OEM Downpipe vs Aftermarket Downpipe/Test Pipe: Nissan 350Z & Infiniti G35

The factory downpipe prioritizes emissions and long-term durability, often restricting exhaust flow. Aftermarket downpipes/test pipes deliver noticeable performance gains:

• Improved Exhaust Flow: Aftermarket designs remove unnecessary restrictions, allowing your VQ35DE engine to breathe more freely.
• Increased Horsepower and Torque: By reducing backpressure, engine efficiency improves, resulting in noticeable power gains.
• Enhanced Engine Sound: A freer-flowing exhaust produces a more aggressive and sporty exhaust note.
• Reduced Risk of Clogging: OEM catalytic converters may degrade or clog over time, limiting performance. Aftermarket test pipes eliminate this concern.

In short, upgrading your downpipes is a practical step for enthusiasts looking to maximize performance on the 350Z or G35 while enjoying a more engaging driving experience.

Downpipes vs Test Pipes: Why Flashark Combines Both for Nissan 350Z & Infiniti G35

Downpipes and test pipes serve distinct but complementary roles in a high-performance exhaust system:

• Downpipes: Connect directly to the exhaust manifold or turbo flange, guiding exhaust gases efficiently while maintaining structural integrity and durability.
• Test Pipes: Replace the restrictive factory catalytic converters entirely, allowing exhaust gases to flow freely for maximum horsepower, torque, and engine efficiency.

Flashark Downpipe/Test Pipes combine the best of both worlds:

• Freer-Flowing Exhaust: By eliminating the restrictive catalytic converters, Flashark pipes reduce exhaust drag, allowing your VQ35DE engine to breathe more efficiently.
• Performance Gains: This upgrade can result in noticeable horsepower and torque improvements, particularly at higher RPMs, enhancing overall engine performance.
• Reduced Maintenance Risk: Removing the factory catalytic converters lowers the risk of clogging or failure over time, potentially reducing long-term maintenance costs.
• Track and Street Ready: Designed for high-performance applications, these pipes are ideal for both track enthusiasts and drivers looking to optimize everyday driving performance.
• Precision Construction: TIG-welded 16-gauge T-304 stainless steel with CNC-machined flanges ensures durability, proper fitment, and resistance to heat and corrosion.

In short: Flashark Downpipe/Test Pipes act as a hybrid solution, combining the efficient exhaust routing of a downpipe with the unrestricted performance of a test pipe—delivering improved power, torque, and engine efficiency for your 2003-2006 Nissan 350Z or Infiniti G35.

Vehicle Overview: 2003-2006 Nissan 350Z & Infiniti G35

Both the 350Z (Z33) and G35 (V35) are powered by the VQ35DE 3.5L V6 engine, known for smooth power delivery and tuning potential. The 350Z is a driver-focused sports coupe, while the G35 combines luxury with performance. Both respond exceptionally well to exhaust upgrades, making Flashark downpipes/test pipes the perfect performance enhancement.

FAQ

Q1: Do G35/350Z test pipes or downpipes increase horsepower?

Yes, aftermarket test pipes and downpipes significantly increase horsepower. On average, a high-performance G35/350Z downpipe or test pipes can add 10 to 20 horsepower. The gains are especially noticeable at higher RPMs, enhancing overall performance on your VQ35DE engine.

Q2: Will installing G35/350Z test pipes or a downpipe make my car louder?

Yes, installing G35/350Z test pipes or downpipes provides a more aggressive and pronounced exhaust note. Flashark pipes reduce backpressure, allowing for smoother exhaust flow and a louder, sportier sound compared to the stock exhaust system.

Q3: Will installing a G35/350Z downpipe or test pipes void my warranty?

No, installing aftermarket G35/350Z downpipes or test pipes does not void your vehicle’s warranty. The Magnuson-Moss Warranty Act protects your warranty even when high-quality aftermarket parts like Flashark are installed.

Q4: What is the difference between a downpipe and a test pipe?

Downpipes guide exhaust gases efficiently from the manifold while maintaining catalytic converter compatibility. Test pipes remove catalytic converters entirely for maximum flow and performance. Flashark downpipes/test pipes combine both benefits, improving power, torque, and exhaust sound.

Q5: Are Flashark downpipes/test pipes legal for street use?

Flashark downpipes/test pipes are designed for high-performance and track use. Removing catalytic converters may not comply with emissions regulations in some states. Always check your local laws before installing for street use.

Q6: How easy is it to install Flashark downpipes/test pipes on a 350Z or G35?

Flashark pipes feature direct-fit CNC flanges and include all necessary gaskets and bolts. Professional installation is recommended for optimal fit and performance, but experienced enthusiasts can install them with standard tools.

Q7: Will I need ECU tuning after installing downpipes/test pipes?

For stock naturally aspirated 350Z and G35 setups, ECU tuning is typically not required. For forced induction or heavily modified vehicles, tuning may be beneficial to optimize air/fuel ratios and maximize performance.

Q8: What materials are Flashark downpipes/test pipes made from?

Flashark downpipes/test pipes are constructed from 16-gauge T-304 stainless steel with mandrel bends and TIG-welded joints, ensuring durability, corrosion resistance, and long-lasting performance.

Q9: Do these pipes improve throttle response?

Yes, by reducing backpressure and improving exhaust flow, Flashark downpipes/test pipes can enhance throttle response and acceleration, especially at higher RPMs, making your 350Z or G35 feel more responsive.

Q10: What’s included with the Flashark downpipes/test pipes?

Each set includes two downpipes/test pipes, all necessary gaskets, and mounting bolts for a complete, ready-to-install upgrade for your 2003-2006 Nissan 350Z or 2003-2007 Infiniti G35.
