Product Details 

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.

Soul's 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 their Resonated version tackles the drone under 2500 RPM using resonators and anti-drone tubes.

Features

  • 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 Soul's 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 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.

LIFETIME WARRANTY

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