This part is intended as a direct replacement for compatible models. However, fitment can vary between model years and aftermarket parts—some vehicles may require minor adjustments. Professional installation is recommended to avoid modification issues.
The description does not specify any sensor bungs or included sensor hardware. Check the product photos or ask the seller directly if sensor ports or adapter fittings are required for your vehicle.
This is an aftermarket replacement up-pipe. While it is designed to route turbo exhaust, any change to exhaust components can potentially affect backpressure, turbo behavior and emissions. Check local emissions laws and consult a mechanic if you have concerns about compliance or performance changes.
Installation time varies by shop and vehicle condition. Because the part connects to the turbo and exhaust, a professional mechanic with standard exhaust/turbo tools is recommended. Rusted fasteners or restricted access can increase labor time.
For support or warranty claims (2-year manufacturer defect coverage), contact the seller or manufacturer directly. Provide your order information, vehicle details, photos of the part/defect and any installation notes when requesting assistance.
