2013–2024 Subaru BRZ FA20 & FA24 Catback Exhaust
The 2013–2024 Subaru BRZ keeps a balanced boxer-four and factory catalytic converter; this Flashark catback exhaust replaces the section behind the catalytic converter for a deeper note, cleaner rear styling, and a more open exhaust path on listed coupe applications with the 2.0L FA20 (2013–2020) or 2.4L FA24 (2022–2024) engine. The system is offered in three tip options: Single Burnt Tip, Dual Burnt Tip, and Dual Polished Tip.

Key Features
- Catback Section, Not Full Exhaust: Replaces the mid-pipe and rear muffler section behind the factory catalytic converter; headers, downpipe, test pipe, front pipe, and catalytic converter are not included or replaced.
- 201 Stainless Steel Construction: 2.36 in OD main tubing in 201 stainless steel for the listed BRZ coupe exhaust path, with mandrel-bent bends to keep flow smoother through curves.
- Three Tip Options for the Same Application: Single Burnt Tip, Dual Burnt Tip, and Dual Polished Tip use the same BRZ catback fitment, so changing tip style does not change the adapter or hanger setup.
- Dual Exit vs Single Exit Difference: Dual-tip SKUs (FLES08145 / FLES08146) include dual rear-exit piping with clamps for two tip outlets; Single-tip SKU (FLES08147) uses single rear-exit piping without clamps.
- Bolt-On With No Cutting on Listed BRZ: Installs behind the catalytic converter on listed 2013–2020 (FA20) and 2022–2024 (FA24) BRZ coupe applications without cutting the factory exhaust; rusty hardware can lengthen installation time.
- Retains Factory Catalytic Converter: Because the system mounts after the catalytic converter, the factory catalytic converter stays in place; oxygen sensors and the factory emission layout are not relocated.
- Resonator Included Across All Three SKUs: Each variant ships with one resonator, so exhaust note is shaped at the source rather than relying on the factory mid-pipe resonator alone.
Who This Kit Is For
This kit is built for BRZ owners who want a more aggressive exhaust note and a cleaner rear-end look on a stock or lightly modified BRZ coupe, without removing the factory catalytic converter. It targets drivers who already understand that a cat-back only addresses the section behind the catalytic converter and who want a direct bolt-on install on a factory-style exhaust layout. Drivers who need a full exhaust package, header-back build, or track-only setup should look at a different product line.
Tip Style Comparison
| Variant | SKU | Look | Best For | What To Check |
|---|---|---|---|---|
| Single Burnt Tip | FLES08147 | Single 4 in burnt tip, offset rear exit | Track-inspired N1-style look with a single 4 in burnt tip | Confirm rear bumper and aftermarket diffuser clearance on the tip side |
| Dual Burnt Tip | FLES08145 | Dual 4 in burnt tips, balanced rear exit | Symmetric look with a deeper visual accent from the burnt finish | Confirm both tip cutouts clear the rear bumper opening |
| Dual Polished Tip | FLES08146 | Dual 4 in polished tips, balanced rear exit | Cleaner daily street look without the burnt-finish coloring | Confirm both tip cutouts clear the rear bumper opening |
Check Before Ordering
- Confirm model year falls within 2013–2020 or 2022–2024; 2021 model-year BRZ is not confirmed by this listing.
- Confirm the vehicle has the 2.0L FA20 (2013–2020) or 2.4L FA24 (2022–2024) boxer-four engine and RWD coupe body style.
- Confirm the factory catalytic converter, oxygen sensors, and front exhaust are still in factory layout; modified mid-pipes or removed catalytic converters change the install.
- Measure the rear bumper tip cutout and any aftermarket diffuser against the chosen tip style (single 4 in offset or dual 4 in balanced) before ordering.
- This listing covers the Subaru BRZ only; Toyota GR86, Toyota 86, and Scion FR-S use a separate vehicle-specific listing.

2013–2024 Subaru BRZ Catback Exhaust FAQs
Q1: Will this catback exhaust fit my 2013 Subaru BRZ?
