HKS Hi-Power SPEC-L II Exhaust

HKS Hi-Power SPEC-L II Exhaust - Toyota GR86 / Subaru BRZ (2022+)

Ultra-Lightweight Performance & Sophisticated JDM Acoustics

Experience the perfect blend of weight reduction and acoustic refinement with the HKS Hi-Power SPEC-L II. Engineered specifically for the high-revving 2.4L FA24 engine, this "Lightweight Sports" exhaust system focuses on improving vehicle agility by shedding significant weight behind the rear axle. By using specialized thin-walled SUS304 stainless steel, HKS has created a system that provides the durability of steel with the weight-saving benefits usually reserved for titanium. Finished with iconic carbon-wrapped tips, the SPEC-L II offers a premium look and a deep, resonance-free sound that perfectly complements the character of the GR86 and BRZ.

What’s Included in the Box:

- HKS Hi-Power SPEC-L II Cat-Back System: Mid-pipe and dual rear-exit silencer assembly.

- Carbon Fiber Wrapped Tips: (2) 94mm lightweight carbon-trimmed exhaust tips.

- Installation Kit: Premium gaskets, specialized bolts, and high-durability hangers.

The HKS Performance Advantage

- Massive Weight Reduction: Weighing in at only 11.4kg (approx. 25.1 lbs), this system is roughly 30 percent lighter than the bulky 16.2kg (35.7 lbs) factory unit. This improves the car's center of gravity and helps the rear end rotate more freely in corners.

- Engineered for the FA24: Unlike universal mufflers, the SPEC-L II features 65mm piping that splits into dual 50.8mm paths, specifically tuned to maximize the torque curve and throttle response of the 2.4L boxer engine.

- Refined JDM Sound: HKS utilizes high-quality "Advantex" glass wool packing and internal baffles to ensure a sporty, bass-heavy note under load, while maintaining a drone-free experience during highway cruising.

- Titanium-Inspired Wall Thickness: By using 0.5mm to 0.8mm thin-wall stainless steel, HKS achieves extreme weight efficiency without the "pingy" resonance sometimes found in full-titanium pipes.

- Carbon Fiber Aesthetic: The 94mm tips are wrapped in genuine carbon fiber, providing a technical, high-end finish that perfectly fills out the factory rear bumper cutouts.

Precision Tip: This exhaust is the SPEC-L II, which is the updated version of the original SPEC-L. It is designed to be a direct bolt-on. To keep the carbon fiber tips looking their best, we recommend applying a high-temp ceramic coating to the tips before installation. This makes it much easier to wipe away exhaust soot and prevents the clear coat on the carbon from yellowing over time.
