FAQs
Will this fit my early-1997 OBS 7.3L?Yes—this kit covers 1994 through 1997.5 F-250/F-350 7.3L trucks (all cab/bed configurations).
What’s the difference vs. the 122004 kit?
Functionally similar sizing, but 162004 is T409 stainless while 122004 is aluminized. Stainless offers better long-term corrosion resistance.
Does it include the O2 bung?
If you only need a specific section with an O2 bung, Diamond Eye also sells the individual first/second sections (see 162002 and 162003 above). This 162004 listing is the full two-piece stainless kit.
Do I need tuning?
No tuning is required for installation of the downpipe alone. Always verify emissions and local regulations before modifying exhaust.
