Dodge Diesel Trucks Performance Exhaust - aFe - DPF Back, Large Bore-HD, 4" 409 Stainless Steel, Black Tip - Polished - `07-`12. This aFe Large Bore-HD DPF-back exhaust is built for Dodge diesel enthusiasts seeking improved flow and durable construction in a direct-fit system.

This DPF-back system is constructed from 4" mandrel-bent 409 stainless steel and is 100% hand MIG-welded for long-term strength. The design reduces backpressure and helps lower exhaust gas temperatures thanks to its intercooled 5" polished slash-cut tip with venting. It installs using factory mounting locations and OE-style band clamps for a straightforward, no-fuss installation while retaining a factory-like fit. The result is a robust upgrade that targets better flow characteristics and a more aggressive, diesel-friendly sound without unnecessary modifications.
