Performance Exhaust for Custom Builds. The Magnaflow Custom Builder Pipe Series Turbo-Back Exhaust System is engineered to deliver powerful performance and sleek style for diesel enthusiasts. Built for 1999–2003 7.3L Powerstroke Ford F-350 Super Duty models, this turbo-back system improves flow and sound, offering dyno-proven gains in horsepower and torque. Its single passenger-side exit and polished chrome finish provide a clean, aggressive appearance with long-lasting shine.
Construction and Appearance. Made in the USA from 4-inch diameter stainless steel tubing, this exhaust features mandrel bends and CNC machining for precision airflow and reduced backpressure. The weight-optimized design maximizes performance without unnecessary bulk, while the polished chrome surface delivers a high-end, corrosion-resistant finish that stands up to extreme conditions.
Installation. This system is a direct replacement but requires cutting, welding, and fabrication for proper fitment—making professional installation strongly recommended. The clamp-on design supports a secure, leak-free connection, and the kit includes all necessary hangers, clamps, adapters, and mounting hardware for an adaptable setup that fits around your truck's underbody components.
Warranty. Backed by a limited lifetime warranty, this Magnaflow system offers long-term reliability and confidence against material or manufacturing defects, whether for daily driving, towing, or track use.
Application. This Magnaflow Custom Builder Pipe Series Turbo-Back Exhaust System fits 1999-2003 7.3L Powerstroke Ford F-350 Super Duty Models. It’s an ideal choice for custom diesel builds seeking superior sound, performance, and a premium chrome exhaust look.
