The HKS LEGAMAX Sports Exhaust is a high-quality cat-back exhaust system engineered to enhance the driving performance, sound, and visual appeal of the Toyota GR Corolla (GZEA14H, G16E-GTS). Designed by HKS — a world-renowned Japanese performance parts manufacturer — this exhaust balances everyday drivability with a rich, engaging exhaust tone and improved flow characteristics.
Valve-less dual outlet design — Simplified layout with no active valve mechanism for consistent performance and reduced weight compared with complex valve systems.
Titanium slash-cut tailpipes (φ119 mm) — Large, stylish titanium tips provide a striking visual upgrade and a premium finish at the rear of the vehicle.
Stainless steel construction (SUS304) — Durable and corrosion-resistant materials ensure long-term reliability under various driving conditions.
HKS “EXHAUST ERROR CANCELLER” included — This module prevents engine management or OBD fault codes that can occur when removing OEM valve systems, for a worry-free installation.
The exhaust delivers a smooth and refined sound at low revs while offering a deeper, sportier tone as engine speed increases — all without excessive drone.
Enhanced flow characteristics help reduce backpressure relative to the stock valve-equipped system, which can contribute to improved throttle response and a more engaging drive.
