Review MANLEY Extreme Duty Exhaust Valves

The Manley 11741-8 Extreme Exhaust Valves are a high-performance upgrade for your engine's exhaust system. These valves are specifically designed for high-performance and racing applications, where the demands on the exhaust valves are greater than in standard production engines.

The Extreme Exhaust Valves are made from high-strength, heat-treated steel, which provides superior strength and durability compared to standard valves. The valve stems are machined to a precise diameter and surface finish, ensuring a snug fit in the guide and minimizing valve float.

The valves feature a unique design with a large 31mm diameter, which provides increased flow area and improved exhaust gas scavenging. This results in better engine breathing and increased power output. The valves also have a high lift capacity, with a maximum lift of 11.5mm, which is crucial for high-performance engines that require aggressive exhaust valve movement.

The Manley Extreme Exhaust Valves also feature a unique design with a roller tip, which reduces friction and wear on the valve tips. This results in longer valve life and improved engine performance. The roller tips also provide smoother valve operation, which reduces engine noise and vibration.

The valves come with a set of Manley 11551-8 Titanium Retainers, which provide superior strength and durability compared to standard steel retainers. The titanium retainers also reduce weight, which can help improve engine performance by reducing rotating mass.

The Manley 11741-8 Extreme Exhaust Valves are a high-quality, high-performance upgrade for your engine's exhaust system. They are designed to provide superior strength, durability, and flow capacity, making them an ideal choice for high-performance and racing applications. With their large diameter, high lift capacity, and roller tip design, these valves offer significant performance benefits over standard exhaust valves.

Manley 11741-8 Extreme Exhaust Valves are aftermarket exhaust valves designed for high performance applications. These valves offer several benefits, but like any purchase, they come with their share of pros and cons.

1. Enhanced Performance: Manley Extreme Exhaust Valves are made from high-quality materials, including stainless steel valves and titanium retainers, which help improve engine performance by reducing valve train friction and heat.

2. Durability: These valves are designed to withstand the rigors of high-performance applications and are built to last longer than OEM valves.

3. Improved Flow: The larger valve sizes and improved design of these valves help improve airflow, which can lead to increased horsepower and torque.

4. Customizability: Manley offers a variety of options for these exhaust valves, including different sizes, materials, and cam profiles, allowing customers to customize their setup to their specific needs.

1. Cost: Manley Extreme Exhaust Valves are more expensive than OEM valves due to their high-quality materials and customizable options.

2. Installation Complexity: Installing aftermarket exhaust valves can be a complex process and may require specialized tools and knowledge.

3. Potential for Leaks: Although rare, there is a possibility of leaks occurring during installation or due to the use of aftermarket parts.

4. Lack of OEM Warranty: Aftermarket parts like Manley Extreme Exhaust Valves do not come with the same level of warranty coverage as OEM parts.

Manley 11741-8 Extreme Exhaust Valves offer several benefits for high-performance applications, including enhanced performance, durability, improved flow, and customizability. However, they come with some drawbacks, such as cost, installation complexity, potential for leaks, and lack of OEM warranty. Ultimately, the decision to purchase these valves depends on the specific needs and budget of the customer.

If you are looking to maximize engine performance in a high-performance application, Manley Extreme Exhaust Valves can be a worthwhile investment. However, it is important to carefully consider the potential costs, installation complexities, and risks before making a purchase. If you are unsure about the installation process or have concerns about leaks, it may be best to consult with a professional mechanic or performance specialist.
