Emissions & Flow Restoration
The Lungs of Your Exhaust
The catalytic converter is a technical masterpiece that converts harmful gases into safe ones. In Algonquin, it has a hard life. It reaches temperatures over 1,000°F and is then blasted with "ice-cold" road salt spray. These extreme thermal shocks can cause the internal ceramic "honeycomb" to crack or melt, leading to a "plugged" exhaust and a major loss of power on IL-62.
The Queens Detail: Beyond the Part
A failed converter is often a symptom of an engine problem. Because we lean into the details, we find the root cause:
- Upstream Health Audit: We check your spark plugs and fuel injectors. If your engine is "running rich," it will send raw fuel into the converter, "melting it" from the inside out.
- Back-pressure Testing: We measure the physical air flow through your exhaust to confirm a restriction before recommending a replacement.
- High-Durability Spec Selection: We only use converters with premium internal loadings designed to meet or exceed Illinois emissions standards and survive our corrosive winters.
- Oxygen Sensor Calibration: We replace or test the sensors that "talk" to the converter, ensuring your engine computer is getting the accurate data it needs for peak efficiency.
Passing the Emissions Test
If your "Check Engine" light is on for an P0420 code, or if your car feels sluggish and smells like "rotten eggs," your converter is failing. We provide the technical expertise to get you back into compliance and back on the road.
I know a catalytic converter sounds like a big, expensive headache. It’s one of those parts you never want to think about. But if yours fails, you’re not just failing an emissions test; you’re losing power and wasting gas.

Frequently Asked Questions
Have questions about our Catalytic Converter Service? Here are some common queries from our customers.

Appointments are recommended, especially for mechanical work and diagnostics, to help us get you in faster. However, we do accept walk-ins whenever our schedule allows.
02 How long will my service take?
Basics like tire installation and alignments are often completed the same day. For diagnostics or larger repairs, we'll give you a clear time estimate before we start any work.
03 Do you provide a quote before starting?
Absolutely. We never perform repairs without your approval. We'll explain what's needed, why it's needed, and exactly what it costs—no surprises.
04 Can I bring my own parts or tires?
In some cases, yes, but we highly recommend using the parts we supply. Our parts are specifically matched to your vehicle and come with our full warranty and testing.

Yes. Most repairs and parts come with a warranty. We'll explain your specific coverage clearly before the work begins so you have total peace of mind.
