• Fits all Porsche 991.2 Carrera vehicles
• Max power gains of approximately 12 whp and 20 ft-lbs of torque (as tested on Base model with ECU tune)
• Weighs 5.4 lbs / 2.4 kg less than factory exhaust components (9.9 lbs vs 15.3 lb)
• Designed and built in-house at our Willow Grove, PA facility
• All SOUL Performance Products exhaust components are backed by SOUL's Lifetime Warranty for both street and track use

DEVELOPMENT: SOUL sought out to maximize performance and boost response while minding clearance on daily driven cars. The optimized 3 into 1 merge collector design improves response over the poor factory design, while the runners ultimately increase exhaust velocity into the collector and turbo. Looking into the factory headers you will notice a support in the middle runner which is detrimental to a smooth flow path out of that exhaust port – all in all the design is very basic with lots of room for improvement. The factory turbo inlet measures around 1.54” ID and we sized our header outlet to 1.63” for a smooth flow path into the turbo. The internal volume of the header combined with the resulting design improvements pairs well with the efficiency map of the turbo giving you noticeably quicker boost response and more power throughout the RPM range. Pushing the gas pedal down commands faster feedback from the car and each gear has more usable power before a downshift.

The factory header utilizes a double wall design while our design is single wall yielding in a more pleasing, sharper edge to the exhaust and increased turbo sound. Exhaust volume and tone quality are delightfully increased without yielding drone or undesirable qualities. Expect more burbles and sharper pops between shifts and on deceleration.

POWER: Below are the real, unedited, straight from the Mustang dyno results as conducted by Apex Autoworks with before and after runs on a Base model Carrera already equipped with SOUL Sport Catalytic Converters and SOUL Performance Exhaust with COBB Accessport Stage 2 Map. This dyno chart is made of the average performing charts of 3 before and 6 after runs. Max power gains of 12 whp and 20 ft-lbs come in quickly and hold until redline for a noticeable increase in driving performance. A custom Pro Tune would further take advantage of the increased flow and unlock greater gains.

CONSTRUCTION: Each set is assembled in house in the USA out of laser cut flanges and mandrel bent, thick wall .065″” T304L stainless steel. Back purged TIG welding (with ARCAL™ Prime argon gas) ensures proper weld penetration and longevity. We fabricate these headers 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 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.

Upgrading the fuel system on an Evo X can be a lot of trouble if not thought out completely. It is very difficult to upgrade only one component without consideration for the others. The restrictive return line, the in-tank venturi jet pump system, the integrated fuel filter. All these, and more, create a complicated system to modify for high performance. If not thought out properly, issues will show up on the dyno, such as inconsistent fuel delivery, overly high fuel pressures, fuel starvation and more.
The Radium Complete Fuel Delivery System for the Evo X solves all these issues in one complete kit. Every details has been thought out and tested in real world conditions. The result is a bolt-on kit that performs as expected, capable of meeting the fueling needs of highly modified 4B11T engines.

WHATS INCLUDED
This comprehensive kit includes everything required to construct a high performance fuel delivery system for the EVO X. The title photo at the top of the this page shows the kit contents. The Radium fuel pump hanger, feed line kit, fuel rail, and pressure regulator completely replace the restrictive OEM fuel system with a setup capable of supporting well over 1,000hp. At the heart of the system is the Radium EVOX fuel pump hanger.

From the fuel pump hanger, the feed line kit passes fuel through a Radium in-line fuel filter using prefabricated -8AN PTFE hoses. The filter is mounted to the chassis under the car using a specially designed bracket that does not require any cutting or drilling for installation.

Kit comes standard with twin Walbro 450 pumps (Walbro F90000274 - 20-0642-02), a black Fuel Pressure Regulator (20-0623-00), and a stainless steel fuel filter (20-0246-03).

CAD Designed and 3D Printed ABS Plastic gauge pod for your Evo X.

This 52mm pod can be added to the left side of your OEM gauge surround.  It requires you to drill three small mounting holes to affix the pod to the stock plastics, as well as one larger hole to run the wiring through.

With these pods there is no more waiting for months to get a custom pod made only to have it crack.
