The MagnaFlow 15395 is a replacement tail-pipe section for 2003-2004 Dodge trucks with the 5.9L Cummins turbo diesel. It is made from stainless steel and mandrel bent, so the tube keeps a smooth, consistent path through each turn instead of the crimped transitions found on lower-cost pipe. That stainless construction is the main reason to pay more than for a basic aluminized replacement, since stainless resists the rust that typically attacks the rear of a diesel exhaust.
Stock rear exhaust sections on these trucks can rust through or crack at the joints over time, and a stainless MagnaFlow pipe is a longer-term fix for a 5.9 Cummins exhaust rebuild or cat-back refresh. MagnaFlow describes its tail-pipe design as direct-fit, using the factory exhaust break locations, which means you are not cutting and fabricating a universal pipe to fit. Fitment should still be confirmed against your specific truck, since sources give varying application details for this part number; check with the manufacturer before ordering. Search terms buyers use for this item include 03-04 Dodge Ram 5.9 Cummins stainless tail pipe, 2003 2004 Dodge diesel rear exhaust replacement, and mandrel bent stainless tailpipe.
The manufacturer describes the install as bolt-on and says it may require basic automotive knowledge, while recommending professional installation.
The manufacturer states that the direct-fit design uses the OEM exhaust break locations, so the pipe is intended to replace the factory section rather than be cut and welded to fit.
The manufacturer rates this as a bolt-on job that may require basic automotive knowledge, and it recommends professional installation. Plan to support the exhaust while the factory section is removed, and expect the old rusted hangers and clamps to be the hardest part of the job. Owners on user forums generally describe aftermarket exhaust pieces on this platform as straightforward when the factory breaks are reused. Confirm whether clamps and hangers ship with your specific order before you start.
