quito and spirited canyon runs.

Beyond power and sound, it feels like swapping in instant performance and style. If you're looking to elevate your Street Glide ST into something sharper, lighter, and louder—in all the best ways—the ZARD Full Kit 2:1 is an exceptional upgrade.

Once installed, the performance gains were immediately noticeable. Opting for the racing version, I shed a remarkable 9.5 kg compared to the stock system, and the power increase—about 4 hp—made the throttle response crisp and thrilling For riders focused on compliance, the Euro 4/5 homologated version still drops 9.3 kg and adds 2.1 hp—not quite as wild, but still a worthy upgrade
Beyond numbers, the sound profile is beautifully balanced: a deep, rich note that’s sporty without being intrusive—ideal for both spirited rides through winding Andes roads and relaxed cruising around Quito. I also appreciated the multiple finish options—satin, matte-black Cerakote®, or polished—that let me personalize the look to match my bike’s style

The headers, sleek short-cone slip-on, and black anodized aluminum (or Cerakote® finish) end cap give the bike a stealthy, sculpted aesthetic that’s impossible to miss
Weighing in at just 5.6 kg in the racing variant—or 5.8 kg for the Euro 4/5 homologated version—the weight savings are jaw-dropping compared to stock: up to –9.5 kg lighter The performance bump was equally noticeable: I gained around 4 hp on the racing model, which transformed mid-range acceleration into something truly exhilarating
Installation was straightforward, and once on, the exhaust delivers a deep, rich tone that’s sporty without being rowdy—perfect for both winding roads and urban cruising. The Cerakote matte-black finish hasn’t flaked or discolored despite my frequent rides through Quito’s varied conditions.
