Soul Performance Products - Competition Over Axle Pipes (718 GT4 RS)

Designed to Fit

• 2023+ Porsche Cayman GT4 RS

Product Details 

Soul's Competition Over Axle Pipes deliver the most significant sound potential from a single product by eliminating the redundant secondary cats and the empty particulate filters from the factory units. Our solution maintains full 3-inch diameter from flange to flange by using oval tubing to fit within the clearances of the car’s suspension and body. This is a unique and, we feel, necessary development to maximize the performance of the GT3-derived engine.

Streamlining our Competition Over Axle Pipe design also removes the significant heat soak that the factory units contained, but additional thermal solutions remain available.

Features:

•  Fits Porsche 718 GT4 RS with factory or upgraded headers or rear exhaust
• Weighs 13.3 lbs / 6 kg less than factory OAPs (11.65 lbs vs 25 lbs factory)
• No check engine light on North American cars, ECU tuning required for European cars

NOTE: Because of the increased output of the GT3-derived engine in 718 RS models, and the additional heat generated as a result, we strongly recommend applying a thermal management solution to Over Axle Pipe products to protect nearby components and body parts. We offer Jet-Hot ceramic coating in-house. This item includes this option by default. 

DEVELOPMENT: Soul Competition Over Axle Pipes deliver the most significant sound potential from a single product by eliminating the redundant secondary cats and the empty particulate filters from the factory units. Our solution maintains full 3-inch diameter from flange to flange by using oval tubing to fit within the clearances of the car’s suspension and body. This is a unique and, we feel, necessary development to maximize the performance of the GT3-derived engine.

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.
