Why CPP Diesel
Fast shipping, diesel-focused tech help, and curated 7.3L Power Stroke exhaust options that fit and perform.
Will this fit my 1999–2003 F-250/F-350 7.3L?
Yes — it’s designed for 7.3L Super Duty trucks from 1999–2003. See the fitment list above. If your truck has a catalytic converter, this pipe is not for you.
Do I need tuning after installing this down pipe?
No tuning is required just for the down pipe. Many customers pair it with a full MBRP turbo-back system for maximum gains.
What’s the difference between Armor Lite and Armor Plus?
Armor Lite is aluminized steel (great value). Armor Plus uses T409 stainless for increased corrosion resistance. See the stainless FS9401 alternative above.
Is hardware included?
Reuses factory-style connections; existing clamps/hardware are typically reused. Inspect and replace worn clamps as needed.
