The Pacemaker PH5302_L_R is a left-and-right pair of 1-5/8in Tri-Y headers for the Chevrolet 283–400 small-block V8, listed to suit the Holden HK/HT/HG. The published RRP is $1159.44 AUD.

What does this part cover?

This is a bare header pair — left and right 1-5/8in Tri-Y headers — built for the Chevrolet 283–400 small-block V8 and listed to suit Holden HK/HT/HG cars running that engine. The 1-5/8in figure is the primary tube size from the listing. It replaces the cast manifolds; it isn't a full exhaust, so the system behind it is separate.

What is a Tri-Y header and what does it change?

A Tri-Y header pairs the primary tubes before the final collector rather than running straight four-into-one. On a small-block Chevy in an HK/HT/HG, that layout is chosen for a broad spread of response on the road. It swaps the cast manifolds for tuned tubes and changes exhaust flow and note; we publish no power or sound data for it. The 1-5/8in primary is a road-oriented size for this engine family.

Will it suit my HK/HT/HG?

It's listed for the Chevrolet 283–400 small-block as fitted to the Holden HK/HT/HG. Engine size within that 283–400 range, plus steering and chassis clearance, all matter, so confirm your exact combination with the workshop first. Header fitment in these early Holdens is tight, and we verify against the car rather than the listing alone.

What does fitting involve at our Illawarra workshop?

Oak Flats Muffler Men supplies and fits Pacemaker Tri-Y headers in-house across the Illawarra. On an HK/HT/HG with a small-block Chev, that means landing both sides in a tight bay and clearing the steering. Tell us your engine and any prior changes and we'll confirm the fit, the lead time on this Pacemaker line and book it in. It's listed to suit rather than guaranteed for every variant.

Stocked and fitted by Oak Flats Muffler Men, the Illawarra exhaust and 4x4 specialist in Oak Flats, NSW.
