Review DEMOTOR PERFORMANCE Nissan Z33 Infiniti 3.5l Stainless Headers fits 350Z G35 FX35 VQ35DE 2003–2006

Introducing the Demon Power R27364 Exhaust Header System, a game-changer for your Nissan 350Z Z33, Infiniti G35, and FX35 with the VQ35DE 3.5L engine (model years 2003-2006). This header system is not just an upgrade; it's a complete transformation, engineered to optimize power and performance, delivering an exhilarating driving experience.

The Demon Power R27364 Exhaust Header System is meticulously designed with premium T304 stainless steel, ensuring superior strength and durability. The headers feature a 4-1 design, which is crucial in minimizing exhaust gas turbulence and maximizing scavenging, resulting in improved combustion efficiency and horsepower gains.

The headers come with integrated collector design, which allows for a smoother and more efficient exhaust flow. This design also reduces the overall length of the header, resulting in a more compact installation. The exhaust gases exit the headers through 1.5-inch (38.1mm) primaries, which are larger than the stock primaries, allowing for better exhaust flow and an increase in horsepower.

The R27364 header system comes with welded-on OEM-style exhaust flanges, ensuring a direct bolt-on fitment to the factory catalytic converters and exhaust system. This not only simplifies the installation process but also maintains the factory emission system, making it a perfect choice for those who want to keep their vehicles street-legal while enjoying a performance boost.

One of the most significant advantages of the Demon Power R27364 Exhaust Header System is its ability to improve engine breathing and responsiveness. The headers' optimized design allows for a more efficient exhaust flow, resulting in quicker throttle response and a more engaging driving experience. The improved exhaust flow also results in a more powerful and distinctive engine note, adding to the overall thrill of driving your Nissan 350Z, Infiniti G35, or FX35.

Lastly, the R27364 header system is coated with a high-temperature ceramic coating. This coating not only protects the headers from the extreme heat but also provides a sleek, stylish finish. Moreover, the ceramic coating helps to insulate the headers, reducing the amount of heat transferred to the engine bay, which can lead to a cooler operating temperature and improved performance.

In conclusion, the Demon Power R27364 Exhaust Header System is a must-have upgrade for anyone looking to extract the maximum potential from their Nissan 350Z Z33, Infiniti G35, or FX35 with the VQ35DE 3.5L engine. It offers significant power gains, improved engine responsiveness, and an exhilarating driving experience, all while maintaining a direct bolt-on fitment to the factory exhaust system.
