The bottom line: Online car buyers deal with a bad exhaust system every day and will still make you an offer, though the problem shuts most buyers out.
Private buyers price in the repair cost or skip the car entirely. Dealers discount it before making any offer.
Offers changed a lot with the car type, and the buyer offering the most wasn’t always the same. We quoted 5 cars at Peddle, Wheelzy, and CashForCars, with problems from manifold leaks to catalytic converter failures.
Getting 2 to 3 quotes takes about 5 minutes and can mean hundreds of dollars more.

Key Takeaways
- Who buys it: All three instant buyers priced our smaller exhaust-fault cars online, while dealers mark the fault down, so quote yours with Peddle, Wheelzy and CashForCars.
- What buyers offered: Buyers offered $430 to $1,180 for our five exhaust-fault vehicles, 2003 to 2005 with 97,650 to 208,310 miles, the top for a diesel F-250 and no more than $462 for the rest, so expect a few hundred unless yours is a diesel truck.
- Who offered most: Peddle alone gave online offers on our two F-250 trucks, while on the three smaller vehicles CashForCars or Wheelzy led, all within $32, so a heavy-duty truck starts with Peddle.
- Watch out for: Say on each form whether the catalytic converter is still on the car, since Peddle and Wheelzy both ask about it and the driver checks for it at pickup.
- Selling it yourself: Facebook Marketplace buyers can test-drive a loud car and eBay Motors reaches home mechanics, and either may offer more but will haggle, so list a leak or muffler fault there.
- Your state: Some states, California among them, make the seller pass an emissions test for a private sale, so there a car whose converter has failed goes to an instant buyer.
- Fix or sell: A catalytic converter runs $2,280 to $2,480 at RepairPal, more than any offer in our test, and a muffler at $1,138 to $1,190 tops every smaller car’s offer, so sell a car like these as it is.

Best Places to Sell a Car with Exhaust System Problems
Best For Consistent Offer Amounts: CashForCars

Our take on CashForCars: CashForCars buys cars in any condition, including those with exhaust leaks, catalytic converter problems, and misfires caused by exhaust damage. They’re owned by Copart, the large vehicle auction company, which means they have the resale network to handle cars with mechanical problems that other buyers pass on. They gave us instant quotes on 3 of the 5 exhaust-problem cars we tested.
Pros
- Gives instant quotes on cars with exhaust leaks, catalytic converter failures, and misfires without requiring a phone call in most cases.
- Backed by Copart’s auction network, which gives them more resale channels for exhaust-damaged vehicles than smaller buyers.
- Free towing whether the car runs or not, including cars too loud or smoky to drive because of exhaust damage.
Cons
- Required a phone call for 2 of the 5 exhaust-problem cars we submitted, both of which were Ford F250 trucks.
- Payment usually comes by check rather than cash, so you wait for it to clear before you can spend it.
- The driver may lower the offer at pickup if the exhaust damage is worse than described in the online form.
Why we picked it: CashForCars earned the consistent offer amounts label by coming in above Peddle on the Nissan Xterra, the Ford Focus Wagon, and the Mercedes-Benz C, and leading on the Focus Wagon and the Mercedes. The Copart backing seems to help CashForCars price common passenger cars and SUVs with exhaust issues more aggressively than services that don’t have that resale network behind them.
What CashForCars says about buying cars with mechanical problems:
Best For Older High-Mileage SUVs: Wheelzy
Wheelzy buys cars in any condition, running or not
- Buys cars without keys
- Buys cars missing parts, engine and transmission in
- Pays cash or check at pickup
- Quote often needs a phone call

