FAQs
Most owners start with a cold air intake and turbo-back exhaust system. This combination improves airflow, reduces EGTs, and increases turbo spool speed. For the 7.3L Ford Powerstroke engine, these upgrades provide the best performance gains relative to cost and pair well with tuning down the road.
Yes. The larger system moves heat faster and reduces load on the turbo. It also lowers exhaust pressure, which benefits older engines.
On a healthy 7.3 Powerstroke, a turbo-back or high-flow exhaust system typically adds about 10–20 horsepower and 20–40 lb-ft of torque.
Most of the gain comes from reduced exhaust backpressure and quicker turbo spool, especially when the exhaust is matched with a free-flowing intake.
It can create minor improvements by reducing intake restriction. Overall performance and fuel efficiency gains are small but throttle response becomes more consistent, especially on trucks used for towing.
Yes. Products are selected for 1999–2003 Ford models, including late-03 revisions. Fitment is matched to turbo orientation, pipe routing, and intake layout used on the final production year.
No. Delete and exhaust-removal components violate federal emissions law in the U.S. and are sold strictly for off-road or race use.
Dieselino does not sell custom tuning files or provide calibration services for the 7.3 Powerstroke. Our catalog for these trucks focuses on exhaust systems, exhaust tips, and cold air intake kits.
