Description

DEVELOPMENT: Exhaust upgrades tailored to the GT4 platform will naturally focus on maximizing its motorsports character, and our Race Exhaust does so by redesigning the system after the headers to deliver optimal exhaust flow through the tips. The factory dual-exit/entry flanges connecting the Over Axle Pipes and PSE rear muffler limit tubing diameter to 2.25”, but the SOUL Race Exhaust System maintains 2.5” on either side and longer piping and a bespoke X-pipe produces a smoother and higher-pitched sound that was familiar to previous iterations of the GT4 and Boxster Spyder. Durable race resonators refine that aggressive exhaust note, and coupled with the drone canisters we developed for the GT4 RS, reduce drone to a comfortable level. A non-resonated version is available for drivers looking for maximum sound and weight savings.

POWER: Below are the unedited, straight from the Dyno Jet dyno results as conducted by Jotech Motorsports with before and after runs on a 718 GT4. Max power gains of 30.7 whp and 16.1 ft-lbs of torque come in quickly and hold until redline for a noticeable increase in driving performance. An ECU tune would further take advantage of the increased flow and unlock greater gains.

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 and four OEM Porsche gaskets are 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.
