{"type":"firestarter.listing","listing":{"id":"lst_QsEONTgu","product_name":"Soul Performance Porsche 718 GT4 RS / Spyder RS SOUL Race Exhaust Package (Resonated)","category":"Exhaust","description":"Combining our Competition Over Axle Pipes with our Race Exhaust System eliminates the major bottlenecks in the GT4 RS exhaust flow and extracts the most sound and performance potential for the platform. Owing to the unique oval design of our Over Axle 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 (2022+)+  Weighs about 20 lbs less than factory exhaust components (39.15 lbs vs 59 lb factory)+  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.\nDescription\nDEVELOPMENT:  Borrowing its 4.0-liter flat-six from the 992 GT3 Cup, the 718 GT4 RS came delivered with serious motorsports pedigree. In order to satisfy worldwide regulations and meet production deadlines, certain components of the platform left performance and sound on the table. That’s what we’ve aimed to maximize.\n\n \nOur Race Exhaust Package tackles the biggest bottlen","images":["https://cdn.shopify.com/s/files/1/0024/4898/2060/files/SOUL-Performance-Products-718-GT4-RS-Race-Exhaust-Package-Resonated.webp?v=1772048793","https://cdn.shopify.com/s/files/1/0024/4898/2060/files/SOUL-Performance-Products-718-GT4-RS-Resonated-Race-Exhaust-2_9dcb8a28-69fd-422e-a6a4-e369a266c581.webp?v=1772048793","https://cdn.shopify.com/s/files/1/0024/4898/2060/files/SOUL-Performance-Products-718-GT4-RS-Resonated-Race-Exhaust-1_2023ac52-6089-4002-870a-cbc346c74675.webp?v=1772048793","https://cdn.shopify.com/s/files/1/0024/4898/2060/files/SOUL-Performance-Products-718-GT4-RS-Competition-Over-Axle-Pipes-1_7a8bc6a7-62ef-4ae3-b4ac-d3edbf0457cf.webp?v=1772048793","https://cdn.shopify.com/s/files/1/0024/4898/2060/files/SOUL-Performance-Products-718-GT4-RS-Competition-Over-Axle-Pipes-2_0251ddc1-993b-4078-a722-118762bd990f.webp?v=1772048793","https://cdn.shopify.com/s/files/1/0024/4898/2060/files/SOUL-Performance-Products-718-GT4-RS-Resonated-Race-Exhaust-Build_3d0733bc-433b-4481-8586-694ddc48357b.webp?v=1772048776","https://cdn.shopify.com/s/files/1/0024/4898/2060/files/Stock-vs.-Race-Exhaust-Package.webp?v=1772048776"],"price":5990,"currency":"USD","in_stock":true,"inventory_qty":59994,"dynamic_pricing":false,"listed_at":"2026-06-20T14:56:21.449Z"},"share_url":"https://firestarter.network/l/lst_QsEONTgu","purchase":{"summary":"Live product listing on the Firestarter agent commerce network.
