The Pacemaker PH2654 is a set of 1-7/8in headers listed to fit the Jeep Grand Cherokee SRT with the 6.4L Hemi V8. It's a left-and-right header pair that replaces the factory manifolds at the front of the exhaust.
What does this header set cover?
PH2654 is the L/R header pair for the Jeep Grand Cherokee SRT — the section that bolts to the 6.4L Hemi V8's heads and gathers the exhaust gas from each bank. The 1-7/8in figure is the primary tube size, the diameter of the individual runners off each cylinder before they merge into the collector. Supplied as a matched left and right, it covers the manifold replacement only; the cats and the rest of the system behind it are separate.
What are headers and what do they change?
Headers, or extractors, swap the cast factory manifolds for tubular primaries — one tube per cylinder feeding a collector. The general trade-off is a freer-flowing gas path against a more involved fit and a different note than stock. On a big V8 like the SRT's 6.4L Hemi, the manifolds are a common starting point for exhaust work. We hold no power or sound data for this set, so we describe it only as a 1-7/8in tubular header pair — a character change, not a measured one.
Will it suit my Jeep Grand Cherokee SRT?
It's listed to fit the Jeep Grand Cherokee SRT with the 6.4L Hemi V8. The supplier hasn't published a model-year range, so confirm your exact build with the workshop rather than assume coverage. Recommended retail is $1,848.77 for the pair.
What does fitting involve at our Illawarra workshop?
Oak Flats Muffler Men supplies and fits header sets like the PH2654 in-house across the Illawarra. Headers on the Grand Cherokee SRT are an engine-bay job, so we check the primary-tube clearances around the heads and ancillaries before final torque, and confirm how they suit the rest of your exhaust. Send your Jeep's details and we'll book it in.
Stocked and fitted by Oak Flats Muffler Men, the Illawarra exhaust and 4x4 specialist in Oak Flats, NSW.
