HKS Hi-Power Racing V1 Single Exit Catback Exhaust System - 2013-2016 Scion FR-S / Toyota 86 & GT86 / Subaru BRZ

The HKS Hi-Power Single Racing V1 Exhaust is a performance-focused single-exit catback designed for the FA20-powered FR-S, BRZ, and Toyota 86. Inspired by endurance and GT racing in Japan, the Hi-Power layout is built around one simple goal: creating a straighter, freer-flowing exhaust path with fewer unnecessary bends.

By using a large-diameter pipe, offset muffler layout, and lightweight single-exit design, this system helps improve exhaust flow, reduce weight, and deliver a more aggressive exhaust tone compared to the factory setup. It is a great choice for drivers who want a rawer, more motorsport-inspired sound and a cleaner performance look from the rear of the car.

Key Features

• Single-Exit Racing Layout: Straight-through inspired design reduces unnecessary bends for improved exhaust flow.
• Large 75mm Piping: Supports higher exhaust flow for naturally aspirated and forced induction setups.
• SUS304 Stainless Steel Muffler: High-quality stainless muffler and tip assembly for durability and appearance.
• SUH409 Stainless Steel Piping: Durable stainless piping commonly used in OEM-style exhaust applications.
• 97mm Titanium Tail: Large-diameter tip gives the rear of the car a proper HKS performance look.
• Weight Savings: Approximately 25.5 lbs compared to the stock exhaust at approximately 39.6 lbs.
• Improved Exhaust Tone: Produces a louder, more aggressive sound over stock.
• Inner Silencer Compatible: Compatible with HKS inner silencer 3306-RA072.

Why We Like It

This is the HKS exhaust for someone who wants a more aggressive, track-inspired single-exit setup. It drops weight, simplifies the exhaust path, and gives the FA20 a much more serious tone. If you prefer subtle and quiet, this probably is not the one. If you want classic HKS single-exit energy, this is exactly that.

Performance & Sound

The Hi-Power design improves exhaust flow by using a straighter layout and larger piping diameter. Turbocharged applications benefit from smoother exhaust flow and improved exhaust velocity, while naturally aspirated setups can benefit as engine tuning levels increase.
