Best Istunt in 2026

After weeks of riding with this setup, the transformation in my Z125's character is undeniable. The ISTUNT full exhaust system replaces the heavy stock pipe with a lightweight stainless steel design that features a striking black and blue dual-layer finish. It is built specifically for the 2013-2018 Z125 and the 2019-2021 Z125 Pro, offering a noticeable boost in power performance. Because it lacks a removable baffle, expect a raw, aggressive sound that really lets the engine breathe. You get the essential mounting bolts, springs, and a spring hanger in the box, though you should be prepared to do a little bit of custom modification depending on your specific model year. It is a high-impact aesthetic and performance upgrade for a very reasonable price.

The aggressive roar of an aftermarket exhaust can quickly turn from thrilling to obnoxious when you're riding through quiet neighborhoods.

At just 82mm long, it fits snugly into a 51mm pipe, offering a direct way to reduce decibel levels. Installation is incredibly straightforward since it is designed to slide right into the exhaust joint, provided you have confirmed your pipe is exactly 2 inches in diameter.

The standout feature for me is the combination of a waterproof, non-slip bottom and those clever zipper lids that keep your gear from sliding around during sharp turns.

When you finally need that trunk space back, the entire unit collapses down to a mere 10cm, which is incredibly convenient for keeping a clutter-free vehicle.
