Description
Looking for the best headers for Porsche 911 991.2 GT3?
Evolution Header Sets convert the slip-on exhaust into a complete system designed to give noticeably increased power at higher revs.
Handcrafted titanium headers incorporate 100 cpsi sports catalytic converters and side mufflers, both designed to increase power and torque.
The Evolution Header Set utilizes integrated catalytic converters and the functionality of the exhaust valves to deliver an out-and-out attack on the senses.
With the valves in the open position, it delivers a sportier and hard-hitting sound, but also has the option of a lower sound level when the valves are closed, perfect for use in more everyday locations.
Offering an increased weight savings in the area behind the engine and the rear axle, the reduction will enhance the handling and improve performance.
Muffler and tips pictured are not included
