DEVELOPMENT: The factory valved exhaust is rather free flowing with valves open, and Soul Performance wanted to craft an aggressive non-valved solution while mitigating drone through a longer exhaust tract. Soul Performance’s split bank 3″ crossover design offers maximum flow and V8 rumble while shedding approximately 20 lbs. Soul Performance has incorporated mounting brackets for the factory exhaust valves (designed to limit flow in four-cylinder mode) to prevent them from being damaged or throwing a check engine light due to removal.
Due to the close proximity of the exhaust to sensitive components and plastic, heat shields are a MUST. Soul Performance heard rumors of GM discussing potential issues related to heat from modifying the exhausts with dealers and have taken every precaution to implement heat shielding into every solution. Soul Performance 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 the Soul Performance 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. The Soul Performance 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.
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, reduced heat soak, and increased finish durability.
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.
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.
