Porsche 718 GT4 RS / Spyder RS SOUL Race Exhaust System

Price range: $2,895.00 through $3,835.00

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 2,500 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

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 2,500 RPM using non-restrictive resonators and anti-drone tubes.

EXHAUST TIP SELECTION

For those looking to maintain the factory appearance, this system can be used with OEM exhaust tips. However, the OEM tips feature a much smaller diameter inlet, requiring the system to be necked down, which introduces a restriction and reduces overall performance. To extract the most from your GT4 RS, we strongly recommend selecting our high-performance exhaust tips, designed to complement the full 3-inch system without any compromises. Choose between double wall tips or our Weissach style stainless steel tips.

HAND-CRAFTED CONSTRUCTION

Mandrel bent, durable .065″” T304L stainless steel tubing

Back purged TIG welding (with ARCAL™ Prime argon gas) ensures proper weld penetration for exceptional strength and longevity

Water jet cut brackets are made to ISO 9001:2015 standards with ultra-tight tolerances of +/- 0.003 inches for extreme precision

Fabricated using thick-gauge aluminum fixtures that act as a heat sink during the welding process to prevent any warpage

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.
