- Improve upon the factory design to increase and refine the V8 tone.
- Increase the presence and character of the exhaust note in the cabin while maintaining a reasonable level of resonance / drone while driving in both the valves closed and open modes through our signature drone fighting capabilities.
- Heighten aggressiveness with valves open while maintaining an overall sound level potential / quality that can still be reasonably driven on the street in combination with other complimentary aftermarket exhaust components – such as Sport Catalytic Converters or headers.
- Offer the ability to notably reduce the sound level of the car outside to fly under the radar when necessary.
- Achieve an effective delta in sound between both modes for two usable, well engineered experiences – mild and wild.
RESEARCH & DEVELOPMENT
With valves closed, the exhaust is routed through a bespoke SOUL chambered muffler we designed with an internal X-Pipe to meet our sound goals. This unique muffler was crafted to match our high standard of drone fighting mufflers that we are known for in the Porsche world. We tested a more traditional perforated core muffler design as well but the carefully engineered chambers of the final muffler result in a more aggressive sound on and off throttle with reduced undesirable tones. With valves open, exhaust flow is free to exit through 3″ piping for a thunderous roar. Secondary flow through the muffler and x-pipe reduces rasp and smooths the exhaust note for a higher pitched, more refined sound. The end result is two distinct and enjoyable sound modes – mild and wild.
AFM valve deletes are included for the factory exhaust valves (designed to limit flow in four-cylinder mode) in order to delete them without triggering a check engine light.
Due to the close proximity of the exhaust to sensitive components and plastic, heat shields are a MUST. We’ve partnered with PTP Turbo Blankets to produce a bespoke, form-fitting heat shielding solution. Far superior to no-name brand copies, PTP Lava Turbo Blankets are constructed with an outer layer made from pulverized volcanic lava rock (Rated 1800°F Direct Heat / 2500°F Radiant Heat) formed into fabric and woven into a tight mesh weave. These blankets are internally insulated with high temperature calcium magnesium silicate wool (Rated 1832°F Continuous / 2300°F Peak) overlaid with a high temperature stainless steel mesh for increased durability and improved thermal resistance. The Lava Blankets are designed to withstand the harshest of conditions.
CONSTRUCTION: Each component is made in-house by our fabrication team from mandrel bent .060″ wall T304L stainless steel tubing, laser cut brackets, and waterjet cut flanges. Welds are back purged for proper penetration and maximum durability. Our 4″ double wall stainless steel tips are available in a number of finishes and have depth adjustment for perfect fitment to meet your desired aesthetic.
HJS HD 200 CELL CATALYSTS: The highest quality catalytic converters available, known for their industry leading flow and durability. With their premium wash coat full of precious metals, they are efficient enough at catalyzing 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 a stout 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 – the same cats tested and proven on our McLaren and Porsche Turbo applications for big horsepower support.
FINISHES: SOUL tips are available in several styles and finishes. Natural finishes options include polishing, hand-brushing, and a matte Signature Satin. Black tips are ceramic coated with Jet-Hot for maximum bonding strength and increased finish durability. Looking for something unique? Contact us for custom logos and colors.
BOLT ON AND GO: Each exhaust component is built and tested in a thick gauge aluminum fixture (which prevents warping) to ensure perfect fitment. Every piece is rigorously quality-checked prior to shipping and then foam packed to ensure they arrive in perfect condition.
ABOUT PTP TURBO BLANKETS: Every PTP Turbo Blanket is hand-crafted in North America and quality is guaranteed. PTP Turbo Blankets are well known in the industry for their high standards for material selection, design, construction, and also for their ability to provide these high quality products at an affordable price. It is important to note that, as unfortunate as it is, there are many imitation turbo blankets out there – often made in China. These imitation turbo blankets are manufactured using much inferior materials for construction. Imitation turbo blankets can be ineffective or worse, they can be dangerous if flammable materials are used. PTP Turbo Blankets and wraps are the result of years of product research and development. The exact same materials that are used in their turbo blankets and wraps are currently being used in multiple military applications. Their materials are on the cutting edge of heat insulation technology – for more information see this full research paper here.
LIFETIME WARRANTY: Enjoy your SOUL exhaust components with confidence on both the street and track as they are covered for life! Our team will quickly work with you to resolve any issues or answer any questions that you may have. We cover our HJS catalytic converters with an unprecedented 3 year warranty while the components themselves are backed by our Lifetime Warranty.
IMPORTANT NOTE: You may experience a AFM check engine light codes after installing an aftermarket rear exhaust system on your C8. Recalibrating the AFM codes at your local dealer may be required. The procedure on average takes 15 minutes and is done through their computer system. If you have any questions or concerns please contact us.