Our take on Wheelzy: Wheelzy buys junk, damaged, and non-running cars, including those with exhaust leaks or manifold failures. Their quote form takes about 2 minutes and asks for your vehicle details and whether the car starts and drives. Say on the form if the catalytic converter is missing or aftermarket, because Wheelzy’s terms let it lower the offer at pickup over the converter, and you can turn the new offer down.
Pros
- Offered the most on the 2003 Nissan Xterra with an exhaust leak, beating both Peddle and CashForCars on that SUV.
- Offer holds at pickup when the exhaust problem is as you described and the catalytic converter is original.
- Free towing even if the exhaust problem makes the car too loud or smoky to drive to a drop-off point.
Cons
- Required a phone call for 2 of the 5 exhaust-problem vehicles we submitted, both of which were high-mileage trucks.
- Came in below CashForCars on the Focus Wagon and Mercedes, so the edge over competitors isn’t consistent across all car types.
- Some BBB complaints mention last-minute price changes at pickup, so describe the exhaust damage as accurately as possible upfront.
Why we picked it: Wheelzy offered the most on the 2003 Nissan Xterra with an exhaust leak. That SUV had 203,420 miles and a clean title, and Wheelzy’s $462 came in $32 above Peddle’s and $10 above CashForCars’. If you have an older high-mileage SUV with exhaust problems, Wheelzy is worth checking before you accept any other offer.

Our take on Peddle: Peddle buys cars with any kind of mechanical issue, including exhaust system failures. Their support team confirmed they make offers on cars with exhaust leaks, including vehicles that start but don’t drive well because of the issue. Peddle’s quote form asks about starting and driving conditions, so when you describe an exhaust problem, they factor that into the instant offer rather than routing you to a callback.
Pros
- Gave instant online quotes on all 5 exhaust-problem vehicles, including the diesel F250 that both Wheelzy and CashForCars sent to a phone call.
- Up to seven days to accept the offer.
- Confirmed via their support chat that they buy cars with exhaust leaks and catalytic converter problems.
Cons
- Gave the same flat offer on 4 of the 5 exhaust-problem cars, suggesting limited price variation for common makes with exhaust issues.
- Offers can change at pickup if the driver finds exhaust damage that wasn’t fully described in the online form.
- Pickup windows are 4-hour blocks rather than a set time, and payment is usually by check rather than cash.
Why we picked it: When we submitted the 2005 Ford F250 diesel, both Wheelzy and CashForCars came back asking for a phone call. Peddle produced an instant quote of $1,180, making it the only buyer that could price that vehicle without a callback. If your exhaust problem involves a diesel truck or a vehicle with multiple compounding issues, Peddle is the most reliable starting point for getting an online number without waiting.

Best For Negotiating Your Offer: CarBrain
CarBrain specializes in wrecked and broken-down vehicles

Our take on CarBrain: CarBrain has been buying problem cars since 2007. They buy vehicles with exhaust problems, catalytic converter issues, and other mechanical failures. When we got a quote, their form also let us counter the first offer. That leaves you a bit more room to negotiate.
Pros
- Lets you counter their first offer on exhaust-damaged cars, giving you more control than most instant buyers who give you a fixed take-it-or-leave-it number.
- Buys cars with exhaust problems, catalytic converter failures, and other mechanical issues that cause dealers to say no.
- Payment happens before the tow truck leaves your location, so the car doesn’t go until you have the check in hand.
Cons
- Won’t buy cars with the engine or transmission missing, so if the exhaust damage has caused additional major component failure, that may affect eligibility.
- Offers tend to run lower than some competitors for similar exhaust-damaged cars, so always compare before accepting.
- Asks for photos of your title and ID before pickup on some cars, which adds a step compared to services that only need your description.
Why we picked it: CarBrain’s counter-offer option is the key reason it’s on this list for exhaust problem sellers. When the pool of buyers is smaller because of a known mechanical issue, having the ability to push back on a first offer can matter. CarBrain’s quote form allowed this for us, which gives you more control than a single fixed take-it-or-leave-it number.
Best For Nationwide Auction Buyers: eBay Motors
eBay Motors lists your car to buyers nationwide
- Listing fee is $34 or $79
- 40 photos with either fee
- No percent fee on sale price
- 2.8% fee on deposits via eBay
-
Buyer reach 25% 3/5
-
Safety features 25% 4/5
-
Listing cost 20% 3/5
-

-
Ease of listing 15% 3/5
Our take on eBay Motors: eBay Motors is an online listing platform that connects you with car shoppers across the country. For a flat listing fee of $34, or $79 above a $15,000 price, you can list your car with up to 40 photos and a full description, and reach buyers nationwide who might be looking for a project car or a parts vehicle. Cars with exhaust problems often attract buyers who are comfortable doing their own repairs, and that national reach helps you find them.
The trade-off is all the work falls on you. You write the listing and answer buyer questions, and eBay expects the buyer to arrange pickup or shipping. Buyers on the platform will likely negotiate once they see the exhaust issue, so price with some room to come down.
Best For Free Local Listings: Facebook Marketplace
With Facebook Marketplace you sell your car directly to local buyers
- Sell directly to local buyers
- Chat through the platform only
- Post in local buy/sell groups
-

