FAQ
Will this fit my 2010 F-350 6.4L with a factory DPF?Yes—this is the second section, passenger-side tail pipe sized for 4" Diamond Eye DPF-back or turbo-back layouts on 2008–2010 6.4L Super Duty models. Confirm you are using 4" system components.
What’s the difference between 125041 and 165041?
125041 is aluminized steel (Performance Series). 165041 is stainless steel. Both share the same geometry and fitment; stainless offers maximum corrosion resistance.
Do I need additional hardware?
Most installs reuse existing clamps/hangers. We recommend adding a fresh 4" clamp such as Diamond Eye 454000 for a secure seal.
Is tuning required?
No tuning is required for replacing this section within a compliant exhaust configuration. Always follow local emissions laws.
