YouTuber StreetSpeed717 was one of the first C8 Corvette owners with a custom built Cat Back Exhaust with Sport Cats from a local shop in his area Soul Performance.
It is one of the best sounding, looking, and lighter Exhaust options vs. the stock exhaust and cats.
Per Soul Performance website check out more information on their Cat Back Exhaust system and their Sport Cats for the C8 Corvette and watch some of the videos below to hear it rip.
Chevrolet C8 Corvette Performance Rear Exhaust System
Unleash a more aggressive roar from your C8 Corvette with the SOUL non-valved 3″ performance rear exhaust while reducing heat soak with a high grade heat blanket solution.
+ All Soul Performance Products exhaust components are backed by our Lifetime Warranty for both street and track use
+ Weighs approximately 20 lbs less than factory valved rear exhaust
+ Built in valve motor brackets safely support the factory valve motors to prevent damage or check engine lights
+ Designed and built in-house at our Willow Grove, PA facility
DEVELOPMENT: The factory valved exhaust is rather free flowing with valves open, and we wanted to craft an aggressive non-valved solution while mitigating drone through a longer exhaust tract. Our split bank 3″ crossover design offers maximum flow and V8 rumble while shedding approximately 20 lbs. We’ve 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. We’ve 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. 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.
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.
Chevrolet C8 Corvette Sport Catalytic Converters
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 V8 rumble, throttle response, and power for your C8 Corvette.
+ All Soul Performance Products exhaust components are backed by a renowned Lifetime Warranty for both street and track use
+ Added performance with NO check engine light
+ Peak power gains of 17 whp and 20 ft-lbs of torque (as tested with factory valved exhaust)
+ Weighs 9.6 lbs / 4.3 kg less than factory exhaust components (16 lbs vs 25.6 lb)
+ Designed and built in-house at our Willow Grove, PA facility
CONSTRUCTION: Each set is assembled in house in the USA out of mandrel bent, thick wall .065″” T304L stainless steel. Back purged TIG welding ensures proper weld penetration and longevity. We fabricate these cats 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. Due to the close proximity of the catalytic converters to sensitive components, heat shields are a MUST with the C8! We’ve partnered with PTP Turbo Blankets to produce a bespoke, form-fitting heat shielding solution.

UPDATE! Soul Performance Full Cat Back Exhaust and Sports Cats for the C8 Corvette
Here is another Performance Shop Team Nur installing the new Soul Performance full C8 Exhaust.
With the Soul Performance Sport Cats for the C8 it improved the horsepower from 450 baseline to 471 with the stock exhaust still on. C8 picked up 20 wheel horsepower and 20+ more torque.
With the Soul Performance Sport Cats and the Soul Performance Cat back straight pipe it sounds insane and without tuning it gained about 5 more horsepower and torque as well. Overall it’s a win and sounds insane!