Ease of listing 15% 5/5
Our take on Facebook Marketplace: Facebook Marketplace is free to list and puts your car in front of local buyers immediately. Cars with exhaust problems sell best here when priced to reflect the issue. Also post in local buy and sell groups on Facebook to reach more buyers looking for a project car or parts vehicle.
Expect buyers to ask about the exhaust issue directly and use it to negotiate the price down. You’ll also handle all the meetups, test drives, and paperwork yourself. Selling privately takes more time and effort, but you keep more of the final price than you would with an instant buyer.

What This Tells Us
What this tells us:
- CashForCars, backed by Copart’s auction network, consistently offered more than Peddle on smaller gas-powered cars and SUVs with exhaust issues. That Copart backing likely gives them more resale channels for these vehicles than buyers without that network.
- Peddle gave the same flat offer on 4 of the 5 vehicles, suggesting a set floor for common cars with exhaust problems regardless of make or model. The exception was the diesel truck, where the vehicle type and higher value pushed the offer well above that floor.
- Wheelzy routed 2 out of 5 vehicles to a phone call, and both were trucks. The gas-powered sedan, wagon, and SUV all got instant online quotes from Wheelzy, but the trucks did not. This suggests Wheelzy may price trucks with exhaust issues differently than passenger cars.
- CashForCars also routed 2 out of 5 vehicles to a phone call, and both were Ford F250 trucks. CashForCars gave instant quotes on the Xterra, Focus Wagon, and Mercedes, so the truck type seems to be the trigger rather than exhaust problems in general.
- When the diesel truck came up, Peddle was the only service to produce an instant online quote. If you have a diesel vehicle with exhaust problems, Peddle is the most likely to give you a number without requiring a call back.
- CarBrain’s counter-offer option becomes more valuable when fewer buyers can give you an instant number. If CashForCars and Wheelzy both route your vehicle to a phone call, CarBrain’s ability to negotiate may help you close the gap.
- Facebook Marketplace and eBay Motors can bring more money than instant buyers, but expect a buyer who knows about the exhaust issue to push on price. Be transparent in your listing and price with some room to negotiate.
- Getting quotes from more than one buyer takes about 5 minutes total and can mean hundreds of dollars more in your pocket, especially if your car is a truck or has multiple compounding issues alongside the exhaust problem.
- All three buyers reduce their offer when a catalytic converter is missing. The original cat holds precious metal scrap value that aftermarket and removed units don’t match. In our offer data, buyers offer about 57% less for a car with its catalytic converter gone than for a comparable car with it. Describe the exact state of your catalytic converter accurately before submitting, since this is one of the most common reasons an offer changes at pickup.

