UNLOCK HIDDEN PERFORMANCE
Modern Porsches must meet ever-growing sound and stringent European emissions regulations that have made their way stateside. The GTS pushes over 500 hp through a downpipe that is possibly the most restrictive exhaust piece we’ve ever seen on a performance vehicle.
The eTurbo turbocharger in the T-Hybrid system offers an advantage over a traditional turbo design. To guarantee sustained performance with an ideal air-fuel mixture ratio, Porsche uses a very large exhaust diameter. Without assistance from the eTurbo, these larger flow cross-sections in the exhaust components would result in significant turbo lag. The electric motor drastically shortens the time required for the turbo to spool up, meaning that the full boost pressure is consistently available within a very short time. This ensures that the engine maintains the ideal air-fuel mixture ratio and still builds up torque quickly – almost immediately. In spite of this potential for high exhaust flow, gases are choked by a massive 8” GPF filter and restrictive catalytic converter.
By eliminating the GPF filter and upgrading to an optimized catalytic converter, the massive increase in efficiency from the SOUL Sport Cat Downpipe results in better response under all conditions and a noticeably harder pull throughout the power curve . We have seen gains of over 50 whp and 40 ft-lbs of torque with our Performance Exhaust System and factory software (shown below) – the majority of those gains are a result of the efficiency boost in the sport cat section.
FACTORY INTEGRATION
We went to great lengths to replicate the factory GPF pressure differentials and O2 sensor behavior, helping minimize the potential for a CEL on otherwise untuned vehicles.
SATISFYING SOUND
Upgrading the downpipe section offers a more transformational sound experience than replacing the factory valved exhaust system. With this downpipe upgrade, overall exhaust volume is increased subtly with valves closed and noticeable so with valves open. For those who love turbo sound – expect much greater levels of boost volume!
*Drone Not Found* Undesirable cabin presence is kept to an absolute minimum across all modes with valves open and closed for comfortable cruising conditions.
*Neighbor Friendly* Cold starts are only mildly affected as the valves close immediately upon startup.
HAND-CRAFTED CONSTRUCTION
Mandrel bent, durable .065″ T304L stainless steel tubing
Premium SOUL designed catalytic converter with custom specced precious metal catalyst coating and triple metal matrix core
Engineered provisions for GPF metering
Using next-generation metal 3D printing technology, we engineered a 316L inlet to deliver optimum flow into the catalytic converter
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
Every component undergoes rigorous quality control and is fixture-tested to guarantee precise fitment. After passing QC, each downpipe is foam-packed to ensure it arrives in perfect condition. A new turbo gasket is included.
