HKS Legamax Premium Exhaust GR Yaris

HKS Legamax Premium Exhaust — Toyota GR Yaris Gen 1

After seeing over 40 GR Yaris exhaust options come through our doors, the HKS Legamax Premium is one we consistently recommend for owners who want a genuine step up in sound quality without the harshness or drone of cheaper systems. It's one of the most refined aftermarket exhausts available for the platform.

HKS is one of Japan's oldest and most respected performance tuning brands — and this exhaust has been developed specifically for the GR Yaris, not adapted from another platform. The result is a system that sounds purposeful and exciting without being antisocial on a long motorway run.

Key features

• HKS Legamax Premium stainless steel cat-back exhaust system
• Developed specifically for the Toyota GR Yaris Gen 1 (2020–2024)

• JASO certified — meets Japanese aftermarket certification standards

How does it sound?

We've fitted this system to our own GR Yaris demo car. At idle and low speeds it adds a noticeable rumble without being intrusive. On acceleration it opens up into a proper sports exhaust note — especially satisfying when pushing the 1.6T through the rev range. On a motorway cruise at legal speeds, it remains completely liveable.
