Product Details

For the standard 718 GT4, Soul Performance offered both a catted and catless solution for a header replacement. But in order to follow suit with the GT4 RS that would introduce necessary compromises. For a transformative solution that still retains catalytic converters, Soul developed a Sport Header Package that combines our unrestricted Competition Headers with our Sport Cat Over Axle Pipes.

The 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 flowpath of the Over Axle Pipes, and the Sport Cat Over Axle Pipe with high-flow cats deliver tangible sound and performance gains as it replaces the empty particulate filter on the factory units.

Features:

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. Water jet cut flanges are made to ISO 9001:2015 standards with tolerances of +/- 0.003 inches for extreme precision. We fabricate these over axle pipes using thick gauge aluminum 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: Each set is rigorously quality-checked, tested in a fixture to guarantee fitment, and then foam packed to ensure they arrive in perfect condition. New high grade hardware is included for installation.

JET-HOT CERAMIC COATING: With superior thermal management and corrosion resistance properties that lower surrounding temperatures by up to 65%, increased protection from thermal oxidation, galvanic corrosion and the ability to withstand 1250°F surface temperatures, there is no question as to why Jet-Hot Extreme 1300 remains the industry leader in exhaust coatings. An improvement over standard heat shields, ceramic coating is done professionally by Jet-Hot on both the outside AND inside of the exhaust for the best possible heat management. By keeping the velocity of the exhaust high, these coatings actually cause your exhaust gases to flow faster and decrease thermal tumbling which leads to improved power as well. Ceramic coatings keep away oil, gas, salt, and other metal degrading materials that your parts come into contact with every day as an added benefit. Classic Polish is the default finish choice as it is the Extreme 1300 base coat appearance (and most effective without a color top coat) but color top coats are optional with an extended lead time and additional charge.
