Test Pipes are primarily used in place of catalytic converters and are designed to completely eliminate catalytic converters to reduce exhaust drag and increase power output, typically used in track and high performance applications.
For the 2008-2018 Nissan 370Z, test pipes eliminate the restrictive catalytic converters, allowing for a more free-flowing exhaust. This modification can lead to significant gains in horsepower and torque, enhancing the overall performance of these engines. Without catalytic converters, there's less concern about clogging or failure of these components, leading to potentially lower maintenance costs over time.

Q&A
1. Do Test Pipes or Downpipes add horsepower?
Yes. Both Test Pipes and Downpipes, like the FLASHARK G37 Test Pipes and 370Z Downpipe, are designed to increase horsepower. By improving exhaust flow and reducing restrictions, they can add 10 to 20 horsepower on average, with noticeable gains during high-performance driving.
2. Will Test Pipes or Downpipes make my car louder?
Absolutely. Installing Test Pipes or Downpipes will create a more aggressive exhaust note compared to stock systems. The FLASHARK Test Pipes/Downpipe reduces backpressure, resulting in a louder, freer-flowing exhaust sound that's perfect for performance enthusiasts.
3. Will installing Test Pipes or Downpipes void my warranty?
No. Installing aftermarket Test Pipes or Downpipes will not void your vehicle's entire warranty. If you’re in the United States, the Magnuson Moss Warranty Act ensures your warranty remains intact unless the modification is proven to directly cause a failure.
Fitment:
- 2009-2018 Nissan 370Z Z34
- For All Infiniti Q50/Q60 Models with 3.7L Engine (does not fit 2.0 or 3.0t models)
- Note: Also fits Infiniti G37. See full compatibility here.
Q1: Will these infiniti g37 & nissan 370z downpipe/test pipes fit my specific vehicle model?
A1: Yes, these Flashark premium downpipe/test pipes are engineered for the popular VQ37VHR 3.7L V6 platform. They offer a precise direct fitment for the 2009-2018 Nissan 370Z (Z34) Coupe and Roadster, the 2008-2013 Infiniti G37 (Coupe, Sedan, and Convertible), as well as the 2008-2013 g37x test pipes AWD configurations and newer Infiniti Q50/Q60 models with the 3.7L engine. Please note they do not fit the 2.0T or 3.0T engine options.
Q2: What is the primary performance benefit of swapping out my factory catalytic converters for aftermarket g37 test pipes?
A2: Factory catalytic converters are notorious for being highly restrictive, which chokes your exhaust gas velocity. By switching to Flashark test pipes for g37, you completely remove these restrictive bottlenecks. This minimizes engine backpressure, enhances cylinder scavenging, and allows your 3.7L engine to breathe freely, typically delivering a noticeable increase of 10 to 20 horsepower and sharpening mid-to-high RPM throttle response.
Q3: Do you offer modular performance bundles such as a 2009–2013 nissan 370z g37 exhaust header+downpipe+y pipe package?
A3: Yes, absolutely! To provide maximum flexibility for your build and save you money, we offer several bundled variations directly on this product page. You can purchase the standalone 370z downpipe, an exhaust header + downpipe kit, a downpipe + y-pipe kit, or choose our ultimate comprehensive 2009–2013 nissan 370z g37 exhaust header+downpipe+y pipe package for a complete uncompromised high-flow exhaust system configuration.
Q4: What material construction ensures the structural durability of these z34 race downpipes?
A4: Flashark z34 race downpipes are engineered for harsh racing conditions and long-term durability. They are fabricated from high-quality, heavy-duty 16-gauge T-304 stainless steel with a stunning mirror-polished finish. All structural joints are meticulously TIG welded to eliminate any risks of stress cracking, and the tubing features computerized mandrel bends for consistent airflow. Additionally, the CNC-machined flanges are chrome-plated to offer maximum sealing strength and anti-warping resistance.
Q5: Will installing this z34 test pipe kit require any additional fabrication or trips to the hardware store?
A5: Not at all. We believe in providing a true 100% direct bolt-on experience right out of the box. Every single kit includes 2 high-flow performance downpipes, 4 high-temperature flange gaskets (2 heavy-duty 3-bolt gaskets and 2 precision-fit 2-bolt gaskets), and 10 pieces of professional-grade mounting hardware so you have everything required for a seamless install.
Q6: How will upgrading to a free-flow nissan 370z downpipe alter my vehicle's exhaust note?
A6: Upgrading your car with a Flashark nissan 370z downpipe drastically improves its acoustic signature. It eliminates the muffled, choked tone of factory components and introduces a crisp, aggressive, and beautifully deep performance growl under acceleration. It provides a race-inspired roar when you step on the gas while maintaining a refined, drone-free character at cruising speeds.
Q7: Can these downpipes be used if I am configuring a g37 sedan test pipes layout?
A7: Yes, they fit perfectly. This performance upgrade is universally cross-compatible across body styles. Whether you are building a g37 sedan test pipes setup or working on a coupe model, the downpipes line up perfectly with your vehicle's factory exhaust manifolds or aftermarket headers, as well as the factory or aftermarket Y-pipe assembly.
Q8: Do these performance 370z test pipes include integration bungs for factory oxygen sensors?
A8: Yes, they do. To ensure completely reliable factory integration, our 370z test pipes feature integrated, pre-welded O2 sensor bungs. This allows you to easily screw your original oxygen sensors back into their correct factory locations to monitor exhaust parameters accurately without requiring any custom modification or sensor extension fabrication.
Q9: What type of replacement z34 exhaust gasket profile is provided in the box to guarantee an airtight seal?
A9: Every package includes robust, high-temperature multi-layer composite z34 exhaust gasket pairs tailored for our 2.50-inch inlet and outlet connections. These gaskets collapse smoothly under torque to form a highly reliable, completely airtight compression seal, protecting your vehicle against annoying post-installation exhaust leaks.
Q10: Is a custom ECU tune or a z34 flash mandatory immediately after bolting on this kit?
A10: While a custom ECU calibration or a performance z34 flash is always a fantastic way to maximize your air-fuel mixture efficiency and unleash every single ounce of horsepower from this infiniti g37 z34 test pipe downpipe high flow exhaust modification, it is not strictly mandatory for daily driving. Your vehicle's factory ECU can safely adapt to the increased airflow parameters immediately.
Q11: How do these standalone downpipe/test pipes for infiniti g37 & nissan 370z 2008-2018 compare to full a z34 resonated exhaust?
A11: Our downpipe/test pipes for infiniti g37 & nissan 370z 2008-2018 are designed to completely replace the most restrictive portion of the exhaust system to deliver raw power and throttle response. If you are looking to fine-tune the exhaust note or achieve a specific acoustic pitch like a full z34 resonated exhaust, we highly recommend combining these downpipes with our matching high-flow Y-pipes and catback systems available via our on-page bundles.
Q12: What type of product warranty and shipping timeline does Flashark offer for this kit?
A12: We stand behind our premium craftsmanship with an industry-leading Permanent Warranty covering any manufacturing or structural workmanship defects. Furthermore, Flashark provides 100% free shipping directly out of our regional warehouse network with a fast delivery time estimated in just 3 to 5 working days, ensuring your vehicle undergoes minimal downtime.
