Valves open mode elicits an aggressive V8 rumble for an invigorating driving experience. Valves closed mode calms down the volume for more refined cruising with just enough presence to be appreciated. Built around premium high-flow catalysts, Soul Performance Products Sport Catalytic Converters offer significant increases in power and sound with no compromises or check engine lights.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003e+ \u003cspan\u003e \u003c\/span\u003e\u003c\/strong\u003eAll Soul Performance Products exhaust components are backed by our\u003cspan\u003e \u003c\/span\u003e\u003ca href=\"https:\/\/soulpp.com\/warranty\/\"\u003eLifetime Warranty\u003c\/a\u003e\u003cspan\u003e \u003c\/span\u003efor both street and track use\u003cbr\u003e\u003cb\u003e+\u003c\/b\u003e  Peak power gains of 17 whp and 20 ft-lbs of torque (as tested with factory valved exhaust)\u003cbr\u003e\u003cb\u003e+\u003c\/b\u003e  Added performance with NO check engine light\u003cbr\u003e\u003cstrong\u003e+  \u003c\/strong\u003eDesigned and built in-house at our Willow Grove, PA facility\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003cdiv class=\"woocommerce-tabs wc-tabs-wrapper\"\u003e\n\u003cdiv class=\"woocommerce-Tabs-panel woocommerce-Tabs-panel--description panel entry-content wc-tab\" id=\"tab-description\" role=\"tabpanel\" aria-labelledby=\"tab-title-description\"\u003e\n\u003ch4\u003e\u003cstrong\u003eDEVELOPMENT GOALS\u003c\/strong\u003e\u003c\/h4\u003e\n\u003cul\u003e\n\u003cli\u003eImprove upon the factory design to increase and refine the V8 tone.\u003c\/li\u003e\n\u003cli\u003eIncrease 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.\u003c\/li\u003e\n\u003cli\u003eHeighten 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.\u003c\/li\u003e\n\u003cli\u003eOffer the ability to notably reduce the sound level of the car outside to fly under the radar when necessary.\u003c\/li\u003e\n\u003cli\u003eAchieve an effective delta in sound between both modes for two usable, well engineered experiences – mild and wild.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003e\u003cstrong\u003eRESEARCH \u0026amp; DEVELOPMENT\u003c\/strong\u003e\u003c\/h4\u003e\n\u003cp\u003eWith 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.\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003cp\u003e\u003cimg decoding=\"async\" class=\"aligncenter size-large wp-image-13337\" src=\"https:\/\/soulpp.com\/wp-content\/uploads\/2021\/03\/Soul-Performance-Products-Chevy-Corvette-C8-Valved-Exhaust-System-Muffler-Diagram-1024x529.jpg\" alt=\"\" width=\"1024\" height=\"529\" srcset=\"https:\/\/soulpp.com\/wp-content\/uploads\/2021\/03\/Soul-Performance-Products-Chevy-Corvette-C8-Valved-Exhaust-System-Muffler-Diagram-1024x529.jpg 1024w, https:\/\/soulpp.com\/wp-content\/uploads\/2021\/03\/Soul-Performance-Products-Chevy-Corvette-C8-Valved-Exhaust-System-Muffler-Diagram-510x263.jpg 510w, https:\/\/soulpp.com\/wp-content\/uploads\/2021\/03\/Soul-Performance-Products-Chevy-Corvette-C8-Valved-Exhaust-System-Muffler-Diagram-64x33.jpg 64w, https:\/\/soulpp.com\/wp-content\/uploads\/2021\/03\/Soul-Performance-Products-Chevy-Corvette-C8-Valved-Exhaust-System-Muffler-Diagram-300x155.jpg 300w, https:\/\/soulpp.com\/wp-content\/uploads\/2021\/03\/Soul-Performance-Products-Chevy-Corvette-C8-Valved-Exhaust-System-Muffler-Diagram-768x397.jpg 768w, https:\/\/soulpp.com\/wp-content\/uploads\/2021\/03\/Soul-Performance-Products-Chevy-Corvette-C8-Valved-Exhaust-System-Muffler-Diagram.jpg 1280w\" sizes=\"(max-width: 1024px) 100vw, 1024px\"\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eAFM valve deletes\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003eare 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.\u003c\/p\u003e\n\u003cp\u003eDue 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.

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.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eCONSTRUCTION:\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003e 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.

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 \u003ca href=\"https:\/\/docs.google.com\/file\/d\/0B1DKgBxqE0JEME5wQ1pIc1N5dU0\/edit?pli=1\"\u003ehere\u003c\/a\u003e.\u003c\/p\u003e\n\u003cp\u003e\u003cimg decoding=\"async\" class=\"aligncenter size-full wp-image-13329\" src=\"https:\/\/soulpp.com\/wp-content\/uploads\/2021\/03\/Soul-Performance-Products-Chevy-Corvette-C8-Exhaust-System-PTP-Blanket-Detail-Site.jpg\" alt=\"\" width=\"1000\" height=\"623\" srcset=\"https:\/\/soulpp.com\/wp-content\/uploads\/2021\/03\/Soul-Performance-Products-Chevy-Corvette-C8-Exhaust-System-PTP-Blanket-Detail-Site.jpg 1000w, https:\/\/soulpp.com\/wp-content\/uploads\/2021\/03\/Soul-Performance-Products-Chevy-Corvette-C8-Exhaust-System-PTP-Blanket-Detail-Site-510x318.jpg 510w, https:\/\/soulpp.com\/wp-content\/uploads\/2021\/03\/Soul-Performance-Products-Chevy-Corvette-C8-Exhaust-System-PTP-Blanket-Detail-Site-64x40.jpg 64w, https:\/\/soulpp.com\/wp-content\/uploads\/2021\/03\/Soul-Performance-Products-Chevy-Corvette-C8-Exhaust-System-PTP-Blanket-Detail-Site-300x187.jpg 300w, https:\/\/soulpp.com\/wp-content\/uploads\/2021\/03\/Soul-Performance-Products-Chevy-Corvette-C8-Exhaust-System-PTP-Blanket-Detail-Site-768x478.jpg 768w\" sizes=\"(max-width: 1000px) 100vw, 1000px\"\u003e\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003cp\u003e\u003cb\u003eLIFETIME WARRANTY:  \u003c\/b\u003eEnjoy your SOUL exhaust components with confidence on both the street and track as they are covered for life!
