Porsche catalytic converters run about $25 to $450 for one original unit in 2026. Cayenne Turbo and V8 units lead at $150 to $450, Panamera V8 units $150 to $400, 911 units $125 to $375, and Cayman or Boxster units $100 to $300. The diesel particulate filter sits at the bottom, and the reason is worth reading.
Plot twist: it is the SUV
The mental image most people bring to this page is a flat six. The market's image is a school run.
The Cayenne has been Porsche's volume vehicle for two decades, so it is the model reaching end of life in numbers, and it carries the largest catalysts in the range. A Cayenne Turbo pair sits at $150 to $450 per unit. A 911 pair sits at $125 to $375. The sports car is not the top of the list, and it was never going to be, because catalyst value tracks engine size and exhaust volume rather than lap times.
Workshop pricing tells the same story from the other end. Replacing a Cayenne converter is estimated at roughly $6,928 to $7,114, the highest figure of any vehicle covered on this site. A 911 comes in at $4,271 to $4,393, a Panamera at $3,346 to $3,437, and a Boxster at $2,799 to $2,879.

The thirty-three dollar Porsche part
This is the detail that keeps expectations honest, and it comes straight from the catalyst databases rather than from opinion.
There is a reference, 7P0254800A, also catalogued as 7P0131709 and 7P6181DA. The databases list it against three marques at once: Audi, Volkswagen and Porsche. The vehicles are a Porsche Cayenne 3.0 diesel, a Volkswagen Touareg II 3.0 V6 TDI, and an Audi Q7 3.0 TDI V6. The component is a diesel particulate filter.
Its high over a recent six-month window was 33 US dollars.
Two things are worth noticing. The first is the part number itself: 7P is the Volkswagen Touareg platform code, printed on a component fitted to a Porsche. The second is the figure. A diesel filter is platinum-bearing but thinly loaded, and no badge changes that.
So if you are holding a diesel Cayenne or Macan, set expectations accordingly. The oxidation catalyst brings $30 to $150 and the filter $25 to $100. That is the honest number, and it has nothing to do with the crest on the bonnet.
Reading the number on the shell
Porsche references are more informative than most, because the leading digits usually identify the model series.
Buyer databases carry Porsche units under numbers such as 99611302256, 99611302253 and 99611302209, where 996 is the 911 generation built from 1997. Others run 93011322801 and 93011322802, where 930 points to the earlier 911. A reference beginning 9A1 belongs to the later flat six family used in the Cayman and Boxster.
The practical benefit is that you can often work out what you are holding from the part number alone, even if the unit has been off the car for years. Photograph every number on the shell and quote those rather than the model name, since the number is what the buyer will look up.
Where the money actually is
Three groups, in order.
The petrol V8s lead: Cayenne Turbo, Cayenne S in 4.5 and 4.8 litre form, and the Panamera. These carry large catalysts, two per vehicle, at $150 to $450 each. A whole car sits at $300 to $900.
The flat sixes follow. A 911 unit brings $125 to $375, and Cayman and Boxster units $100 to $300. Again two per car.
The older transaxle cars, the 928, 944 and 968, bring $75 to $250 where an original survives. After forty years, that qualifier does a lot of work.
One caution specific to this brand: sports cars attract aftermarket exhaust systems more than almost anything else. A high-flow sports cat or a decat pipe is worth $5 to $50, and plenty of 911s and Boxsters have had one fitted at some point. Check for a stamped Porsche reference before assuming.
Porsche prices around the world
Platinum, palladium and rhodium settle in US dollars, so a Porsche reference holds the same metal value in every market. Currency and local buyer depth are what change. The table converts the Porsche span into each market's money at today's rate.
Market Currency Unit Equivalent range United States USD per unit $25.00 to 450.00 United Kingdom GBP per unit £18.49 to 332.87 Canada CAD per unit C$34.58 to 622.39 Australia AUD per unit A$34.69 to 624.46 Germany EUR per unit €21.53 to 387.48 India INR per unit ₹2,364 to 42,546 Bangladesh BDT per unit ৳3,073 to 55,318 United Arab Emirates AED per unit AED91.81 to 1,653 Saudi Arabia SAR per unit SAR93.75 to 1,688 Turkey TRY per unit ₺1,212 to 21,807 South Africa ZAR per unit R398.94 to 7,181 China CNY per unit CN¥167.98 to 3,024
These conversions are the metal-value anchor rather than a local quote. Europe holds the deeper Porsche parc and a far higher diesel share, so a European seller is more likely holding the low-value filter than the V8 units at the top of the table.
