2013-2024 Subaru BRZ Catback Exhaust w/ Dual/Single Burnt/Polished Tip

Subaru BRZ Catback Exhaust Built for Daily Street Sound

A flat-four BRZ feels better when the rear section breathes cleaner and the sound has some bite without turning every drive into a headache. This Flashark Subaru BRZ catback exhaust is built for drivers who want a sharper tone, cleaner rear-end styling, and a more open exhaust path while keeping the factory catalytic converter in place.

The system is designed for listed 2013-2020 Subaru BRZ models with the 2.0L FA20 engine and 2022-2024 Subaru BRZ models with the 2.4L FA24 engine. It is a cat-back exhaust, so it focuses on the mid-pipe and muffler section behind the catalytic converter. That makes it a practical upgrade for a stock or lightly modified BRZ where sound, appearance, and flow matter more than tearing apart the whole exhaust system.

Specifications

Key Features

• BRZ-focused cat-back upgrade: Built for listed Subaru BRZ coupe applications with factory-style rear exhaust routing.
• Stainless steel construction: Designed for heat resistance, daily use, and a cleaner look under the car.
• Mirror-polished finish: Helps the system look sharper from the rear and underneath the vehicle.
• Mandrel-bent pipe design: Helps maintain smoother exhaust flow through bends compared with crushed or sharp-bend tubing.
• CNC-machined flanges: Helps improve connection quality at the exhaust joints when installed on the correct vehicle.
• N1-style muffler layout: Gives the BRZ a more aggressive tone than the quiet factory muffler without changing the catalytic converter.
• Multiple tip options: Choose Single Burnt Tip, Dual Burnt Tip, or Dual Polished Tip depending on the look you want.
• Direct bolt-on design: No cutting or welding is normally required on a listed factory-layout BRZ, though rusty hardware can make installation harder.

Cat-Back Design And Sound Character

This is a cat-back exhaust system, not an axle-back and not a full exhaust package. It replaces the exhaust section behind the catalytic converter, including the rear exhaust path and muffler area. It does not replace the headers, downpipe, test pipe, front pipe, or catalytic converter.

Sound-wise, expect a deeper and more noticeable tone than the factory BRZ muffler. The N1-style muffler layout gives the car a more aggressive rear note, especially during cold start and throttle input. Cabin volume can vary by tip choice, existing exhaust parts, engine condition, and how tightly the system is installed. A leak at a flange can make even a good system sound bad, so take your time lining it up.

Tip Options And Rear-End Look

The tip choice changes the personality of the car more than many people expect. The single burnt tip gives the BRZ a more aggressive N1-style appearance. Dual burnt tips add symmetry with a stronger color accent. Dual polished tips look cleaner and more restrained, which fits a street build that does not need to shout from twenty feet away.

Performance Expectations

On many stock or lightly modified BRZ setups, a cat-back exhaust like this may support an estimated gain of about 5-10 HP. With supporting mods, a healthy engine, and proper ECU calibration, around 8-12 HP may be possible. Treat those numbers as a realistic range, not a guaranteed dyno sheet.

Actual results depend on vehicle condition, existing modifications, ECU strategy, fuel quality, air temperature, dyno type, installation quality, and whether the rest of the exhaust system is still stock. The biggest changes most drivers notice first are sound, throttle feel, and the car feeling less choked at the rear, rather than a massive seat-of-the-pants horsepower jump.
