Built for Better Flow and a Deeper VQ Sound
The factory 370Z exhaust is comparatively quiet. Replacing the cat-back section changes the piping, muffler layout, and rear tips while leaving upstream components dependent on the selected configuration.
The dual mufflers and mandrel-bent tubing are intended to give the VQ37VHR a deeper, more aggressive tone during acceleration. Cold-start volume, cabin resonance, rasp, and cruising drone will vary with the catalytic converters, headers, test pipes, exhaust leaks, transmission, engine load, and other modifications.
Estimated output changes should be treated as setup-dependent. A gain in the 10–15 HP range may be possible on a suitable combination, but actual results depend on the complete exhaust system, engine condition, fuel, calibration, installation quality, and the method used to measure power. No fixed torque increase should be assumed without a vehicle-specific before-and-after test.

Catback, Axle-Back and Full Exhaust Explained
A catback exhaust replaces the exhaust path after the catalytic-converter connection and continues to the rear tips. It is more extensive than an axle-back or muffler replacement, which changes only the rear portion of the system.
This catback should not be confused with a complete header-to-tip exhaust package. Headers, catalytic converters, high-flow cats, test pipes, and other upstream parts are separate components unless they are specifically included in the selected configuration.
Terms such as “muffler 370Z,” “370Z exhaust,” and “370Z dual exhaust” are often used broadly, but the standard FLES08690 configuration is a dual catback system with rear mufflers and burnt tips.
What Is Included
- Flashark dual catback exhaust system for the selected configuration
- Gaskets
- Installation hardware
Package contents vary by selected configuration. Select the required SKU before ordering and compare every component with the vehicle before beginning installation.
Installation Notes
- Allow the complete exhaust system to cool before removal or adjustment.
- Support the vehicle using properly rated lifting equipment and approved lifting points.
- Inspect the existing catalytic-converter connections, flanges, studs, gaskets, hangers, and upstream exhaust parts before installation.
- Loosely assemble and align all sections before final tightening.
- Center both tips in the bumper openings and check clearance around the pipes, mufflers, braces, suspension, and rear fascia.
- Check for exhaust leaks after the first heat cycle and recheck the fasteners after the system has cooled.
- Lowered vehicles and cars with modified hangers or upstream exhaust parts may require additional alignment work.
Who This Exhaust Is For
- 370Z owners who want a dual cat-back layout rather than a muffler delete or single-exit system.
- Drivers looking for a deeper, more noticeable exhaust tone during acceleration.
- Owners who prefer the appearance of large dual burnt tips.
- Cars retaining a compatible factory-style upstream exhaust layout.
- Owners prepared to check alignment, tip position, clearances, and leaks during installation.
Who Should Choose a Different Setup
- Drivers who want factory-level sound or the quietest possible highway experience.
- Owners who require a guaranteed drone-free, rasp-free, or fixed-decibel exhaust.
- Vehicles whose year, engine, body configuration, or existing exhaust layout does not match the listed fitment.
- Owners looking only for an axle-back, muffler, resonated touring system, header, test pipe, or complete header-to-tip package.
- Drivers who require a product-specific street-use, emissions, or sound-compliance certification.
Emissions, CEL and Street-Use Notice
Cat-back configuration: The standard cat-back section is installed behind the catalytic-converter connection. Do not treat this as a guarantee that a modified vehicle will remain free of warning lights or pass local inspections.
Exhaust leaks, damaged sensors, test pipes, high-flow catalytic converters, headers, tuning changes, and other upstream modifications can affect CEL behavior, exhaust odor, sound, and emissions compliance.
Check local noise and emissions requirements before road use. A product should not be considered street legal solely because it is described as a cat-back exhaust.

Nissan 370Z Z34 Dual Catback Exhaust FAQs
Q1: Does this exhaust fit every 2009–2020 Nissan 370Z?
A1: The listed application is the 2009–2020 Nissan 370Z Z34 with the 3.7L VQ37VHR V6 in a factory-original exhaust configuration. Check the selected variant, body configuration, trim, and existing exhaust parts before ordering.
Q2: Does it fit the 2012 Nissan 370Z Sport?
A2: A 2012 370Z Sport falls within the listed year range, but the engine, body configuration, selected variant, and upstream exhaust layout must still match. Check fitment before ordering rather than relying on the trim name alone.
Q3: Is NISMO fitment the same as the Base, Sport or Touring model?
A3: NISMO bumper clearance and factory exhaust layout should be checked separately. Do not assume fitment from the shared Z34 chassis code alone.
Q4: Does it fit both the 370Z Coupe and Roadster/Convertible?
A4: Check body configuration before ordering. Roadster/Convertible and NISMO applications should be matched to the selected configuration and existing exhaust layout.
Q5: Is this a catback, axle-back or full exhaust system?
A5: FLES08690 is a dual catback exhaust. It replaces more of the rear exhaust path than an axle-back or muffler replacement, but it does not include headers or other upstream components unless they are listed in the selected configuration.
Q6: Will this work with the factory catalytic converters?
A6: The standard cat-back configuration connects behind a compatible factory-style catalytic-converter layout. Modified cats, test pipes, headers, flanges, or Y-pipes can change alignment and installation requirements.
Q7: Will a catback exhaust cause a Check Engine Light?
A7: A cat-back system does not replace the factory catalytic converters by itself, but no modified exhaust should be treated as guaranteed CEL-free. Leaks, damaged sensors, test pipes, high-flow cats, headers, and other upstream changes can trigger warning lights.
Q8: Does the 370Z need a tune after installing this catback?
A8: A tune is not included with the exhaust. Cars with test pipes, high-flow cats, headers, large-diameter intakes, or other airflow changes should be evaluated as a complete combination by a qualified tuner.
Q9: How much horsepower will it add?
A9: A 10–15 HP change may be possible on a suitable combination, but the result depends on the full exhaust setup, engine condition, fuel, calibration, installation quality, and measurement method. A catback alone should not be purchased on the expectation of a guaranteed power number.
Q10: How will it sound compared with the stock 370Z exhaust?
A10: Expect a deeper and more aggressive exhaust note, especially during acceleration. Cold-start volume and cruising sound depend on the catalytic converters and other exhaust components installed on the vehicle.
Q11: Is this exhaust guaranteed to have no drone or rasp?
A11: No fixed drone or rasp level can be guaranteed. Engine load, cruising rpm, catalytic converters, test pipes, leaks, cabin configuration, and other modifications all affect the sound heard inside and outside the car.
Q12: Are the 4.5-inch burnt tips included?
A12: The standard dual catback configuration uses dual 4.5-inch slanted burnt tips. Align both sides before final tightening to keep the tips centered in the bumper openings.
Q13: What hardware is included?
A13: Gaskets and installation hardware are included with the catback system. Package contents vary by selected configuration, so match every component to the selected SKU before installation.
Q14: Can I install it at home?
A14: Installation requires safe vehicle lifting, removal of the original exhaust, alignment of multiple sections, leak checks, and adequate clearance around the body and suspension. Use a qualified exhaust shop if you do not have the lifting equipment or experience to complete those steps safely.
Q15: Who should not buy this exhaust?
A15: Choose another setup if you need factory-level sound, a guaranteed drone-free result, a resonated touring system, an axle-back only, a confirmed NISMO/Roadster application, or product-specific street-use and sound certification.
