I recently installed the ZARD Stainless Steel Full Exhaust System on my 2021 Aprilia RS 660, and I couldn’t be more impressed. The difference it has made in both the sound and performance of my bike is incredible, and it has truly elevated the entire riding experience.

The installation process was smooth and straightforward. The exhaust system fit perfectly, and all components were included, making the process a breeze. The quality of the stainless steel is exceptional, and the finish looks absolutely stunning. The design complements the sleek, aggressive look of the RS 660 perfectly, adding a premium touch to the bike.

The sound is where this exhaust really shines. The ZARD system gives the bike a much deeper, more aggressive tone compared to the stock exhaust. It has a rich growl that makes the bike sound like a true performance machine, without being overwhelmingly loud. It’s just the right amount of growl — enough to turn heads and make a statement, but not so loud that it becomes annoying on long rides. I get so many compliments on the sound.

Performance-wise, I noticed a significant improvement right away. The bike feels much more responsive, especially in the mid-range, and the throttle response is sharper and more immediate. The exhaust frees up more power, making acceleration smoother and more exhilarating, especially when pushing through higher gears. It feels more agile and connected to the road, making every twist of the throttle more exciting.

Overall, I am extremely happy with the ZARD Stainless Steel Full Exhaust System. It has completely transformed my RS 660 — more power, a beautiful sound, and a high-quality build that will last for years.

I recently installed the ZARD Stainless Steel Full Exhaust System on my 2022 Aprilia Tuono 660, and I am absolutely blown away by the improvement in both performance and sound. This exhaust system is a true game-changer.

Installation was straightforward, with everything fitting perfectly right out of the box. The stainless steel construction is high-quality, giving the bike a sleek, aggressive look that matches its performance. It’s solid, lightweight, and incredibly well-made — you can tell this is a premium product just by handling it.

As for the sound, this exhaust system completely transforms the Tuono 660. The bike now has a deeper, throatier growl that perfectly complements its sporty nature. It’s much more aggressive than the stock exhaust but not obnoxiously loud. It provides a rich, satisfying tone that makes every ride feel more exciting, whether I’m cruising at low speeds or pushing the bike through twisty roads. I’ve had so many people compliment the sound — it really turns heads.

In terms of performance, the difference is immediately noticeable. The throttle response is sharper, and the bike feels more responsive across the entire RPM range. The power delivery is smoother, and I’ve noticed a significant boost in mid-range torque, which makes the bike feel even more exhilarating, especially when accelerating hard. It’s more fun to ride and feels much more connected to the road.

Overall, I’m thrilled with the ZARD Stainless Steel Full Exhaust System. It’s an outstanding upgrade for anyone looking to improve both the sound and performance of their Aprilia RS/Tuono 660.
