Key features

• •Wide Application - Stainless Steel Headers compatible with 2004-2010 F150 XL XLT FX4 King Ranch Lariat 5.4L 330 V8. Please make sure this item fits your vehicle.
• •High Quality - The 2004 F150 XL exhaust manifold header is made of high-quality 16-gauge 304 stainless steel, and the head flange is laser cut from a high-quality 3/8-inch thick steel plate and flattened by a hydraulic press to achieve a precise, leak-free seal. Superior quality and durability enhance vehicle performance for value-conscious buyers.
• •Excellent Workmanship - All joints are golden color TIG brass style welded to prevent cracking and wear. The polished surface provides additional rust protection and is heavy enough to maintain header integrity yet flexible enough to seal each exhaust port. The short design allows for power gains from idle to the mid-rpm range.
• •Note: Due to increased emission standards in California, Colorado, New York, and Maine, our 2010 F150 header manifold kit is unavailable for sale in these states.
• •Half-Year Warranty - Customer satisfaction is SDonestep's top priority. To improve customer experience and quality of the 2004 F150 XL exhaust headers, if there is any damage during transportation or problems occurring during use, don't hesitate to contact us in time, and we will provide a 30-day return and a half-year warranty.
