• 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.

Upgrade from the restrictive factory catalysts to Soul Performance Products Sport Catalytic Converters, built around premium HJS HD 200 cell catalysts which offer significant increases in power and sound with no compromises or check engine lights. Enjoy a respectable gain in turbo sound and throttle response for your Carrera.

DETAILS:

+ Fits all Porsche 991.2 Carrera base / S vehicles with Porsche Sport Exhaust / PSE (2017+)
+  Designed and built in-house at our Willow Grove, PA facility
+  Added performance without a check engine light
+  Retains use of factory turbo heat shields
+  All Soul Performance Products exhaust components are backed by our Lifetime Warranty for both street and track use

DEVELOPMENT AND TESTING:  We set out to increase power and sound without throwing a check engine light. Using HJS HD 200 cell catalysts allows us to do just that. We designed our Sport Catalytic Converters to have the best possible exhaust path with valves open in pursuit of maximum exhaust flow – no compromises.

POWER:  We approached AWE Tuning about testing our development car at their facility for third party dyno results. We experienced gains of 12 whp and 13 ft-lbs of torque at 4,700 RPM as tested on a 2017 Carrera 4S with no other mods. Peak power was up by 14 whp and 15 ft-lbs. Much greater gains can be expected from the freer flowing exhaust components when paired with a tune.

CONSTRUCTION:  Each set is assembled in house out of mandrel bent, thick wall .065″” T304L stainless steel. Back purged TIG welding ensures proper weld penetration and longevity. Each set is tested in a fixture to guarantee fitment and then foam packed to ensure they arrive in perfect condition.

HJS CATALYSTS:  The highest quality catalytic converters available, known for their industry leading flow and durability. They are efficient enough to meet strict EURO 4 emission standards while still allowing for an increase in flow – all without a check engine light. The HD design uses premium triple foil winding for maximum strength. The brazing stripe is an extra feature in the interest of durability – it prevents the core from moving or experiencing any damage from sustained high horsepower abuse. We use a large and appropriately sized catalyst to allow for maximum gains – no compromises here!

Product Notes

These turbos are based off of remanufactured factory turbos.

THESE PARTS ARE LEGAL FOR USE ONLY IN COMPETITION RACING VEHICLES AS DEFINED UNDER CALIFORNIA LAW, AND ARE NOT LEGAL FOR USE IN ANY OTHER MOTOR VEHICLE.

Specifications:
Flow: ~50 lbs/min
Turbine: 49mmx49mm
Compressor: 49mm
Similar to the Tial M800 sizing but in the M660 (Carrrera/S) housing.

Compatible with Carrera/T/S/GTS 991.2 Porsche 911.


These are the largest free flowing upgrade turbos available for these cars, with nearly stock-like spool. Our turbos are sized to be aerodynamically capable of 800whp.

Dyno Run 1 – Stock 991.2 Carrera on 93 pump gas made 341whp & 331wtq

Dyno Run 2 – 93 pump gas, FBO, & stock Tune Only Made 353whp & 339wtq

Dyno Run 3 – 93 pump gas, FBO with a tune stock turbos made 457whp & 479wtq

Dyno Run 4 – 93 pump gas, Pure Upgrade Turbos, FBO, and Tune made 536whp & 485wtq

Pushing the OE PDK trans past 500tq is really pushing the PDK.
Also they ran out of MAP sensor throughout the tuning process. Once there is an upgraded MAP option and PDK option they can really push these turbos more.

You will receive a refund for your cores of $2600 for a functioning K03 Turbo (from a Carrera/T/S) or $3200 for a functioning K04 Turbo (from a GTS). This will make the cost of these turbos $3849 if you return K03 turbos or $3249 if you return K04 turbos.

These turbos by Tial are a bolt-on upgrade replacement for the factory turbos. Capable of 650-770whp. These are an upgrade for all of the 991.2 3.0L turbo motors including the Carrera, Carrera T, Carrera S, and Carrera GTS.

These are brand new turbochargers and do no require your cores to be sent in. 

You will receive a refund for your cores of $2600 for a functioning K03 Turbo (from a Carrera/T/S) or $3200 for a functioning K04 Turbo (from a GTS).
