{"product_id":"cat-back-exhaust-system-stainless-steel-4","title":"Cat-Back Exhaust System Stainless Steel","description":"The Maptun Cat-back exhaust system is engineered for the Saab 9-3 II Aero models equipped with a 61-liter fuel tank. This performance exhaust system features a tailpipe with dimensions of 85x150 mm and is specifically designed for models that have a cut-out in the spoiler or if the spoiler has been modified.\n\nConstructed with SS Quality, the primary material for this exhaust system is stainless steel (AISI 304\/EN 1.4307\/SS2333). To enhance toughness and reduce the risk of cracks, the inner components are made from chrome steel. While flanges and some mounting parts are not stainless, the main body benefits from the corrosion resistance and longevity of high-grade stainless steel. The material's properties, including its austenitic nature, alloyed chromium and nickel content, and low carbon for weldability, are detailed. It's noted that stainless steel can discolor at high temperatures, which is normal and does not impact durability. Surface rust spots, often caused by external contamination like road spray, can also occur but are typically easy to polish off and do not significantly affect the product's lifespan.\n\nThe expected lifespan for products in SS Quality is substantial, ranging from 10 to 20 years, indicating a long-term investment in your vehicle's performance and appearance.","brand":"Maptun","offers":[{"title":"Default Title","offer_id":52865788543288,"sku":"04-13041","price":545.67,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/687440774.jpg?v=1787902947","url":"https:\/\/store.motormia.co\/products\/cat-back-exhaust-system-stainless-steel-4","provider":"MOTORMIA","version":"1.0","type":"link"}
