Market analysis
Why does the Infiniti QX50 exhaust manifold cost more?
A used Infiniti QX50 exhaust manifold carries a median asking price of $96, which is 26% higher than the GMC Sierra 1500 at $71. Supply also plays a role: GMC Sierra 1500 has 2,181 priced listings versus 155 for Infiniti QX50, and more listings generally mean more choices and more competitive pricing.
Grade A (excellent condition) parts make up 84% of Infiniti QX50 listings compared to 66% for the GMC Sierra 1500, so buyers looking for top-condition units will find more options on the Infiniti QX50 side.
The GMC Sierra 1500 average ($100) runs 41% above its median ($71), 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 GMC Sierra 1500 (2015–2025) but only 5 for the Infiniti QX50 (2015–2020), so the GMC Sierra 1500 data reflects a broader range of generations.
Only 51% of Infiniti QX50 exhaust manifold listings include a posted price (155 of 306 observed) — the rest are "call for price," which usually signals negotiable or higher-than-average pricing.
The GMC Sierra 1500 exhaust manifold is interchangeable across 12 model years versus just 7 for the Infiniti QX50 — that wider compatibility window means more donor vehicles in salvage yards and tends to push prices lower.
At Grade A (excellent) condition, the GMC Sierra 1500 is 26% cheaper ($71 vs $96) — the gap narrows 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.
