Why Choose a Dual Exhaust System for Your G35 Sedan?

Enhanced Performance: Performance enhancement is one of the key reasons why G35 owners consider upgrading to a dual exhaust system. The original, factory-installed exhaust system in many cars, including the Infiniti G35, is often designed with cost-effectiveness and noise reduction in mind. This can sometimes restrict the engine's ability to breathe efficiently, limiting its overall power output. A high-quality dual exhaust system, on the other hand, is engineered to optimize exhaust gas flow. By providing a less restrictive pathway for exhaust gases to exit the engine, the dual exhaust system helps reduce backpressure. Backpressure occurs when the exhaust gases struggle to escape the engine cylinders, which can hinder the engine's ability to take in fresh air and fuel for the next combustion cycle. Reducing backpressure allows the engine to operate more efficiently, resulting in improved horsepower and torque. After installing a dual exhaust system, many G35 owners notice a tangible difference in their car's acceleration and overall responsiveness, particularly at higher RPMs. This is because the engine can expel exhaust gases more easily, allowing it to breathe more freely and generate more power. Moreover, some dual exhaust systems are designed with specific features, such as tuned resonators and optimized pipe diameters, to further enhance exhaust gas flow and maximize performance gains. These features work together to create a scavenging effect, where the exhaust pulses from one cylinder help draw out the exhaust gases from another cylinder, further improving engine efficiency and power output. The improved exhaust flow provided by a dual exhaust system can also contribute to better fuel economy in some cases. When the engine can breathe more easily, it doesn't have to work as hard to produce power, which can translate into reduced fuel consumption, especially during highway cruising. However, it's important to note that fuel economy gains may vary depending on driving habits and other factors.

Aggressive Sound: The sound of your car is also very important! The enhanced sound is a major draw for car enthusiasts looking to upgrade their exhaust system. The stock exhaust on the Infiniti G35 sedan, like many factory-installed systems, is designed to be relatively quiet and unobtrusive. While this may be suitable for everyday driving, it often lacks the sporty and aggressive tone that many drivers crave. A dual exhaust system can completely transform the sound of your G35, giving it a much more muscular and assertive exhaust note. The specific sound characteristics of a dual exhaust system can vary depending on several factors, including the design of the mufflers, resonators, and exhaust pipes, as well as the materials used in its construction. Some dual exhaust systems are designed to produce a deep, throaty rumble at idle and low RPMs, while others may offer a higher-pitched, more aggressive tone at higher RPMs. Many enthusiasts prefer a balanced sound that provides a noticeable improvement over the stock exhaust without being excessively loud or obnoxious. A well-designed dual exhaust system will typically enhance the natural sound of the engine, accentuating its sporty characteristics and providing a more engaging driving experience. The enhanced sound can also add to the overall sense of performance and excitement, making every drive feel more special. Moreover, the sound of a dual exhaust system can often be customized to suit individual preferences. Some manufacturers offer different muffler options or resonator configurations that allow drivers to fine-tune the exhaust note to their liking. This enables you to achieve the perfect balance of sound and performance for your G35 sedan. When choosing a dual exhaust system, it's important to consider the sound level and tone that you desire, as well as any noise restrictions in your local area. Some exhaust systems may be too loud for certain neighborhoods or driving environments, so it's essential to do your research and choose an option that meets your specific needs and preferences.

Aesthetics: The aesthetic appeal is yet another compelling reason why many G35 sedan owners opt for a dual exhaust system. The exhaust system is not just about performance and sound; it also plays a significant role in the overall look and style of the vehicle. The factory-installed exhaust system on the Infiniti G35 sedan is often hidden beneath the rear bumper and may not be particularly eye-catching. A dual exhaust system, on the other hand, can add a touch of sportiness and aggression to the rear of the car, enhancing its visual appeal. Most dual exhaust systems feature polished stainless steel exhaust tips that protrude from the rear bumper, adding a stylish and customized look. These exhaust tips come in a variety of shapes, sizes, and finishes, allowing you to choose an option that complements the overall design of your G35. Some popular exhaust tip styles include round, oval, rectangular, and even quad tips, which feature four separate outlets for an even more aggressive appearance. In addition to the exhaust tips, the exhaust pipes themselves can also be visible, depending on the design of the system. Some dual exhaust systems are designed with mandrel-bent pipes that are carefully routed to maximize exhaust flow and minimize restrictions. These pipes can be made from stainless steel or other high-quality materials and may feature a polished or brushed finish for added visual appeal. The overall aesthetic impact of a dual exhaust system can be quite significant, transforming the rear of your G35 from plain and understated to sporty and stylish. The enhanced appearance can also complement other modifications you may have made to your car, such as aftermarket wheels, body kits, or spoilers. When choosing a dual exhaust system for aesthetic purposes, it's important to consider the overall style and design of your G35, as well as your personal preferences. Some exhaust systems may be too flashy or aggressive for certain tastes, while others may be too subtle to make a noticeable difference. It's essential to find a balance that complements the overall look of your car and reflects your individual style.

Things to Consider Before Installing a Dual Exhaust

Fitment: When selecting a dual exhaust system for your Infiniti G35 sedan, ensuring proper fitment is absolutely crucial for a hassle-free installation and optimal performance. Fitment refers to how well the exhaust system is designed to integrate with the existing components of your vehicle, including the chassis, suspension, and other underbody elements. A poorly fitting exhaust system can lead to a host of problems, ranging from annoying vibrations and rattles to more serious issues such as exhaust leaks and damage to other parts of your car. To ensure proper fitment, it's essential to choose a dual exhaust system that is specifically designed for your Infiniti G35 sedan. Avoid universal or generic exhaust systems that may require extensive modifications to fit correctly. Look for reputable brands that have a proven track record of producing high-quality exhaust systems with precise fitment for specific vehicle models. Before making a purchase, carefully review the product description and specifications to confirm that the exhaust system is compatible with your G35's year, make, and model. Pay attention to any specific fitment notes or warnings, such as compatibility with certain trim levels or aftermarket modifications. It's also a good idea to read reviews and testimonials from other G35 owners who have installed the same exhaust system. Their experiences can provide valuable insights into the fitment quality and any potential challenges you may encounter during installation. When installing the dual exhaust system, carefully follow the manufacturer's instructions and use the correct hardware and tools.
