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.

- 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.
| Tip Option | Best For | What To Know |
|---|---|---|
| Single Burnt Tip | Aggressive N1-style builds | More track-inspired look. Check bumper and diffuser clearance. |
| Dual Burnt Tip | Balanced rear look with a stronger visual accent | Good choice if you want symmetry and a sportier finish. |
| Dual Polished Tip | Cleaner daily street appearance | Less flashy than burnt tips while still giving the BRZ a cleaner rear profile. |
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.

Subaru BRZ Catback Exhaust Questions Before You Buy
Q1: Will this catback exhaust fit my 2013 Subaru BRZ?
A1: Yes, this listing includes 2013 Subaru BRZ models with the factory-equipped 2.0L FA20 engine and coupe body style. Confirm your vehicle still has the factory-style exhaust layout before ordering.
Q2: Will this fit a 2022, 2023, or 2024 Subaru BRZ?
A2: Yes, the verified fitment includes 2022-2024 Subaru BRZ models with the 2.4L FA24 engine. Check the rear bumper and any aftermarket diffuser before choosing the tip style.
Q3: Is 2021 Subaru BRZ fitment confirmed?
A3: The verified fitment table on this page lists 2013-2020 and 2022-2024 Subaru BRZ applications. Do not assume 2021 fitment unless customer support confirms it for your exact vehicle.
Q4: Is this a cat-back or an axle-back exhaust?
A4: This is a cat-back exhaust system. It replaces the exhaust section behind the catalytic converter, not just the small rear axle-back muffler section.
Q5: Is this a full exhaust system?
A5: No. This is not a full exhaust from the engine back. It does not include headers, downpipes, test pipes, front pipes, or catalytic converters.
Q6: Does this exhaust delete the catalytic converter?
A6: No. A cat-back exhaust installs after the catalytic converter. It is designed to improve the rear exhaust section while keeping the factory catalytic converter in place.
Q7: How much horsepower can this BRZ catback exhaust add?
A7: A realistic estimate is about 5-10 HP on many stock or lightly modified setups. Around 8-12 HP may be possible with supporting mods and proper tuning, but results vary by vehicle condition, ECU, temperature, dyno type, and installation quality.
Q8: Will the exhaust be too loud for daily driving?
A8: It will be louder and deeper than the stock BRZ exhaust. Most buyers choose it because they want more sound, but cabin volume depends on tip choice, other exhaust parts, road speed, and installation quality. Drivers who want near-stock quietness may prefer a milder exhaust setup.
Q9: Will this catback cause a check engine light?
A9: A cat-back exhaust alone should not normally trigger a check engine light because it does not remove the catalytic converter or oxygen sensor area. Leaks, existing sensor issues, wiring damage, or other modifications can still cause codes, so no exhaust should be treated as a zero-error guarantee.
Q10: Do I need a tune after installing it?
A10: A tune is not normally required for a basic cat-back installation on a stock-layout BRZ. Tuning may help when the car also has headers, intake, front pipe, or other supporting performance modifications.
Q11: Can I install this myself?
A11: Many experienced DIY owners can install a cat-back exhaust with proper tools, jack stands or a lift, and safe working space. Rusted bolts, damaged hangers, or aftermarket parts can make the job harder. When in doubt, use a professional exhaust shop.
Q12: Which tip option should I choose?
A12: Choose the Single Burnt Tip if you want a more aggressive N1-style look. Choose Dual Burnt Tip if you want a stronger visual accent with a balanced rear appearance. Choose Dual Polished Tip if you want a cleaner and more subtle street look.
Q13: Will the tips fit my rear bumper or diffuser?
A13: The system is intended for the listed BRZ factory-style rear layout, but aftermarket bumpers, diffusers, and previous exhaust work can change clearance. Check the tip opening area before installation, especially with the single-tip or dual-tip versions.
Q14: Does this fit Toyota GR86, Toyota 86, or Scion FR-S?
A14: Those cars share platform similarities with the Subaru BRZ, but this page should be treated as a Subaru BRZ listing. For Toyota GR86, Toyota 86, or Scion FR-S, use the correct vehicle-specific listing or contact support before ordering.
Q15: Is this exhaust street legal?
A15: This cat-back exhaust does not remove the catalytic converter, but street legality depends on local emissions and noise rules. Check your state, province, or local regulations before installing any performance exhaust on a road-driven vehicle.
