The Nissan 350Z is a beloved sports car known for its sleek design and impressive performance. One popular modification among enthusiasts is the installation of high flow catalytic converters, particularly those from Flowmaster. In this article, we will explore the real-world performance gains achieved by installing Flowmaster high flow cats on a 350Z.
Understanding High Flow Catalytic Converters
High flow catalytic converters are designed to increase exhaust flow, which can lead to improved engine performance. Unlike stock cats, which are built to meet strict emissions standards, high flow cats prioritize performance. They feature less restrictive designs and materials that allow for better exhaust gas evacuation.
Benefits of Installing Flowmaster High Flow Cats
Upgrading to Flowmaster high flow cats can offer several benefits for 350Z owners looking to enhance their vehicle’s performance. Some of the key advantages include:
- Increased Horsepower: Flowmaster high flow cats can help unlock additional horsepower by reducing back pressure in the exhaust system.
- Improved Torque: Enhanced exhaust flow can lead to better torque delivery, particularly in the mid-range RPMs.
- Better Sound: High flow cats can provide a more aggressive exhaust note, enhancing the overall driving experience.
- Weight Reduction: Many aftermarket high flow cats are lighter than stock units, contributing to a lower overall vehicle weight.
Real-World Performance Gains
To understand the actual performance improvements from installing Flowmaster high flow cats, we can look at some real-world examples. Many 350Z owners have reported noticeable gains in both horsepower and torque after making this modification.
Dyno Testing Results
Dyno testing is a common method used to measure the performance of a vehicle before and after modifications. Several 350Z owners have shared their dyno results following the installation of Flowmaster high flow cats:
- One owner reported a gain of 15 horsepower and 10 lb-ft of torque after installing the high flow cats.
- Another owner experienced a 20 horsepower increase, along with a more responsive throttle.
- Some dyno tests have shown gains of up to 25 horsepower with additional supporting modifications.
Installation Process
Installing Flowmaster high flow cats on a 350Z can be a straightforward process for those with basic mechanical skills. However, it is essential to follow the correct steps to ensure a proper installation. Here’s a brief overview of the installation process:
- Gather Necessary Tools: You will need basic hand tools, including wrenches, sockets, and a jack.
- Lift the Vehicle: Safely lift and secure the car using jack stands.
- Remove Stock Cats: Disconnect the stock catalytic converters from the exhaust system.
- Install Flowmaster High Flow Cats: Position the new cats and secure them in place.
- Reconnect Exhaust System: Reattach the exhaust system and check for leaks.
Considerations Before Installation
Before installing high flow cats, there are a few considerations to keep in mind:
- Emissions Compliance: High flow cats may not be street legal in all areas. Check local regulations to ensure compliance.
- Supporting Modifications: For optimal performance gains, consider pairing high flow cats with other modifications like a cat-back exhaust system and an ECU tune.
- Installation Costs: Factor in the cost of the high flow cats and any professional installation fees if you’re not doing it yourself.
Conclusion
Flowmaster high flow catalytic converters can provide significant performance gains for Nissan 350Z owners. With increases in horsepower, torque, and an enhanced exhaust note, these modifications can transform the driving experience. However, it is crucial to consider emissions regulations and the potential need for supporting modifications to maximize benefits. Overall, for those looking to enhance their 350Z, Flowmaster high flow cats are a worthwhile investment.
