  • Harley Davidson Street Glide ST 2021-2023

The 4.33 inches racing slip-ons for the Harley-Davidson® Street Glide ST exhaust, combine the style and technology typical of Officine Italiane Zard products with the tradition and charm of the iconic Milwaukee Touring models. The exhaust system consists of a pair of fully hand-made racing silencers, made of AISI 304 stainless steel, in Italy.

To complete this refined system, there is a matte black Cerakote® finish and solid billet aluminium end caps with a laser-etched Zard logo on the upper part.

The improvements are not only stylistic: the Zard system for the Harley-Davidson® Road King Special exhaust range is 0,3 kg lighter than the original exhaust, but above all it offers an increase of 2,2 hp in maximum power. The Zard exhaust for the Harley-Davidson® Grand American Touring family is compatible with all models in the range powered by the 114 cubic inch engine available in Euro 5 homologated or racing version.

I recently installed the ZARD "4.33 Inches" Slip-Ons Exhaust on my 2022 Harley Davidson Street Glide ST, and I’m beyond impressed with the results. This exhaust has truly elevated my bike’s performance, sound, and overall ride quality.

First, the quality of the ZARD Slip-Ons is exceptional. The chrome finish is flawless, and the build feels robust and premium. The fitment was perfect, and the exhaust system installed without any issues. I had it up and running in less than an hour, and the instructions were clear and easy to follow, making the whole process smooth.

Performance-wise, the difference is noticeable from the first ride. The bike feels more responsive, with quicker throttle response and smoother acceleration. The exhaust really allows the engine to breathe more freely, making the bike feel much more powerful, especially at higher speeds. Whether I’m cruising on the highway or taking sharp turns, the bike feels more agile and powerful than before.

As for the sound, the ZARD "4.33 Inches" Slip-Ons provide an amazing tone. It has that deep, throaty Harley growl that makes you feel the power every time you twist the throttle. The sound is loud enough to command attention but not too overbearing for long-distance rides. It’s the perfect mix of power and refinement—just what I was looking for in an exhaust upgrade.

Another great benefit is the reduction in heat. The bike runs noticeably cooler now, which has made long rides in warm weather far more comfortable. No more worrying about exhaust heat burning my leg!

Overall, I’m extremely satisfied with the ZARD "4.33 Inches" Slip-Ons Exhaust for my Harley Davidson Street Glide ST. It’s a fantastic upgrade that adds performance, sound, and comfort to the ride. If you’re thinking about upgrading your exhaust, I highly recommend these slip-ons—they’re worth every penny!
