Design Inspiration: Evolution MotorSports stainless steel headers are meticulously engineered, tested and manufactured to improve performance for a wide variety of applications. Our design approach was not limited to building a “one size fits all” header for every application. Through our extensive testing and development process, we have created a variety of different headers that are properly sized for a wide range of power levels. Producing many different size headers is not cost effective or efficient from a manufacturing perspective; however, we believe that providing the most efficient and best designed headers for various power levels is far more important.
· Manufactured with a 2-piece header to head flange and internally welded like the OEM Porsche headers
· Reduces thermal stresses caused by expansion and contraction
· Minimizes risk of header cracking
· Argon purged for optimized weld quality / weld joint penetration
· Retains OEM ground clearance which minimizes the risk of damaged headers
· EVOMS headers provide an additional 1.25” of ground clearance as compared to other aftermarket headers
· CAD engineered, virtual and real world tested for optimum efficiency and performance
· Available in different primary tube sizes which have been developed specifically for a variety of power applications
Different diameter headers will change the exhaust velocity and overall flow from the heads to the turbochargers. Smaller headers can generate a quicker boost response, however, they can cause exhaust “choke” by not allowing enough exhaust volume to sustain higher power levels. Conversely, headers that are too large in diameter can reduce the amount of exhaust velocity causing slower turbocharger boost response and a loss in bottom end power. An optimized header for a specific power application will improve mid range power and torque throughout the entire rev range. Our header designs optimize the exhaust flow through the mandrel bent primary tubes and merge collectors. They have superior flow characteristics compared to the OEM header and are size specific depending on application and desired power. Our headers also maintain the stock amount of ground clearance which eliminates the risk of header damage from a low hanging primary tube which is common for most other aftermarket headers.