Frequently Asked Questions
Does Peddle buy cars with exhaust problems?
Yes. Peddle confirmed via their chat support that they make offers on cars with exhaust problems, including exhaust leaks.
When the quote form asks whether the car starts and drives, choose “No, it starts but doesn’t drive” for any exhaust leak. A muffler problem alone counts as “Yes, it starts and drives.”
In our test, Peddle gave instant online quotes on all 5 vehicles with exhaust issues, making them the most reliable service for getting a number without a phone call.
Does Wheelzy buy cars with exhaust leaks?
Yes. Wheelzy buys damaged and non-running cars, including those with exhaust system issues.
Their quote form includes condition questions, and exhaust leaks fall under drivability problems. In our test, Wheelzy gave instant quotes on 3 of the 5 vehicles with exhaust problems.
For the two trucks in our test, Wheelzy asked us to call for a quote instead of showing an instant number online.
Does CashForCars buy cars with exhaust problems?
Yes. CashForCars states on their website that all vehicles with mechanical problems have value, and they buy cars with exhaust issues, misfires, and catalytic converter problems.
They gave instant online quotes on 3 of the 5 vehicles in our test.
For both Ford F250 trucks, CashForCars asked us to call for a quote rather than showing an instant number. If you have a truck with exhaust problems, expect to make a call.
Does CarBrain buy cars with exhaust issues?
Yes. CarBrain buys cars with mechanical failures including exhaust problems, catalytic converter issues, and cracked manifolds.
They won’t buy cars with the engine or transmission missing, but exhaust system damage alone doesn’t disqualify a car.
Should I fix the exhaust before selling?
It depends on the repair cost. A minor exhaust pipe or flange repair could open up more buyers and improve your offer.
Before deciding, get a repair estimate so you can compare it against the offer you’d receive as-is.
If the repair cost is close to or exceeds what you’d gain in sale value, selling as-is to an instant buyer is often the better move.
Get a free estimate from RepairPal to compare repair costs against your car’s value before deciding.
How much does an exhaust problem reduce a car’s value?
It depends on the severity and the car’s baseline value. A minor exhaust leak on an older car may reduce the offer a little compared to the same car in working condition.
A failed catalytic converter, cracked exhaust manifold, or severe rust through the exhaust system can reduce the offer more, especially for cars that fail emissions testing because of it.
In our test, cars with exhaust issues received offers ranging from $430 to $1,180. The vehicle type, mileage, and title status all played a bigger role in the offer amount than the specific exhaust problem.
Can I sell a car with a bad catalytic converter?
Yes. Buyers like Peddle, Wheelzy, CashForCars, and CarBrain all buy cars with catalytic converter problems. The catalytic converter contains precious metals and has scrap value of its own, which buyers price into their offers.
That said, there are two situations that reduce the offer further than a simple cat failure. First, if the catalytic converter has been removed entirely, buyers lose that scrap value and will lower the offer to reflect it.
Second, if the original cat was replaced with an aftermarket one, it contains less precious metal than the factory unit, so it’s worth less to the buyer at resale.
Disclose both situations upfront. Peddle names a missing catalytic converter as damage that can change the offer at pickup. Its form counts an aftermarket converter as attached, so answer yes. If the driver lowers the price because the converter is aftermarket, you can refuse before the car is loaded.
Private buyers are more likely to walk away from catalytic converter issues entirely because of the repair cost and emissions test concerns.
Instant buyers deal with these cars regularly and price the issue in rather than rejecting the car.
Can I sell a car with exhaust problems on Facebook Marketplace or eBay Motors?
Yes, but be transparent about the issue in your listing. Buyers on Facebook Marketplace and eBay Motors will use the exhaust problem to negotiate the price down, so price with room to come down.
On eBay Motors, you can reach buyers nationwide who may want the car for a project or parts, which can work in your favor.
Both platforms leave the photos, description and meetups to you. On eBay Motors, a buyer who checks out with Secure Purchase has Caramel handle the paperwork. You’ll likely get more money than from an instant buyer, but it takes longer and involves more work.
What exhaust problems make a car hardest to sell privately?
Failed catalytic converters are the hardest. They’re expensive to replace and prevent the car from passing emissions testing, which rules out private buyers in most states.
Cracked exhaust manifolds and severe rust through the exhaust pipes are also difficult because buyers can hear or smell the problem before they even look under the car.
For these kinds of issues, instant buyers like Peddle, Wheelzy, and CashForCars are often the most practical option because they deal with exhaust-damaged cars regularly and won’t walk away because of the smell or sound.
Methodology
We selected 5 vehicles with exhaust system problems for this test. The vehicles were: a 2003 Ford F250 Regular Cab (97,650 miles, clean title, exhaust manifold leak on the passenger side), a 2003 Nissan Xterra SE SC (203,420 miles, clean title, exhaust leak), a 2005 Ford F250 Extended Cab diesel (208,310 miles, clean title), a 2005 Ford Focus ZXW Wagon (170,000 miles, salvage title, exhaust manifold leak), and a 2005 Mercedes-Benz C 230K Sport Sedan (105,000 miles, clean title, exhaust leak and possible catalytic converter issues).
We submitted each vehicle to Peddle, Wheelzy, and CashForCars using a Florida zip code. We answered all form questions honestly, accurately describing each car’s exhaust issues and drivability. We took screenshots of every result at the time of submission.
We did not accept any offers. Your results will vary based on your location, your car’s exact condition, and which buyers are active in your area at the time you submit.
