The 4.33 inches racing slip-ons for the Harley-Davidson® Road King 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 just installed the ZARD "4.33 Inches" Slip-Ons Exhaust on my 2022 Harley Davidson Road Glide ST, and I am beyond impressed. This exhaust system has completely transformed the bike, enhancing both performance and sound in a way that I didn’t think was possible.
The build quality of the ZARD "4.33 Inches" Slip-Ons is outstanding. The chrome finish is sleek and high-quality, adding a sharp, custom look to my Road Glide ST. The materials feel incredibly sturdy and durable. The fitment was perfect, and the installation process was smooth. With the easy-to-follow instructions, I had them on in about 45 minutes.
Performance-wise, the difference was immediate. The throttle response is much smoother, and the bike feels more responsive overall. The bike has noticeably more power, especially in the low and mid-range, and I’ve noticed a smoother, more consistent acceleration. It just feels more connected to the road, and that has made my rides even more enjoyable.
As for the sound, the ZARD Slip-Ons have completely exceeded my expectations. They give my Road Glide ST a deep, throaty rumble that’s loud enough to be heard but not too overwhelming for long trips. The tone is rich and powerful, exactly what you’d expect from a Harley, and it really adds to the overall riding experience. I’ve already had several people compliment me on how good my bike sounds.
Another big improvement has been the reduction in heat. The bike runs noticeably cooler, which has been a huge relief during those long rides, especially on hot days. No more feeling that intense heat on my right leg!
