Under normal operation, most vehicles’ exhaust systems heat up to around 400–500°F (200–260°C), while during hard acceleration or towing, temperatures can rise to 800–1,000°F (425–540°C). The hottest area is typically the exhaust manifold or header, which may exceed 1,200°F (650°C) before gases cool down along the system.\u003c\/p\u003e\u003c\/li\u003e\n            \u003cli\u003e\u003cp\u003eAs exhaust gases travel through the catalytic converter, muffler, and tailpipe, the temperature gradually drops to around 200–400°F (93–204°C) near the outlet. Factors such as air-fuel ratio, material type, and pipe design also affect heat levels. Because of these extreme temperatures, using heat-resistant materials, wraps, or shields is essential to protect nearby components and ensure long-term performance.\u003c\/p\u003e\u003c\/li\u003e\n            \u003c\/ul\u003e","brand":"Dynofitauto","offers":[{"title":"Default Title","offer_id":64553565716849,"sku":"DN-50P1101","price":289.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0914\/0420\/6449\/files\/DN-50P1101.jpg?v=1789011898","url":"https:\/\/www.dynofitauto.com\/products\/3-5-exhaust-pipe-kit-t-304-stainless-steel-mandrel-bend-8-piece-dynofit","provider":"Dynofit Auto","version":"1.0","type":"link"}
