- Mandrel-bent main piping: The listed piping construction distinguishes this assembly from the factory exhaust sections it replaces.

Catback, Axle-Back, and Full Exhaust: What This System Replaces
The base FLES08690 is a catback system with dual rear mufflers and burnt tips. It is not an axle-back or a single replacement muffler, and it should not be treated as a complete header-to-tip package.
Headers, test pipes, high-flow catalytic converters, and other upstream components are not part of the base catback configuration. The separately selectable 2009–2019 Catback + Catalytic Converter option is a different package and must be ordered by its own SKU.
What's Included
- Flashark dual catback exhaust system for the selected base configuration
- Gaskets
- Installation hardware
Package contents differ by selected configuration. Match the SKU on the order to the parts received before removing the original exhaust.
Who This Kit Is For
This base kit is intended for listed 370Z owners choosing a dual cat-back layout with rear mufflers and large burnt tips. Choose a different product if the purchase requires only an axle-back, a single muffler, a single-exit layout, or a complete header-to-tip package.
Check Before Ordering
- Select the exact SKU required; the base catback and the 2009–2019 Catback + Catalytic Converter option are different packages.
- Confirm the vehicle year, Z34 application, 3.7L VQ37VHR engine, body configuration, trim, and existing exhaust layout.
- Check NISMO and Roadster/Convertible applications separately rather than relying on chassis code alone.
- Inspect modified headers, catalytic converters, test pipes, Y-pipes, flanges, hangers, and lowered suspension for possible connection or clearance differences.
- Compare all received components with the selected SKU before installation.
- Check local noise and emissions requirements. The product type alone is not a street-use, emissions, or inspection certification.

2009–2020 Nissan 370Z Z34 Dual Catback Exhaust FAQs
Q1: What does the base FLES08690 fit?
A1: The base FLES08690 application is listed for 2009–2020 Nissan 370Z Z34 models with the 3.7L VQ37VHR V6 and a factory-original exhaust configuration. Confirm body style, trim, and existing exhaust parts before ordering.
Q2: Is the 2009–2019 Catback + Catalytic Converter option the same as the base catback?
A2: No. It is a separate selectable package with its own SKU and a 2009–2019 option label. Do not use the base catback's 2009–2020 range or package list to confirm the combination SKU.
Q3: Does this fit a 2012 Nissan 370Z Sport?
A3: The 2012 model year falls within the base system’s listed range, but the Sport trim name alone does not confirm the complete application. Verify the engine, body configuration, selected SKU, and existing exhaust layout.
Q4: Is NISMO or Roadster/Convertible fitment confirmed by the Z34 chassis code?
A4: No. Shared chassis terminology should not replace a configuration check. Confirm bumper clearance, body configuration, trim, and factory exhaust layout before ordering for these applications.
Q5: Is FLES08690 a catback, axle-back, or full exhaust?
A5: FLES08690 is listed as a dual catback exhaust system. It is not an axle-back or muffler-only replacement, and the base configuration does not include headers or other upstream parts.
Q6: Are catalytic converters included with the base FLES08690 catback?
A6: Catalytic converters are not listed as part of the base FLES08690 package. A separately selectable 2009–2019 Catback + Catalytic Converter package has its own SKU.
Q7: What tip configuration is listed for the base system?
A7: The base system is listed with two 4.5-inch slanted burnt tips. Align both sides and verify bumper clearance before final tightening.
Q8: What is included with the base catback?
A8: The page lists the dual catback system, gaskets, and installation hardware for the selected base configuration. Package contents vary by option, so compare the received parts with the ordered SKU before installation.
Q9: Will the exhaust sound exactly like the video on every 370Z?
A9: No fixed sound result should be assumed. Catalytic converters, headers, test pipes, leaks, transmission, engine load, and other vehicle changes can alter volume, tone, rasp, and cabin resonance.
Q10: Does installing this catback guarantee there will be no Check Engine Light?
A10: No CEL guarantee is provided. Leaks, damaged sensors, test pipes, high-flow catalytic converters, headers, and other upstream changes can affect warning-light behavior.
Q11: Does the product type guarantee emissions or street-use compliance?
A11: No. A catback description is not a product-specific street-use, emissions, sound, or inspection certification. Check the requirements that apply where the vehicle will be used.
Q12: What should be checked after installation?
A12: Check exhaust alignment, tip position, surrounding clearances, and leaks after assembly. Recheck the fasteners after the first heat cycle and after the system has cooled.
