Understanding “Rent a Cat”: The Catalytic Converter Solution
When mechanics like me talk about “rent a cat,” we’re not suggesting you borrow a furry feline for the weekend. We’re referring to temporary catalytic converter rentals – a practical solution for drivers facing emissions test failures or repair delays. This service has become increasingly popular as catalytic converter theft continues to rise across the country, leaving many vehicle owners in a tough spot.
Catalytic converters are essential emission control devices that transform harmful engine exhaust into less toxic substances. When your converter fails or gets stolen, renting one temporarily can be a lifesaver, especially if you’re facing an emissions test deadline or can’t afford an immediate replacement.
I’ve been helping drivers navigate catalytic converter issues for over 15 years, and I’ve seen firsthand how rental services can provide much-needed breathing room. Whether you’re waiting for an insurance claim to process or saving up for a permanent replacement, a rental cat can keep you legally on the road without breaking the bank.
Why Consider Renting a Catalytic Converter?
There are several compelling reasons why renting a catalytic converter might make sense for your situation:
- Emissions test deadlines looming with insufficient time for permanent repairs
- Waiting on backordered parts during supply chain disruptions
- Temporary solution while insurance processes a theft claim
- Cost-effective option for older vehicles where full replacement isn’t economical
- Buying time to research and compare prices on permanent replacements
I recently worked with a customer whose 2010 Honda Accord failed emissions due to a deteriorated converter. With registration renewal due in just three days, there simply wasn’t time to order and install a permanent replacement. A rental converter got her through the test, giving her a full month to shop around for the best deal on a quality replacement.
For older vehicles especially, the math often makes sense. When I see a 15-year-old car that might only be worth $3,000 needing a $1,500 converter replacement, a $200 rental for passing emissions becomes the more practical solution, particularly if the owner is considering replacing the vehicle within a year or two.
How Catalytic Converters Work
Before diving deeper into rental options, it helps to understand what you’re actually renting. Catalytic converters are fascinating devices that perform chemical magic on your exhaust gases.
Inside each converter is a honeycomb structure coated with precious metals – typically platinum, palladium, and rhodium. As your exhaust flows through this structure, these metals act as catalysts, triggering chemical reactions that convert harmful compounds into less harmful ones.
Specifically, catalytic converters transform three dangerous emissions:
- Carbon monoxide (CO) becomes carbon dioxide (CO2)
- Hydrocarbons (HC) become carbon dioxide and water
- Nitrogen oxides (NOx) break down into nitrogen and oxygen
When functioning properly, a catalytic converter reduces your vehicle’s toxic emissions by approximately 90%, according to EPA research. That’s why they’re mandatory equipment on all gasoline vehicles manufactured since 1975, and why passing an emissions test without one is virtually impossible.
Rental converters work exactly like permanent ones, though they may be universal fit models rather than direct-fit OEM replacements. They’ll get you through emissions testing, but may not be designed for long-term use on your specific vehicle.
Top Catalytic Converter Rental Services
After testing and reviewing numerous services, I’ve identified the most reliable catalytic converter rental providers. Each has strengths for different situations:
1. QuickCat Rentals

The Catalytic Converter Rental Process Explained
Understanding what to expect makes the rental process much smoother. Here’s how it typically works:
1. Initial Contact and Vehicle Assessment
You’ll provide your vehicle’s make, model, year, and engine size. Most services will also ask for your VIN to verify exact specifications. Some may request photos of your existing converter or exhaust system to confirm compatibility. Be prepared to explain your specific situation – whether you’re preparing for emissions testing, dealing with theft, or waiting for parts.
2. Converter Selection and Rental Agreement
Based on your vehicle specifics, the service will recommend appropriate converter options. You’ll select your rental duration (typically 3-14 days) and review the rental agreement, which specifies return deadlines, deposit requirements, and any penalties for late returns or damage. Read this carefully – policies vary significantly between providers.
3. Payment and Deposit
You’ll pay the rental fee upfront along with a refundable deposit. Deposits typically range from $500-1000 depending on the converter type, as these devices contain valuable precious metals. Most services accept credit cards, and some now offer digital payment options like PayPal or Venmo.
4. Delivery and Installation
The converter will be shipped to your address or to a partnering mechanic shop. Delivery typically takes 1-3 business days, though expedited shipping is usually available. Installation can be handled several ways:
- Professional installation through a partner shop (additional fee applies)
- Mobile installation service (where available)
- DIY installation with provided instructions (for mechanically-inclined customers)
5. Testing and Usage
Once installed, you’ll use the converter for your emissions test or temporary driving needs. Most rentals include a brief testing period to ensure proper operation before you take your emissions test. Keep all paperwork and receipts, as some testing facilities may request documentation of the rental.
6. Return Process
When your rental period concludes, you’ll remove the converter (or have it professionally removed) and return it using the provided shipping materials. The service will inspect the returned unit for damage and process your deposit refund, which typically takes 3-7 business days to appear on your account.
