Can I register a Silverado with the SSMKCH0036 fitted?

No. It deletes the catalytic converter, so it is not ADR 79/04 compliant for road registration in NSW and is for off-road use only.

Will it fit my 2500 HD?

It is listed to fit the Chevrolet Silverado 2500 HD 6.6L V8 turbo-diesel (2017–2019). Confirm your exact build with Oak Flats Muffler Men before ordering.

How loud is the no-muffler version?

With no muffler and no cat it is the most open of the family, so expect a louder, harder note than the muffled variants. We can't quote a noise figure.

This is the most open variant in the Silverado family: the MPI Automotive SSMKCH0036 is a 4in turbo-back that runs cat-delete and no muffler, listed to fit the Chevrolet Silverado 2500 HD 6.6L V8 turbo-diesel (2017–2019). With both the catalytic converter and the rear silencer left out, it is the least restricted, off-road-only configuration.

What does cat-delete and no muffler change?

A turbo-back replaces the exhaust from the turbo outlet rearward, so it is the full engine-back span rather than a tailpipe swap. This SSMKCH0036 takes the most open route of its family: it deletes the catalytic converter and runs without a muffler, so there is no chambered silencer or cat hardware in the path. That makes it the freest-flowing of the set, with the hardest, loudest note, but it removes the emissions control the truck left the factory with.

Is it road legal?

No — because the SSMKCH0036 deletes the catalytic converter on a road-relevant turbo-back system, it is not ADR 79/04 compliant for road registration in NSW and is sold for off-road use only. There is no softening this: removing the cat means the Silverado no longer carries the emissions equipment required for a registered vehicle on public roads here.

What suits the 4in bore on the 2500 HD?

The supplier lists this system at a 4in bore, which is sized for the big 6.6L turbo-diesel V8 in the 2500 HD rather than a small engine. Running 4in across a heavy American three-quarter-tonner keeps the pipe consistent with the truck's output, and with no muffler in the way the gas exits with the least obstruction the system allows.
