The Pacemaker PP5321-51 is a full 3in cat-back kit for the Chevrolet Silverado 1500, fitted with rear resonators. The rear-resonator pairing is the headline: it tunes the note at the tailpipes to trim drone while keeping the cat-back run open behind the converter.
What does cat-back mean on the Silverado?
A cat-back system replaces everything from the catalytic converter rearward — the converter itself is left in place, and the pipework, silencing and tips behind it are swapped to the 3in run. On a big V8 ute like the Silverado 1500 that is the common upgrade path: it frees up the rear of the system without touching the emissions hardware at the front.
Why rear resonators on this variant?
This kit uses resonators at the rear rather than chambered mufflers. A resonator is a tuning device — it cancels a specific band of drone frequencies instead of absorbing volume broadly — so this layout keeps more of the V8's voice while cleaning up the cruise boom. It sits as the tuned-but-open option among the PP5321 builds.
Will it suit my Chevrolet Silverado 1500?
It is listed to fit the Chevrolet Silverado 1500. The supplier has not published a specific engine or year band for this listing, so confirm your exact model year and driveline with the workshop before ordering — we will check the listing against your truck rather than assume.
What does fitting involve at our Illawarra workshop?
Oak Flats Muffler Men supplies and fits this Pacemaker cat-back kit in-house across the Illawarra. As a full 3in kit it is a larger job than a single muffler swap; we confirm clearances along the run and at the rear resonators, then book the bay. The PP5321-51 RRP is published.
Stocked and fitted by Oak Flats Muffler Men, the Illawarra exhaust and 4x4 specialist in Oak Flats, NSW.