Why almost nobody scraps a running Cayenne
Worth stating plainly, because it shapes who is actually reading this.
With replacement estimated near $7,000 and a pair of original units worth $300 to $900 as scrap, no one removes a working converter from a Porsche for the metal. The people selling these units are dismantlers, owners whose converters have already failed, and owners retiring a vehicle for other reasons.
That matters for two practical decisions. If the car is staying on the road, the aftermarket exists: replacement units for a Cayenne list from roughly $120 to $660, against premium branded sets near $1,880 and genuine Porsche parts around $700 to $1,260. Check what your local emissions testing accepts before buying the cheapest option.
If the car is going to a dismantler, sell the original units as cores separately rather than letting them go with the shell. On a V8 Cayenne that is a few hundred dollars that would otherwise leave as steel weight.
Questions people actually ask
Which Porsche catalytic converter is worth the most?
The Cayenne Turbo and V8 units at $150 to $450 each, followed by the Panamera V8 at $150 to $400. Both carry two units, so a whole vehicle holds roughly $300 to $900. The 911 sits below them at $125 to $375 per unit.
Is a Porsche converter worth more than a Volkswagen one?
Not automatically, and sometimes it is literally the same part. Catalyst databases list one diesel filter reference against a Porsche Cayenne, a Volkswagen Touareg and an Audi Q7 together, carrying a Touareg platform part number and a recent high of about $33.
Are diesel Porsche converters worth much?
No. The oxidation catalyst brings $30 to $150 and the particulate filter $25 to $100, because diesel units are platinum-led with almost no rhodium. This is the one part of the Porsche range where the figures are genuinely modest.
How does a Porsche compare with a BMW or Mercedes unit?
At the top they sit close. A Cayenne V8 unit occupies similar territory to a BMW X5 or Mercedes GLE unit, and an Audi Q7 unit shares a platform with the Cayenne outright. Engine size separates them more reliably than the badge.

Frequently asked questions
How much is a Porsche catalytic converter worth as scrap?
Between roughly $25 and $450 for one original unit in 2026. Diesel particulate filters bring $25 to $100, diesel oxidation catalysts $30 to $150, Cayman and Boxster units $100 to $300, 911 units $125 to $375, and Cayenne or Panamera V8 units $150 to $450.
Which Porsche catalytic converter is worth the most?
The Cayenne Turbo and V8 units at $150 to $450 each, then the Panamera V8 at $150 to $400. Both vehicles carry two converters, so a whole car holds roughly $300 to $900. The 911 sits below them at $125 to $375 per unit.
Is a Porsche converter worth more than a Volkswagen or Audi one?
Not automatically, and in some cases it is the same part. Catalyst databases list one diesel filter reference against a Porsche Cayenne, a Volkswagen Touareg and an Audi Q7 simultaneously, under a Touareg platform part number, with a recent six-month high of about $33.
Are diesel Porsche catalytic converters worth much?
No. The oxidation catalyst brings $30 to $150 and the particulate filter $25 to $100, since diesel units are platinum-led with very little palladium and essentially no rhodium. This is the one part of the Porsche range where the numbers are genuinely modest.
What do the numbers on a Porsche converter mean?
The leading digits usually identify the model series. References beginning 996 belong to the 911 built from 1997, 930 to the earlier 911, and 9A1 to the later flat six used in the Cayman and Boxster. Quote the full number rather than the model name.
What does it cost to replace a Porsche catalytic converter?
Workshop estimates put a Cayenne at roughly $6,928 to $7,114, a Macan at $4,920 to $5,194, a 911 at $4,271 to $4,393, a Panamera at $3,346 to $3,437 and a Boxster at $2,799 to $2,879. The Cayenne figure is the highest of any vehicle covered on this site.
