These downpipes are available for different N55 engine configurations and years, with options for either a 3.5″ (Pneumatic Wastegate - PWG) or a 4.0″ (Electronic Wastegate - EWG) diameter. It is crucial to verify your specific vehicle's wastegate type to ensure correct fitment. The specific applications include a range of BMW models such as the 5 Series (F10, F11, F07), 6 Series (F12, F13, F06), 7 Series (F01, F02), and X5/X6 (E70, E71, F15, F16) across various model years. To guarantee proper fitment, customers are advised to send a picture of their wastegate from the engine bay for verification. Key features include the direct bolt-on application for straightforward installation, TIG-welded 304-grade stainless steel construction for durability, and smooth radius bends for enhanced flow. The product comes with a VRSF Lifetime Warranty.
