HKS 2022-2024 Toyota GR86 / 2022-2024 Subaru BRZ Hi-Power Spec L2 Cup Single Side Exhaust System - 32016-AT130

Part No.: 32016-AT130 | Available at Just Bolt-On Performance Parts

If you’re seeking to transform your GR86 or BRZ into a nimble, race-ready machine, look no further. The HKS Hi-Power Spec L2 Cup Single Side Exhaust System is meticulously engineered for maximum weight savings, improved torque, and stress-free engine rotation—ideal for both spirited street driving and track use.


1. Lightweight for Faster Handling

48% Weight Reduction

  • Stock Exhaust Weight: 16.2 kg
  • HKS Spec L2 Cup: 7.8 kg
    That’s nearly half the factory system’s weight, delivering quicker turn-in and sharper cornering response by reducing the yaw moment of inertia. HKS specifically placed the heavier sections closer to the middle of the car, diminishing the rear overhang weight and enhancing your vehicle’s overall balance.

Ultra-Thin Components

  • Silencer Pipe Thickness: 0.5–0.6 mm
  • Main Pipe Thickness: 0.8 mm (1.2 mm in high-stress areas)
  • Titanium Tail Tip: 0.8 mm inner, 1.0 mm outer
    Unlike traditional stainless steel exhausts with 1.2–1.5 mm thickness, HKS uses thinner materials to achieve an unmatched low weight—making it the lightest stainless exhaust with a mid pipe currently on the market (as of November 2023, per HKS). While durability has been thoroughly tested, be mindful of ground interference to prevent damage.

2. Meticulous Performance Gains

Optimized Pipe Diameter

The FA24 engine demands precise flow characteristics. Pipes that are too narrow or excessively large hurt exhaust efficiency and torque. HKS fine-tuned the 60 → 54 → 60 mm diameter transitions to achieve optimal exhaust velocity and minimal back pressure, boosting torque output throughout the mid-to-high RPM range (4,500–6,500 RPM).

Acceleration Tests: 3rd & 4th Gear

Using a chassis dynamometer, HKS measured the time it takes to accelerate from 3,500 to 7,000 RPM under varying loads (10 kW, 15 kW, 20 kW):

  • 3rd Gear (10 kW Load)

    • Stock: 4.60 sec
    • Spec L2 Cup: 4.50 sec
  • 3rd Gear (20 kW Load)

    • Stock: 7.58 sec
    • Spec L2 Cup: 7.20 sec

Similar improvements were recorded in 4th gear, with the Spec L2 Cup system demonstrating faster acceleration to target RPM under all load conditions.

Power & Torque Figures

  • Max Power: 159.9 kW @ 6,960 RPM (vs. 156.9 kW @ 6,980 RPM stock)
  • Max Torque: 236.7 Nm @ 3,230 RPM (vs. 234.7 Nm @ 3,240 RPM stock)

Peak power output rises while maintaining a robust midrange torque band, yielding smoother, more responsive performance right up to 7,000 RPM.


3. Innovations in Layout & Ground Clearance

Higher Ground Clearance

  • Clearance: 140 mm (7 mm more than stock) at the mid pipe
    The exhaust hugs the vehicle floor, running close to the rear subframe to preserve clearance. HKS added extra brackets to limit exhaust movement under spirited driving, reducing the risk of contact with suspension components or the road surface.

Reduced Rear Overhang Weight

The factory muffler tips the scales at a hefty 10.5 kg. HKS replaced it with a lightweight 2.7 kg section—nearly a 75% reduction in that rear-most portion. Shifting the mass toward the center of the car further enhances agility and roll response.


4. Technical Specs & Certification

  • Certification: JQR30233151 FA24
  • Main Material: SUS304 Stainless Steel
  • Pipe Diameter:
    • Main: 60 → 54 → 60 mm
  • Tail Tip Diameter: 94 mm (titanium construction)
  • Ground Clearance: 140 mm (mid pipe)
  • Drive-By Sound Level:
    • Stock: 82 dB
    • HKS Spec L2 Cup: 89 dB
  • Static Sound Level:
    • Stock: 57 dB
    • HKS Spec L2 Cup: 66 dB

While the system meets strict quality standards, keep in mind its lightweight design necessitates thin materials. Exercise caution on rough roads or large speed bumps to avoid potential damage.


5. Why Choose the HKS Hi-Power Spec L2 Cup for Your GR86/BRZ?

  1. Substantial Weight Savings: Dropping nearly half of the factory exhaust’s mass—ideal for enhanced cornering and track-readiness.
  2. Optimized for FA24: Perfectly balanced pipe diameters deliver strong midrange torque and increased peak output.
  3. Proven Acceleration Gains: Demonstrably better performance across multiple load conditions in both 3rd and 4th gear.
  4. Race-Oriented Design: Thinner gauge materials and strategic weight distribution reduce yaw inertia and improve high-speed stability.
  5. Improved Ground Clearance: Clever routing yields an additional 7 mm of clearance, reducing the risk of scraping.
