{"type":"firestarter.listing","listing":{"id":"lst_-eE0-GFt","product_name":"Soul Performance Porsche 718 GT4 RS / Spyder RS SOUL Street Package (Resonated)","category":"Exhaust","description":"Combining our free-flowing Over Axle Pipes with our Valved Exhaust System eliminates the major bottlenecks in the GT4 RS exhaust flow and extracts the most sound and performance potential for the platform, but still allows for comfortable cruising with the valves closed. Owing to the unique oval design of our Over Axle Pipes and the Valved Exhaust’s x-pipes, this system runs a full 3 inches all the way through, ensuring that the 4.0-liter flat-six realizes its motorsports pedigree in every way.\nExhaust Tip Selection: For those looking to maintain the factory appearance, this system can be used with OEM exhaust tips. However, please note that the OEM tips feature a much smaller diameter inlet, requiring the system to be necked down, which introduces a restriction and reduces overall performance. To extract the most from your GT4 RS, we strongly recommend selecting our high-performance exhaust tips, designed to complement the full 3-inch system without any compromises.\nDETAILS:\n+  Fits Porsche 718 GT4 RS / Spyder RS with factory or upgraded headers+  No check engine light on North American cars, ECU tuning required for European cars+  All SOUL Performance Products exhaust components are backed by the industry’s first and finest Lifetime Warranty for both street and track use+  Designed and built in-house at our Willow Grove, PA facility\nNOTE: Because of the increased output of the GT3-derived engine in 718 RS models, and the additional heat generated as a result, we strongly recommend applying a thermal management solution to Over Axle Pipe products to protect nearby components and body parts. We offer an efficient and effective wrapping solution in-house.\nDescription\nDEVELOPMENT: Acting on our initial goal of maximizing sound and performance potential from a cat-back exhaust system delivered us immediate results with our Over Axle Pipes and rear exhaust system. But for those who’d like to dial it back when appropriate, a Valved Exhaust System would meet their sound g","images":["https://cdn.shopify.com/s/files/1/0024/4898/2060/files/SOUL-Performance-Products-718-GT4-RS-Valved-Exhaust-Package-Resonated.webp?v=1772059705","https://cdn.shopify.com/s/files/1/0024/4898/2060/files/SOUL-Performance-Products-718-GT4-RS-Valved-Exhaust-8_69665f3a-e4ef-4ce0-bdb0-b31872ebd55f.webp?v=1772059705","https://cdn.shopify.com/s/files/1/0024/4898/2060/files/SOUL-Performance-Products-718-GT4-RS-Valved-Exhaust-2-1_a4f52901-6f2e-4453-8caf-c747c6c12a5d.webp?v=1772059705","https://cdn.shopify.com/s/files/1/0024/4898/2060/files/SOUL-Performance-Products-718-GT4-RS-Competition-Over-Axle-Pipes-1_aa22400f-f1ce-443f-abe6-fef5805145f2.webp?v=1772059705","https://cdn.shopify.com/s/files/1/0024/4898/2060/files/SOUL-Performance-Products-718-GT4-RS-Resonated-Over-Axle-Pipes-1.webp?v=1772059705","https://cdn.shopify.com/s/files/1/0024/4898/2060/files/SOUL-Performance-Products-718-GT4-RS-Resonated-Over-Axle-Pipes-3_d501266e-09b8-4678-89db-d2189fd6a726.webp?v=1772059705","https://cdn.shopify.com/s/files/1/0024/4898/2060/files/SOUL-Performance-Products-718-GT4-RS-Valved-Exhaust_411de70e-bc96-461d-9da6-1dbda4bf7287.webp?v=1772059705","https://cdn.shopify.com/s/files/1/0024/4898/2060/files/SOUL-Performance-Products-718-GT4-RS-Valved-Exhaust-4-1_05f8f3cf-d9bf-4804-9543-c3177b0ef71c.webp?v=1772059705","https://cdn.shopify.com/s/files/1/0024/4898/2060/files/SOUL-Performance-Products-718-GT4-RS-Valved-Exhaust-6_5a969a58-9e39-4e53-afe8-61873b0a3714.webp?v=1772059705","https://cdn.shopify.com/s/files/1/0024/4898/2060/files/SOUL-Performance-Products-Porsche-718-GT4-RS-Valved-Exhaust-OEM-Tips.webp?v=1772059705","https://cdn.shopify.com/s/files/1/0024/4898/2060/files/SOUL-Performance-Products-718-GT4-RS-Valved-Exhaust-Package-Comp.webp?v=1772059705","https://cdn.shopify.com/s/files/1/0024/4898/2060/files/SOUL-Performance-Products-718-GT4-RS-Valved-Exhaust-7_89e7fabd-cfff-4f86-8136-7101c3f68c2e.webp?v=1772059705","https://cdn.shopify.com/s/files/1/0024/4898/2060/files/SOUL-Performance-Products-718-GT4-RS-Valved-Exhaust-Build_3e78d595-0bfb-4cd2-9571-d1b9e4d67024.webp?v=1772059705","https://cdn.shopify.com/s/files/1/0024/4898/2060/files/JMW_2028-scaled.webp?v=1772059705","https://cdn.shopify.com/s/files/1/0024/4898/2060/files/SOUL-Performance-Products-718-GT4-RS-Valved-Exhaust-Installed_a7aabafa-24d8-4bc8-9737-6ae9a2fa2e78.webp?v=1772059705","https://cdn.shopify.com/s/files/1/0024/4898/2060/files/Stock-vs.-Competition-OAPs-Valved-Exhaust-System.webp?v=1772059666"],"price":8890,"currency":"USD","in_stock":true,"inventory_qty":79992,"dynamic_pricing":false,"listed_at":"2026-06-20T14:56:21.431Z"},"share_url":"https://firestarter.network/l/lst_-eE0-GFt","purchase":{"summary":"Live product listing on the Firestarter agent commerce network.
