Scott's Auto & Clutch provides catalytic converter diagnosis, replacement, and anti-theft shield installation. Whether your converter has failed an emissions test, been stolen, or is causing performance issues, we'll identify the root cause and fix it properly—not just swap the part.
Every repair starts with a thorough diagnosis. We identify exactly what your vehicle needs, walk you through our findings, and get your approval before any work begins. Depending on what we find, the types of work we commonly perform include:
Our experienced mechanics take a thorough approach to every repair.
We find out why the converter is failing before recommending replacement. Installing a new converter on an engine with an underlying issue will fail the new part just as fast.
We install anti-theft shields to protect your catalytic converter—a common target for theft in the Salt Lake Valley.
We use converters that meet Utah emissions requirements and verify the vehicle passes before returning it.
Honest, itemized estimates before any work begins.
From the moment you call to the moment you drive away, we keep you informed every step of the way.
Tell us about a check engine light, sulfur smell, failed emissions test, or stolen converter.
We test converter efficiency, inspect oxygen sensors, and check for underlying engine issues that could cause converter failure.
Clear estimate before work begins.
Replacement, repair, or shield installation based on the diagnosis.
We verify proper operation and emissions compliance.
Our technicians diagnose and repair these problems every day.
A degraded converter can't reduce pollutants to Utah's required thresholds—but the root cause matters before replacing it.
See symptom details →A rotten egg smell indicates the converter can't process hydrogen sulfide, often from a rich fuel condition or a failing converter.
See symptom details →P0420 or P0430 codes indicate reduced converter efficiency—diagnosis determines whether it's the converter or an upstream issue.
See symptom details →Catalytic converters are stolen for their precious metals. We install protective shields that make theft significantly more difficult.
Our shop in South Salt Lake is centrally located in the valley — most customers are within 15 minutes. We service drivers from throughout the greater Salt Lake area.
Catalytic converters contain precious metals—platinum, palladium, and rhodium—that cost hundreds of dollars per ounce. The converter itself is the most expensive exhaust component. We source quality converters and always diagnose the root cause before recommending replacement.
In rare cases, yes. If the converter substrate is intact but an upstream issue caused the failure—a bad oxygen sensor, misfiring engine—fixing the root cause and clearing codes may resolve it. We always find the cause first.
We install catalytic converter anti-theft shields and cages. These bolt-on guards make cutting the converter extremely difficult and time-consuming, deterring thieves. Toyota Tacoma, Prius, and Honda Element are the most targeted vehicles in Utah.
