Find a mechanic for a Catalytic Converter replacement

Catalytic converters are made of precious metals and, therefore, are ridiculously expensive. That’s why, when the time comes for replacement, you’ll want to find a mechanic who can do the job right. Use the following tips to find a qualified professional you can count on.

How to find a mobile mechanic for a Catalytic Converter replacement?

Select a certified professional

The new car smell may be long gone, but that doesn’t mean your car doesn’t deserve the best – even if it’s seen better days. You don’t want just anyone popping the hood and poking around. Look for a certified mechanic who has experience working with your car’s make and model. Also, keep in mind, there are many different areas a technician can specialize in. You’ll want to choose someone who has either A8 Engine Performance certification or X1 Exhaust Systems certification. Both areas of accreditation cover catalytic converter diagnosis and repair.

Do they have a good reputation?

Recommendations, either via word-of-mouth or internet reviews, are a great way to find a stellar mechanic. If a repair business has been around for a long time and has a devoted following, you can bet they operate with intelligence and integrity.

Do they seem professional?

Repair in your driveway should be a professional experience. You’ll know you’re in good hands when a mechanic, in a clean uniform, arrives in a company vehicle equipped with tools and car parts to complete the job. Time to raise your standards.

Don’t be left guessing about quality

Catalytic converter quality varies, as does the caliber of the work being performed. Always ask about warranties when you schedule an appointment. Warranties offer quality assurance and protect you in the rare case that something goes wrong with your repair.

How to find a local repair shop for a Catalytic Converter replacement?

Look for a certified mechanic

Check to make sure the shop is working with only the best, aka ASE certified professionals. In particular, you’ll want to ask whether the mechanic assigned to your car has either A8 Engine Performance certification or X1 Exhaust Systems certification. Both areas of accreditation cover catalytic converter diagnosis and repair. And if the shop doesn’t have the right credentials, move on.

Reputation is everything

The best shops have a loyal clientele – and a packed schedule to prove it. Online recommendations or word-of-mouth suggestions will help you find a mechanic with an outstanding reputation.

Are they helpful?

A good shop will take the time to explain any work your car needs in detail. They will also be honest about pricing (including giving you an estimate for parts and labor) and won’t try to add on any unnecessary repairs.

Do they offer a warranty?

Catalytic converter replacement is a costly job you only want to do once. Ask about warranty coverage when you schedule your appointment. A sound warranty provides peace of mind that you’re getting an OEM-grade catalytic converter and expert repair.

What is a Catalytic Converter?

Catalytic converters, also known as cats (slow down, they don’t scratch), are an emissions control device. Long story short, they use precious metals to transform toxic gases into water vapor and carbon dioxide. Your car has at least one cat, and it’s downstream of the engine.

Symptoms of a failing Catalytic Converter

Failed emissions test

Think of the catalytic converter as the cheat sheet you snuck into your Biology exam in high school. Its entire purpose is to help you pass a test. If your car fails its emissions test, it could be because your catalytic converter is letting you down when you need it most.

Poor performance

Let’s be honest: you’re hitting that gas pedal a little harder than is necessary when the light turns green. We get it. Your car is fun. If it stops being fun, well, you’ve got a problem. A malfunctioning catalytic converter can decrease the power your car has, and even lead to stalling, or an inability to start.

Check engine light

Ahh, yes. Your favorite warning light to completely ignore. The check engine warning light can illuminate for many reasons, including a catalytic converter that forgot how to work. The light, on the other hand, didn’t forget how to work, so try not ignoring it this time.

How urgent is a Catalytic Converter replacement?

Very. There are already roughly 50 million feral cats in the country, so the last thing you want is yours running around, getting busy, and bringing more kittens into the world. Oh, sorry, you meant getting the other cat fixed.

An inefficient catalytic converter isn’t a safety issue, or that much of an inconvenience. But it does pose a serious environmental problem, due to harmful emissions. And if you fail your emissions test, you won’t be able to register your car. And a clogged cat will keep your car from driving properly.

Often times catalytic converters malfunction as a result of a separate issue in the engine, so it’s worth making sure everything else is in working order before replacing the cat.