Cost Comparison: Renting vs. Replacing
Let’s break down the numbers to help you make an informed decision:
Rental Costs
Typical catalytic converter rental expenses include:
- Rental fee: $100-300 depending on vehicle and converter type
- Refundable deposit: $500-1,000
- Installation (if not DIY): $50-150
- Return shipping: $25-40 (sometimes included in rental fee)
Total out-of-pocket cost: $175-490, with most of the deposit returned
Replacement Costs
Permanent replacement expenses vary significantly by vehicle:
- Economy cars (4-cylinder): $800-1,200 installed
- Mid-sized vehicles (V6): $1,200-1,800 installed
- Trucks and luxury vehicles (V8): $1,500-3,000+ installed
- Hybrid vehicles: $1,800-3,500 installed
These figures explain why many drivers turn to rental options, especially for older vehicles or temporary situations. The Consumer Reports analysis on catalytic converter costs shows prices have increased over 30% in the past three years, making rentals an even more attractive option.
I recently worked with a customer facing a $2,200 replacement for his 2012 Toyota Prius. Since he was planning to trade in the vehicle within six months, we opted for a $199 rental to pass emissions, saving him over $2,000 on a component he would have used for just half a year.
Choosing the Right Rental Service
Not all rental services are created equal. Here’s what to look for when making your selection:
Vehicle Compatibility Verification
The most important factor is ensuring the service has converters compatible with your specific vehicle. Look for services that verify compatibility through VIN numbers rather than just general make/model information. Ask specifically about your engine configuration and exhaust system type.
Clear Deposit Policies
Given the substantial deposits involved, understand exactly what conditions must be met for a full refund. Reputable services have transparent policies regarding damage assessment, cleaning requirements, and return timeframes.
Installation Support
Unless you’re comfortable with exhaust work, prioritize services offering installation assistance through partner shops or mobile technicians. Even if you’re handling installation yourself, services providing detailed instructions and support lines can be invaluable.
Flexible Duration Options
Look for services offering rental periods that match your needs. Some provide weekend-only rentals at reduced rates, while others offer extended rentals for those waiting on parts or insurance claims.
Responsive Customer Service
Technical issues don’t observe business hours. Services with extended support hours or weekend availability provide peace of mind if you encounter problems during installation or testing.
In my experience, the rental services that provide the smoothest experience are those that take time to understand your specific situation rather than simply processing an order. A good provider will ask about your timeline, discuss your vehicle’s condition, and recommend the most appropriate solution.
DIY Installation Tips
If you’re mechanically inclined and looking to save on installation costs, here’s my professional guidance for DIY converter installation:
Safety First
Always let the exhaust system cool completely before beginning work – converters can reach temperatures of 1,200+ degrees during operation. Work in a well-ventilated area, use proper jack stands (never rely solely on a jack), and wear eye protection and gloves.
Necessary Tools
- Socket set and wrenches
- Penetrating oil (crucial for rusty bolts)
- Safety glasses and gloves
- Jack and jack stands rated for your vehicle’s weight
- Replacement gaskets (if applicable)
- Anti-seize compound for new connections
- Oxygen sensor socket (if sensors need removal)
Preparation Steps
Spray all bolts and connections with penetrating oil at least 30 minutes before attempting removal – this dramatically improves your chances with rusted hardware. Take photos of the original installation from multiple angles before disassembly to reference during reinstallation. Make sure the rental converter matches the orientation of your original unit before removing the old one.
Common Installation Challenges
The most common difficulties involve rusted or seized bolts and studs. Never force these – additional penetrating oil and gentle tapping can help break corrosion bonds. Heat from a propane torch can be effective for stubborn bolts (but use extreme caution around fuel lines and flammable materials).
If your vehicle uses oxygen sensors, transfer them carefully from the old converter to the rental, using the proper oxygen sensor socket. Cross-threading these expensive components is a costly mistake.

Common Issues and Troubleshooting
Even with careful planning, you might encounter these common challenges:
Check Engine Light After Installation
If the check engine light illuminates after installing your rental converter, don’t panic. This could indicate:
- Oxygen sensors need to be reset (some vehicles require dealer-level tools for this)
- Exhaust leaks at connection points
- ECU needs time to adjust to the new converter (sometimes requires several drive cycles)
Most rental services offer technical support for these issues. Start by checking all connections for leaks, then contact the service if problems persist.
Emissions Test Failures
If your vehicle fails emissions testing with the rental converter, several factors could be at play:
- The converter hasn’t reached operating temperature (some require 15-20 minutes of driving)
- Other emission system components are failing (fuel mixture issues, EGR problems, etc.)
- The converter isn’t properly matched to your vehicle’s specific requirements
Most reputable rental services offer guarantees for emissions testing and will work with you to resolve issues or provide a different converter if needed.
Fit and Clearance Problems
Universal converters sometimes require minor adjustments for proper fit. If you encounter ground clearance issues or misaligned connections:
- Check if adjustable hangers can provide better alignment
- Consult with the rental service about alternative mounting options
- Consider professional installation if DIY adjustments seem beyond your comfort level
In my shop, we keep a variety of exhaust adapters and flexible connectors specifically for rental converters that don’t perfectly match OEM configurations. Most installation challenges can be overcome with the right adapter pieces.
