Description

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:  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. Our Race Resonators are full stainless steel construction with a straight through perforated design to achieve maximum exhaust flow while cutting down on undesirable frequencies.

 

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.

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.

    I have some first hand experience to share with these new resonated OAPs when combined with the Valved Rear System. I’m very happy with this combination for my taste.

    I was after a little less cabin resonance and a more street friendly sound level. The Resonators do help control cabin boom/resonance, the impact is small yet noticeable back-to-back. I find they also help control overall tone and volume. If you are familiar with the tone of the valved rear system with standard OAPs, throaty, gurgles, and some crackles. These resonators certainly dampen some of that and yield a slightly higher pitch in overall tone, I feel the right amount. Sound is subjective, for my personal taste, I think without the resonators the outside sound is just at the line or slightly over for a street setup. With the resonators, I find it perfect, just rowdy enough but slightly refined. On a 1-10 rowdy scale, rear box only is a 4, rear + resonated OAPs is 6-7, and rear + OAPs is 8.
