Alfa Romeo catalytic converters run about $20 to $300 for one original unit in 2026. V6 units lead at $100 to $300, Giulia and Stelvio units bring $75 to $250, JTDm ceramic units $50 to $200, and metal substrate 2.4 JTDM units only $20 to $75. Establish which type you have before quoting.
Two units, one car, very different numbers
This is the finding that matters most on this brand, and it comes straight from the catalyst databases.
For the Alfa Romeo 159 and Brera 2.4 JTDM, built between 2005 and 2011, two separate entries exist from the same manufacturer, Arvin Meritor. One is recorded with components listed as Metal, with a high over a recent six-month window of just 65 US dollars. The other, under reference 55196244 and 51786867, is recorded as Ceramic.
The reason is straightforward. A metallic substrate is a thin foil structure carrying a much lighter precious metal load than a ceramic honeycomb of the same size, so recovery yields far less. Two units that look broadly similar under the car are not worth remotely the same.
So on this brand, before anything else, work out which you have. A ceramic unit will show a visible honeycomb cell structure when you look into the open end. A metallic one shows fine rolled foil layers instead. If a buyer quotes without asking, that is worth questioning.

Ranges are compiled from published core-buyer code lists, catalyst exchange transaction data and current scrap guides; they are not a live per-code feed. Figures are per unit, and V6 models generally carry two.
The five-brand reference
The MiTo carries what is, by brand count, the most widely shared reference in this whole cluster.
Reference 55217451, a ceramic unit, is catalogued against Alfa Romeo, Peugeot, Fiat, Citroen and Lancia together. The vehicles named are the Alfa Romeo MiTo, Fiat Punto Evo, Doblo and Fiorino, the Citroen Nemo and the Peugeot Bipper. Six vehicles, five badges, one part.
Its high over a recent six-month window was 247 US dollars, which is well above what most owners expect from a small hatchback unit.
That matters practically. If you have a 1.3 MultiJet MiTo and a buyer offers a small-car category price, the reference itself is in their list under four other marques. Quote the number.
Where Alfa reaches outside the Italian family
The Fiat page covers the shared Italian references in detail, and most of them include an Alfa. But one diesel family goes further than that.
A 1.9 JTD reference is listed against the Alfa Romeo 159 alongside the Opel Signum, the Vauxhall Vectra, an Opel Meriva and a Saab 9-3 1.9 TDI. That is the shared General Motors and Fiat diesel of the period, and it means the Opel and Vauxhall figures are fair cross-checks on a 159 unit.
Closer to home, a 1.9 JTD reference covers the Alfa 156, 147 and GT with the Fiat Stilo and Multipla, and another covers the GT with the Lancia Musa and Fiat Bravo.
Where the real money sits
Alfa is the one brand in the Italian group that fitted genuinely large engines, and that is where the range separates from Fiat.
The V6 cars lead: the 166, GT, Brera, Spider and the GTA versions of the 147 and 156. Those units sit at $100 to $300 each and most cars carry two, so a whole vehicle holds $200 to $600.
The modern rear-drive Giulia and Stelvio follow at $75 to $250.
Everything else in the range is four-cylinder and prices accordingly, in the $50 to $200 band depending on engine and whether the unit is petrol or diesel.
Reading an Alfa reference
Alfa units carry several number formats, and it is worth photographing all of them.
Some run with an AL prefix, in strings such as AL 223353116, AL 223316126 and AL 1914720127. Others use an AR prefix, for example AR161240901000. Many carry Fiat group numbering instead, such as 55195359, 51780228, 51785420 and 51767245, sometimes with an H-prefixed variant like H52217433.
Send everything you can read. On a brand where the substrate type changes the value several times over, the reference is what settles it.
Alfa Romeo prices around the world
Platinum, palladium and rhodium settle in US dollars, so an Alfa reference holds the same metal value in every market. Currency and local buyer depth are what change. The table converts the Alfa span into each market’s money at today’s rate.

Alfa sells mainly across Europe, with smaller volumes in North America and elsewhere. The European fleet is heavily diesel, so a European seller is more likely holding JTDm hardware than a V6 unit.
Questions people actually ask
How much is an Alfa Romeo catalytic converter worth as scrap?
Between roughly $20 and $300 for one original unit in 2026. Metal substrate 2.4 JTDM units bring only $20 to $75, petrol four-cylinder and JTDm ceramic units $50 to $200, Giulia and Stelvio units $75 to $250, and V6 units $100 to $300.
Why are two converters for the same Alfa worth different amounts?
Because some were built with a metallic substrate and some with ceramic. For the 159 and Brera 2.4 JTDM, catalyst databases hold separate entries from the same manufacturer for each type, and the metal version shows a recent high of about $65. A ceramic unit of the same size carries a much heavier precious metal load.
How do I tell a ceramic converter from a metal one?
Look into the open end. A ceramic unit shows a honeycomb of square or triangular cells. A metallic one shows fine rolled foil layers instead. On this brand that check is worth making before you accept any quote.
Which cars share an Alfa Romeo MiTo converter?
Reference 55217451 is catalogued against five brands at once: the Alfa Romeo MiTo, Fiat Punto Evo, Doblo and Fiorino, the Citroen Nemo and the Peugeot Bipper. It reached a high of about $247 over a recent six-month window.
Which Alfa Romeo converter is worth the most?
The V6 units fitted to the 166, GT, Brera, Spider and the GTA versions of the 147 and 156, at $100 to $300 each. Most of those cars carry two, so a whole vehicle holds roughly $200 to $600 before pre-cats are counted.
