HKS Hi-Power Muffler SPEC-L2 ZD8 FA24 - 2022+ Toyota GR86 / Subaru BRZ

Looking to add a refined, sporty exhaust note to your GR86 or BRZ without going over the top? The HKS Hi-Power Muffler SPEC-L2 is a high-quality cat-back exhaust designed to improve sound, reduce weight, and enhance driving feel on the 2022–2026 Toyota GR86 and Subaru BRZ.

HKS is well known for building exhaust systems that balance performance, fitment, and sound quality. The SPEC-L2 continues that reputation with ultra-thin stainless steel construction, a carefully tuned muffler design, and a silent chamber that helps reduce unwanted drone while still delivering the signature HKS tone.

Key Features

• Lightweight Stainless Construction: Ultra-thin stainless steel piping and silencers help achieve weight levels competitive with titanium exhaust systems.
• Sporty HKS Sound: Tuned for a deeper bass tone with a clean, refined exhaust note.
• Reduced Drone: Integrated silent chamber helps eliminate annoying cabin drone.
• Equal-Length Layout: Unique exhaust shape with equal length on each side helps produce a clear, balanced exhaust sound.
• FA24-Specific Pipe Sizing: Pipe diameter selected to match the higher-output 2.4L engine for strong exhaust performance.
• Improved Driving Performance: Reduced weight and lower exhaust pressure help improve overall response and feel.
• Optional Tip Customization: Compatible with optional tail tip covers in titanium, carbon, and blue stainless steel finishes.
• Japanese Regulation-Friendly Version: 32016-AF101 is designed to meet Japanese regulations and is quieter than 32016-BT004.

Why We Like It

The SPEC-L2 is a great choice for owners who want a quality exhaust that feels mature but still adds excitement. It gives the GR86/BRZ a sportier sound, drops weight over the factory system, and avoids the excessive drone that can make some aftermarket exhausts tiring on longer drives.
