{"type":"firestarter.listing","listing":{"id":"lst_Pm8F3ITN","product_name":"Soul Performance Porsche 997.1 Carrera Cat Bypass Pipes","category":"Cat Bypass","description":"Upgrade your 997.1 Carrera with cat bypass pipes for the most aggressive exhaust note and more power.\nDETAILS:\n+  Fits all Porsche 997.1 Carreras (2005-2008) – note different part numbers between non-PSE and PSE exhaust equipped cars+  Weighs 6.25 lbs / 2.8 kg less than factory exhaust components (15 lbs vs 8.75 lbs)+  Designed and built in-house at our Willow Grove, PA facility+ All Soul Performance Products components are backed by a renowned Lifetime Warranty for both street and track use\nDescription\nDEVELOPMENT:  The factory 997.1 Carrera catalytic converters are quite restrictive and upgrading them is a common modification. We took a fresh look at the exhaust design to try and create the best possible solution. Side by side sound comparisons with our split bank design and an X-pipe design revealed that an x-pipe lowers yields a hollower exhaust tone and cuts out desirable deeper frequencies on the 997.1 – the difference is very noticeable. Separating the banks adds more volume and more character – a deeper and fuller flat six sound with a hint of rasp – almost air cooled inspired exhaust note. Throttle response and overall drivability is increased. Fall in love with your Carrera all over again with great gains in sound and power!\nCONSTRUCTION:  Each set is assembled out of 2.25″ OD, thick-wall .065″ T304L stainless steel and rigorously quality checked in-house. Smooth mandrel bends and thick flanges ensure product longevity. Each set of cat bypass pipes is tested in a fixture to ensure perfect fitment and then foam packed to ensure they arrive in perfect condition. New hardware is included for the header flanges.\nLIFETIME WARRANTY:  Enjoy your SOUL exhaust parts with confidence on both the street and track as they are covered by our Lifetime Warranty! Our team will quickly work with you to resolve any issues or answer any questions that you may have.\nCHECK ENGINE LIGHT?:  This product may trigger a check engine light due to the removal of factory catalytic conv","images":["https://cdn.shopify.com/s/files/1/0024/4898/2060/files/SOUL-997.1-Carrera-Sport-Catalytic-Converters-Product-1_1ceee844-d4c4-4f02-ab01-815fcaa78806.webp?v=1773943200","https://cdn.shopify.com/s/files/1/0024/4898/2060/files/SOUL-997.1-Carrera-Sport-Catalytic-Converters-Product-Detail_03edef5e-8fc4-4bd5-afe9-07665999bdc2.webp?v=1773943200","https://cdn.shopify.com/s/files/1/0024/4898/2060/files/SOUL-997.1-Carrera-Sport-Catalytic-Converters-Detail_88f5307c-f263-4ee3-bb93-4d21e2b20168.webp?v=1773943200","https://cdn.shopify.com/s/files/1/0024/4898/2060/files/SOUL-997.1-Carrera-Sport-Catalytic-Converters-Comparison-1.webp?v=1773943200"],"price":1555,"currency":"USD","in_stock":true,"inventory_qty":19998,"dynamic_pricing":false,"listed_at":"2026-06-20T14:56:21.200Z"},"share_url":"https://firestarter.network/l/lst_Pm8F3ITN","purchase":{"summary":"Live product listing on the Firestarter agent commerce network.
