A cat-delete turbo-back that keeps a muffler is what defines the MPI Automotive SSMKCH0026 — the more tempered of the full-length stripped builds. This stepped 4in-to-5in section is listed to fit the Chevrolet Silverado 2500 HD T1 6.6L turbo-diesel V8 (2020–2025).

Is it road legal?

No. The SSMKCH0026 deletes the catalytic converter on a road-relevant turbo-back exhaust, so it is not ADR 79/04 compliant for road registration in NSW and is intended for off-road use only. Retaining the muffler tempers the note, but the cat delete makes this an off-road part regardless — there's no softening it.

Why a muffler on a full turbo-back delete?

Unlike the fully-stripped version, the SSMKCH0026 keeps a muffler in the stepped 4in-into-5in run. That holds the note down while the cat is removed, so it's the quieter of the no-cat turbo-back options — for an off-road Silverado owner who wants the big-bore flow without the harshest tone. The bore figures here are the system's own spec, sized for the diesel V8.

Will it suit my Silverado 2500 HD?

It's listed to fit the 2020–2025 Chevrolet Silverado 2500 HD T1 6.6L turbo-diesel V8. Send your exact build to the workshop so we can confirm the listing against your truck before ordering this off-road section.

What's involved in fitting it in the Illawarra?

Oak Flats Muffler Men supplies and fits this MPI Automotive turbo-back in-house across the Illawarra. As a cat-delete off-road build, we'll confirm intended use, check hanger points on the stepped run and the listed Silverado fitment, then book the bay. The RRP is $6,713.23.

Common questions

Can I register a Silverado with the SSMKCH0026?
No. With the catalytic converter deleted it is not ADR 79/04 compliant for road registration in NSW and is for off-road use only.
Is it quieter than the no-cat, no-muffler turbo-back?
Yes — this variant keeps a muffler, so it's more tempered than the fully-stripped version. We don't publish decibel figures.
Will it fit my 2500 HD?
It's listed to fit the 2020–2025 Silverado 2500 HD T1 6.6L turbo-diesel V8. Confirm your exact build with the workshop first.
