Market analysis
Why does the Infiniti QX80 exhaust manifold cost more?
A used Infiniti QX80 exhaust manifold carries a median asking price of $250, which is 42% higher than the Dodge Challenger at $144. Supply also plays a role: Dodge Challenger has 1,615 priced listings versus 184 for Infiniti QX80, and more listings generally mean more choices and more competitive pricing.
The Dodge Challenger average ($183) runs 27% above its median ($144), indicating a tail of high-priced listings — likely low-mileage or remanufactured units pulling the average up.
Only 66% of Dodge Challenger exhaust manifold listings include a posted price (1,615 of 2,459 observed) — the rest are "call for price," which usually signals negotiable or higher-than-average pricing.
At Grade A (excellent) condition, the Dodge Challenger is 33% cheaper ($150 vs $225) — the gap widens compared to the overall median difference.
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.
