Silverado 2500 HD LTZ, 6.6L TD V8, 2020-2025, 4in Muffler, DPF Replacement Section (SSMBM834MF) Fits
Category: Mufflers and resonators


The muffler-equipped DPF replacement section, the MPI Automotive SSMBM834MF is a 4in part that includes a muffler, listed to fit the Chevrolet Silverado 2500 HD LTZ 6.6L turbo-diesel V8 (2020–2025). It replaces a single section of the run rather than the whole system.
Where a section can be supplied muffler-free, this SSMBM834MF includes a muffler in the 4in DPF replacement area. That keeps the note more subdued through that part of the run, so it suits an owner who wants this section addressed without opening the exhaust up. It's a single-section part for the Silverado's 6.6L turbo-diesel V8, not a complete exhaust, so it swaps just the relevant portion of the system while keeping the rest of your pipework in place.
It's listed to fit the 2020–2025 Chevrolet Silverado 2500 HD LTZ with the 6.6L turbo-diesel V8. Because it's a section rather than a full system, the interface to your existing run is what matters most — send your build to the workshop so we can confirm it lines up before ordering, particularly where it joins the rest of your exhaust.
Oak Flats Muffler Men supplies and fits this MPI Automotive section in-house across the Illawarra. We confirm how the 4in muffler section mates to your existing run, check the listed Silverado fitment, and book the bay. As this is one section of the system rather than a complete exhaust, we'll talk through compliance for your specific configuration. The RRP is $713.90.
