{"product_id":"cat-back-exhaust-system-with-2-5-tubes","title":"Cat-Back Exhaust System with 2.5\" Tubes","description":"The Stillen Cat-Back Exhaust System is engineered for the 2023+ Nissan Z 3.0T, aiming to deliver enhanced performance, flow, and sound. During development, engineers explored various configurations, ultimately choosing an X pipe design with a cross-sectional area of approximately 4 inches. This design merges the left and right exhaust banks, significantly improving sound quality over a true dual exhaust system while preventing flow restriction common in twin-turbo V6 engines.\n\nConstructed from durable 304 stainless steel, this cat-back system features precision tig welded components throughout. The 2.5\" tubes transition into the X pipe, which then leads to a pair of high-polished mufflers. These mufflers are assembled and welded in-house using proprietary machinery, resulting in a distinctive \"stack of dimes\" finish with a multi-color burn trail from the welding process.\n\nBuyers can customize the look of their exhaust with a choice of polished stainless steel, burnt stainless steel, or carbon fiber exhaust tips. The system also includes a Stillen branded cross-brace for support and aesthetic enhancement. This exhaust system is proudly made in America and comes with a limited lifetime warranty.","brand":"Stillen","offers":[{"title":"Default Title","offer_id":52869761728824,"sku":"50450","price":1133.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/688008792.webp?v=1787918103","url":"https:\/\/store.motormia.co\/products\/cat-back-exhaust-system-with-2-5-tubes","provider":"MOTORMIA","version":"1.0","type":"link"}
