Porsche 718 GT4 RS / Spyder RS SOUL Race Exhaust Package

$5,290.00$7,865.00

Combining our Competition Over Axle Pipes with our Race Exhaust System eliminates the major bottlenecks in the GT4 RS exhaust flow and extracts the most sound and performance potential for the platform. Owing to the unique oval design of our Over Axle Pipes, this system runs a full 3 inches all the way through, ensuring that the 4.0-liter flat-six realizes its motorsports pedigree in every way.

DETAILS:

+  Fits Porsche 718 GT4 RS / Spyder RS with factory or upgraded headers (2022+)
+  Weighs about 20 lbs less than factory exhaust components (39.15 lbs vs 59 lb factory)
+  No check engine light on North American cars, ECU tuning required for European cars
+  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

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 or can recommend simple and effective exhaust wrapping options via DEI.

Description

DEVELOPMENT:  Borrowing its 4.0-liter flat-six from the 992 GT3 Cup, the 718 GT4 RS came delivered with serious motorsports pedigree. In order to satisfy worldwide regulations and meet production deadlines, certain components of the platform left performance and sound on the table. That’s what we’ve aimed to maximize.

 

Our Race Exhaust Package tackles the biggest bottlenecks we found in the factory exhaust system, those being the over axle pipes and the rear muffler. The over axle pipes house a redundant cat core along with a particulate filter that is empty on North American cars, allowing for an immediate transformation upon replacement of that component in particular. Our Competition Over Axle Pipes employ oval tubing for a full 3″ diameter and eliminate those corks in the flow to deliver the greatest flow into the rear muffler.

The GT4 RS’ rear muffler is carried over from the standard GT4, restricting the flowpath to the same diameter of the GT4 despite the increased engine output. Our Race Exhaust System utilizes a single flowpath that maintains a 3” diameter all the way through the tips. Our Resonated version with anti-drone tubes helps to reduce unwanted frequencies, while our Non-Resonated version is the ultimate lightweight solution for maximum sound from the GT4 RS.

 

CONSTRUCTION:  Each system 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:  Every component 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.

LIFETIME WARRANTY:  Enjoy your SOUL exhaust components with confidence on both the street and track as they are covered by our Lifetime Warranty! Our team will quickly work with you to resolve any issues or answer any questions that you may have.
