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.
+ Fits all Porsche 991.2 Carrera base / S vehicles without 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!
The APR GTS K04.3 Turbocharger System converts your 991.2 911 3.0T to the larger factory GTS turbochargers and includes our Stage 3 ECU Upgrade making the conversion plug-and-play! Up-to 615 HP and 549 FT-LBS of torque is available with no other modifications. Adding upgraded intercoolers bumps power up to 648 HP. This is a substantial increase in power and torque. Expect up to an additional +263 HP and +266 FT-LBS over stock on the base engine, and +244 HP and +223 FT-LBS on the S engine! This conversion system, sometimes dubbed an x51 package by Porsche, includes all genuine parts. It includes two new and genuine Borg Warner K04.3 Turbochargers, new gaskets, and o-rings. Simply remove and replace the factory components with our new components. No other hardware upgrades are required as the 3.0T mostly shares the same components, except for the turbochargers, from the base model to the GTS model. This system works with your factory engine hardware, factory fueling, and factory emissions components. It even works with upgraded engine and exhaust components and picks up even more power with upgraded intercoolers! This is all made possible by the included world-class APR Stage 3 ECU Upgrade which is programmed to your factory ECU at no additional charge!
