For the standard 718 GT4, we offered a catted and catless solution for a header replacement. But to follow suit with the GT4 RS that would introduce necessary compromises, we didn’t do it. Our Competition Headers maximize the design potential of that section of the GT4 RS, utilizing all the space available for longer tubing and an expanded merge collector to meet the 3-inch flow path of the Over Axle Pipes.
Our Competition Headers will deliver immediate increases in sound, power and response in an efficient and lightweight package.
DETAILS
+ Direct bolt-on installation, pairs with factory or upgraded Over Axle Pipes

+ All SOUL Performance Products exhaust components are backed by the industry’s first and finest Lifetime Warranty for both street and track use
+ Designed and built in-house at our Willow Grove, PA facility
CONSTRUCTION: Each set is assembled in-house in the USA out of mandrel bent, thick wall .065″” T304L stainless steel. Back-purged TIG welding (with ARCAL™ Prime argon gas) ensures proper weld penetration and longevity – crucial for durability on the track. Our cast head flanges allow for a smooth transition from exhaust ports into the runners. Water jet cut exhaust flanges are made to ISO 9001:2015 standards with tolerances of +/- 0.003 inches for extreme precision. We fabricate these headers using thick gauge aluminium fixtures which act as a great heat sink during the welding process and prevent warping not only of our products but the fixtures themselves to ensure perfect fitment.
BOLT ON AND GO: Every set is rigorously quality-checked prior to shipping and then foam packed to ensure your order arrives in perfect condition. New high-grade hardware and OEM three-bolt gaskets are included.
