SOUL Porsche 718 GT4 RS / Spyder RS Race Exhaust System

POR.718GT4RS

The factory rear muffler wasn’t much of a restriction on the standard 718 GT4, but reusing it for the GT4 RS has created a bottleneck for the GT3-derived engine. The tubing diameter remains the same, meaning that increased power is now forced through tubing that measures less than 2 ¼ inches. Repurposing that muffler helps meet sound restrictions and eases manufacturing processes, but doesn’t extract the most performance out of the GT4 RS.

Our Race Exhaust system measures a full 3 inches from the flanges to our tips, unleashing every bit of character from the 4.0-liter flat-six. The bespoke x-pipe creates a crisp motorsports tone, and our Resonated version tackles the drone under 2500 RPM using resonators and anti-drone tubes.

DETAILS:
+  Weighs 6.5 lbs / 2.9 kg less than factory exhaust components (27.5 lbs vs 34 lb factory)
+  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

Description

DEVELOPMENT: The factory rear muffler wasn’t much of a restriction on the standard 718 GT4, but reusing it for the GT4 RS has created a bottleneck for the GT3-derived engine. The tubing diameter remains the same, meaning that increased power is now forced through tubing that measures less than 2 ¼ inches. Repurposing that muffler helps meet sound restrictions and eases manufacturing processes, but doesn’t extract the most performance out of the GT4 RS.

Our Race Exhaust system measures a full 3 inches from the flanges to our tips, unleashing every bit of character from the 4.0-liter flat-six. The bespoke x-pipe creates a crisp motorsports tone, and our Resonated version tackles the drone under 2500 RPM using resonators and anti-drone tubes.

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.
