Description
The HKS Hi-Power Spec L2 Cup Exhaust is the ultimate lightweight exhaust system designed to enhance the performance and handling of the 2022+ Toyota GR86 and Subaru BRZ. Engineered for enthusiasts who demand precision, this system improves torque, acceleration, and cornering dynamics while significantly reducing weight.
Key Features
-
Lightweight for Enhanced Handling
- Weighs only 7.8 kg, reducing nearly 48% of the stock exhaust’s weight (16.2 kg).
- Weight distribution shifted toward the vehicle's center reduces the yaw moment of inertia, improving cornering stability.
-
Optimized Pipe Design
- The pipe diameter (D60mm⇒D54mm⇒D60mm) is meticulously calculated for the FA24 engine, balancing exhaust efficiency and backpressure to deliver optimal torque and smooth flow.
-
Performance Improvements
- Acceleration: Enhanced acceleration across various loads in both 3rd and 4th gear.
- Power & Torque:
- Peak Power: 159.9 kW @ 6960 RPM (Stock: 156.9 kW).
- Peak Torque: 236.7 Nm @ 3230 RPM (Stock: 234.7 Nm).
-
Innovative Materials
- Constructed from SUS304 stainless steel, featuring thin, durable pipes and silencers (Main Silencer: 0.5mm; Mid Silencer: 0.6mm).
- Titanium material for the tail tip enhances strength and reduces weight.
-
Superior Layout for Racing
- Minimum ground clearance of 140 mm (7mm higher than stock).
- Pipes positioned closer to the subframe for improved aerodynamics and reduced road interference.
