Running 1⅞in primary tubing, the Pacemaker PH2662 is a left-and-right header pair listed to fit the RAM 1500 DT 5.7L V8. The 1⅞in primaries are the set's defining spec — a larger primary bore aimed at letting the 5.7 V8 breathe up high rather than chasing only low-down response.
What does 1⅞in primary tubing do here?
Primary tube size is the application call, and at 1⅞in the PH2662 sits at the larger end. Bigger primaries flow more freely once the engine is working hard, which suits a higher-output V8 build over a stock daily after maximum bottom-end punch. On the RAM's 5.7L the headers are the first real breathing change ahead of the rest of the exhaust, so the primary size sets the tone for everything downstream.
Why a left-and-right pair?
This is supplied as a matched left-and-right set, which is how a V8 header job works — one bank each side, each shaped to clear that side of the engine bay, steering and chassis hardware. On the RAM 1500 DT that body-specific routing matters, since a full-size American ute packs the bay tightly. Buying the DT-listed pair means both banks are formed for where this truck actually has room.
What is a header set replacing on the 5.7?
A header set like this swaps the RAM's factory cast exhaust manifolds for mandrel-formed tube runners merged into collectors. The cast manifolds are compact and restrictive; tube runners scavenge each cylinder more cleanly, which is the point of fitting extractors to a V8 in the first place. Here that's combined with the 1⅞in primary choice for a higher-rpm lean.

Common questions
- Why 1⅞in primaries on the RAM 5.7?
- The 1⅞in primary is the larger option and leans toward higher-rpm, higher-output builds on the 5.7L V8. A smaller primary keeps gas speed up for low-down response; this set trades that for freer top-end flow.
- Is the PH2662 a single header or a pair?
- It's supplied as a matched left-and-right pair, one for each bank of the V8, both formed for the RAM 1500 DT engine bay.
- Will it fit my RAM 1500?
- It's listed to fit the RAM 1500 DT 5.7L V8. Confirm your exact build with the workshop before ordering, since the listing is a guide rather than a guarantee.