A1: Yes. The verified fitment includes 2013 Subaru BRZ coupe models with the factory-equipped 2.0L FA20 boxer-four and RWD layout. Confirm the vehicle still has a factory-style exhaust layout, including the factory catalytic converter, before ordering.
Q2: Will this fit a 2022, 2023, or 2024 Subaru BRZ?
A2: Yes. The verified fitment includes 2022–2024 Subaru BRZ coupe models with the 2.4L FA24 boxer-four. Measure the rear bumper tip cutout and any aftermarket diffuser against the chosen tip style (single 4 in or dual 4 in) before ordering.
Q3: Is 2021 Subaru BRZ fitment confirmed?
A3: No. The verified fitment table on this listing covers 2013–2020 and 2022–2024 Subaru BRZ coupe applications. 2021 model-year BRZ is not confirmed by this listing. Contact service@flasharkracing.com with your VIN before ordering if your BRZ is a 2021 model.
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, including the mid-pipe and rear muffler section; it is not a small rear axle-back section replacement.
Q5: Is this a full exhaust system?
A5: No. This is not a full exhaust from the engine back. Headers, downpipes, test pipes, front pipes, and the catalytic converter are not included and are not replaced by this kit.
Q6: Does this exhaust delete the catalytic converter?
A6: No. The cat-back mounts after the factory catalytic converter, which stays in place. Oxygen sensors and the factory emission layout are not relocated.
Q7: Will this catback exhaust change the sound?
A7: Yes. Each variant includes a resonator and either a single or double muffler layout, so the exhaust note is deeper and more noticeable than the factory BRZ muffler. Cabin volume can vary by tip choice, vehicle condition, and how tightly the system is installed; a leak at a flange can make any system sound worse, so follow the torque sequence and check the flanges after the first heat cycle.
Q8: Will this catback cause a check engine light?
A8: A cat-back installed behind the catalytic converter, with oxygen sensors and the catalytic converter in factory position, should not normally trigger a check engine light on a stock BRZ. Leaks, existing sensor issues, wiring damage, or other modifications can still set codes, so no exhaust should be treated as a zero-error guarantee.
Q9: Do I need a tune after installing it?
A9: A tune is not normally required for a basic cat-back install on a stock-layout BRZ. Tuning may help when the car also has headers, intake, front pipe, or other supporting performance modifications, but it is not part of this kit.
Q10: Can I install this myself?
A10: Many experienced DIY owners can install this cat-back with proper tools, jack stands or a lift, and safe working space. Rusted bolts, damaged hangers, or previous exhaust work can lengthen the job. When in doubt, use a professional exhaust shop.
Q11: Which tip option should I choose?
A11: Choose the Single Burnt Tip (FLES08147) if you want a more aggressive N1-style single-tip look with a burnt finish. Choose the Dual Burnt Tip (FLES08145) if you want a symmetric dual-tip look with a burnt finish and a deeper visual accent. Choose the Dual Polished Tip (FLES08146) if you want a cleaner daily street look without the burnt coloring. Tip style does not change the BRZ fitment; it only changes the rear-end look.
Q12: Will the tips fit my rear bumper or diffuser?
A12: The system is designed for the listed BRZ factory-style rear layout, but aftermarket bumpers, diffusers, and previous exhaust work can change clearance. Measure the tip cutout and check the rear bumper opening before installation, especially with the single-tip variant (FLES08147) and dual-tip variants (FLES08145 / FLES08146).
Q13: Does this fit Toyota GR86, Toyota 86, or Scion FR-S?
A13: No. Those cars share platform similarities with the Subaru BRZ, but this listing is for the Subaru BRZ only. Use the Toyota GR86, Toyota 86, or Scion FR-S vehicle-specific listing, or contact service@flasharkracing.com before ordering.
Q14: How much horsepower can this BRZ catback exhaust add?
A14: The largest changes most drivers notice are sound, throttle feel, and reduced back-pressure at the rear, not a hard-and-fast seat-of-the-pants horsepower jump. Power changes depend on the rest of the exhaust, ECU strategy, fuel, intake air temperature, dyno type, and installation quality, and are not part of this kit's published specifications.
Q15: Is this exhaust street legal?
A15: This cat-back 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.
