Silverado 2500 HD LTZ, 6.6L TD V8, 2020-2025, 4in Without Muffler, DPF Replacement Section (SKU: SSMBM834WOM).
Category: Mufflers and resonators


A DPF replacement section rather than a full system, the MPI Automotive SSMBM834WOM is a 4in part with no muffler, listed to fit the Chevrolet Silverado 2500 HD LTZ 6.6L turbo-diesel V8 (2020–2025). It swaps a single section of the run rather than the whole exhaust.
This is a replacement piece for the area where the diesel particulate filter sits, supplied at 4in and without a muffler. Rather than a complete cat-back or turbo-back, it's one section of the system, so it changes only that portion of the run on the Silverado's 6.6L turbo-diesel V8. The muffler-free build keeps it open through that section, and because it's a single part it's the most economical way to address just this area rather than re-pipe the whole truck.
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 exact interface to your existing pipework 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 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, detailed compliance for your configuration is something we'll talk through with you. The RRP is $464.20.
