Porsche 718 GT4 RS / Spyder RS SOUL Sport Cat Over Axle Pipes

In order to provide the most effective and efficient performance solution for the GT4 RS, we opted not to offer a catted header replacement, but instead provide a modular Over Axle Pipe with a catalytic converter. As a standalone piece, our Sport Cat Over Axle Pipe with high-flow cats will deliver tangible sound and performance gains as it replaces the empty particulate filter on the factory units, and paired with our Competition Headers it is a remarkable increase while still retaining a monitored catalytic converter for emissions concerns.

To combat excess heat from the cat core, each of our Sport Cat Over Axle Pipes will include a heat solution as standard.

DETAILS:
+ Fits 718 GT4 RS / Spyder RS with factory or upgraded headers or rear exhaust
+ Weighs 6.3 lbs / 2.86 kg less than factory OAPs (18.7 lbs vs 25 lbs 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

DEVELOPMENT: In order to provide the most effective and efficient performance solution for the GT4 RS, we opted not to offer a catted header replacement, but instead provide a modular Over Axle Pipe with a catalytic converter.

CONSTRUCTION:  Each set 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:  Each set 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.
