Market analysis
Why does the Ram 3500 exhaust manifold cost more?
A used Ram 3500 exhaust manifold carries a median asking price of $125, which is 4% higher than the Infiniti Q50 at $120. Supply also plays a role: Ram 3500 has 2,123 priced listings versus 221 for Infiniti Q50, and more listings generally mean more choices and more competitive pricing.
Grade A (excellent condition) parts make up 87% of Infiniti Q50 listings compared to 69% for the Ram 3500, so buyers looking for top-condition units will find more options on the Infiniti Q50 side.
The Ram 3500 average ($167) runs 34% above its median ($125), indicating a tail of high-priced listings — likely low-mileage or remanufactured units pulling the average up.
Our guide covers 11 model years for the Ram 3500 (2015–2025) but only 6 for the Infiniti Q50 (2015–2021), so the Ram 3500 data reflects a broader range of generations.
Only 61% of Ram 3500 exhaust manifold listings include a posted price (2,123 of 3,498 observed) — the rest are "call for price," which usually signals negotiable or higher-than-average pricing.
The Ram 3500 exhaust manifold is interchangeable across 18 model years versus just 7 for the Infiniti Q50 — that wider compatibility window means more donor vehicles in salvage yards and tends to push prices lower.
Buyer's checklist
What to check before buying a used exhaust manifold
- Inspect the casting or tubular welds thoroughly for hairline thermal cracks, especially around collector junctions and bolt holes.
- Check mounting flanges with a straight edge for warping, which causes persistent exhaust leaks even with new gaskets installed.
- Verify oxygen sensor port count, thread condition, and EGR valve port locations, which differ depending on regional emissions equipment.
- Check that cylinder head exhaust port shapes (round vs D-port vs oval) match your engine's cylinder head design.
