Porsche 718 GT4 / Spyder / GTS 4.0L SOUL Resonated Over Axle Pipes

DEVELOPMENT

We analyzed every aspect of the 718 GT4 exhaust system to determine sizing, positioning, and flow characteristics of our components. 3D scanning enabled us to create a perfect bend profile to produce beautiful large radius mandrel bends and a one piece full 2.25″ design. The end result is a highly optimized upgrade for your Porsche for both street and track use! Many enthusiasts modify multiple portions of the exhaust system in pursuit of power and tone which can increase the volume and cabin presence beyond their preference. The primary benefit of the resonated version of our over axle pipes is gaining the performance increase of removing OPF filters without increasing volume to a great degree, whereas the Competition Over Axle Pipes offer bolder tone and volume. If you’re running aftermarket headers or rear exhaust our straight through race resonators take the edge off the overall volume and reduce bass / resonance at low RPM for a more refined experience.

CONSTRUCTION

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

Optional 321 stainless steel embossed heat shielding dampens vibrations and encourages thermal stand-off with micro air pockets

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: 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.
