The MPI Automotive SSMKCH0024 is a 4in turbo-back exhaust listed to fit the Chevrolet Silverado 2500 HD (T1) 6.6L V8 from 2020 to 2025. It keeps the catalytic converter and runs a muffler, so it is the full engine-back upgrade for the big diesel rather than a tailpipe change.
What does this turbo-back cover?
A turbo-back replaces the exhaust from the turbo outlet all the way back, the longest span short of touching the manifold, and the section where a heavy-duty diesel like the 6.6L Silverado tends to free up. On this 2020–2025 2500 HD it is the engine-back system, built around the truck's size and the 4in bore.
Why it keeps the cat and runs a muffler
This build retains the catalytic converter and finishes through a muffler, so it keeps the factory emissions hardware in place and keeps the note civil rather than raucous — the sensible combination for a daily-driven tow vehicle. Keeping the cat is the part that matters for road compliance on a diesel. Confirm the exact build and any state requirements with the workshop before fitting.
Why the 4in bore on the 2500 HD?
At 4in this is sized for the 6.6L V8's output and the size of the truck, keeping restriction down across a long run of pipework. The bore is matched to the engine; the workshop confirms it suits your build and routes correctly under the 2500 HD before fitting.
