The DC Sports 4-2-1 one-piece header eliminates the two middle flanges and is up to two pounds lighter than the two-piece header.
The DC Sport 4-2-1 header combines clean looks, performance, lighter weight, and superior ground clearance.
DC Sports utilized Computer Aided Design (CAD) to develop these headers, which are more efficient at scavenging exhaust gasses than the factory stoc...
Long tube design for high RPM flow. Stepped design for increased torque gains.
Ideal for road racing and all motor drag racing. Race cars with high lift cams and high RPM rev range....
Thickest and strongest materials used by any turbo manifold manufacturer, 8 gauge forged stainless steel.
Equal length designs, increase spool time by approximately 800 rpm, huge midrange and peak power and torque gains.
Equal long-radius bends result in equal frictional flow coefficients, balancing flows from runner to runner.
Low angle merge collector designs minimize collector fluid frict...

This product has been developed in response to considerable demands for a balance between peak power and torque.
In its development, Spoon Sports has implemented all possible combinations of pipe diameter, assembly rotation, and other similar factors in exhaustive engine-bench, flow-bench, and actual driving tests.
Spoon Sports Header Furthermore, without any reduction in low speed ...
A bench tested (Equal length 4-2-1+ Taper) Design. Taper design is adopted from
feedback from both racing and dyno bench testing. Race type high flow junction. Each
section of the manifold has optimized pipe lengths, diameters,and angles as well as
high flow junctions. Made of light weight stainless steel for both durability and
looks. Flange manufactured by high precision CNC machine. (exhaus...
