---tab Description--- Unleash the true potential of your 1999.5-2003 Ford 7.3L Powerstroke with this high-performance Turbo Back Exhaust System. Crafted from durable 409 stainless steel, this complete system replaces the restrictive factory exhaust from the turbo outlet back. It is engineered to significantly reduce exhaust backpressure, resulting in faster turbo spool-up, improved engine performance, and a more aggressive, authentic diesel sound. Ideal for tuned trucks, heavy towing, and off-road use. Specification Exhaust Material T-409 Stainless Steel, it is magnetic. Inlet Diameter 4.0‘’ mandrel-bent construction Maximum flow efficiency, helping your diesel breathe easier Compatibility 1999.5-2003 Ford F-250 F-350 7.3L Powerstroke. Not compatible with Cab & Chassis models. Key Features Complete Turbo-Back Replacement: A full, direct-fit system that replaces the factory downpipe, catalytic converter, DPF, and intermediate pipes. Includes all necessary hangers and hardware for a straightforward installation. Reduced Exhaust Backpressure: Features a larger diameter piping design that allows exhaust gases to flow more freely, reducing the thermal and pressure load on the turbocharger and engine. Enhanced Engine Performance: By minimizing restrictions, this system promotes faster turbo response, easier torque release, and creates an optimal foundation for further performance tuning and modifications. Aggressive Diesel Soundwave: Eliminates restrictive factory mufflers and components, delivering a deeper, louder, and more commanding exhaust tone that highlights the character of your Powerstroke. Durable 409 Stainless Steel Construction: Offers superior corrosion resistance compared to the factory system, making it ideal for use in harsh environments like salted roads, farms, deserts, and coastal areas. Optimized for Demanding Use Cases: Perfectly suited for high-load applications such as off-roading, heavy towing, and track use, where reduced backpressure helps maintain performance and reliability under sustained stress. Tuner Required for Installation: Installing a 7.3L powerstroke delete pipe requires more than just swapping out hardware. When removing of the DPF, CAT, SCR, and/or DOC involves removing and eliminating emission related sensors. A DPF delete capable tuner is required to prevent any check engine light or diagnostic trouble codes from setting. ---tab Fitment--- 1999.5-2003 Ford F-250 F-350 7.3L Powerstroke Pickup Trucks Note: Not For Use In Vehicles Equipped With Catalytic Converter. ---tab Shipping & Returns--- Fast Shipping Policy Your order will be dispatched within 1-2 business days, and the package will arrive within your order's estimated date.
