What Is Catalytic Converter Service?
The catalytic converter is a part in your exhaust system that cleans up harmful gases before they leave your tailpipe, it's required to pass a Utah emissions test. A warning light with a P0420 code or a failed emissions test often points here, but the root cause matters before replacing it. We also install protective shields, since catalytic converter theft is common in the Salt Lake area. See our service page for how we diagnose the problem.

About Catalytic Converter Service for Midvale Drivers
Midvale's commercial character and I-15/I-215 proximity create an active theft environment. The 7200 South commercial corridor's parking lots are targeted areas.

That's why Midvale drivers bring their catalytic converter service work to us. We diagnose the cause before recommending anything, you'll know exactly what needs to happen before any work begins.
Before your visit: Midvale Prius and hybrid owners should strongly consider a locking converter shield, hybrid converters command scrap prices 3–5 times higher than standard converter scrap value, making hybrids the most frequently targeted vehicles by organized operations.

Frequently Asked Questions: Catalytic Converter Service Near Midvale
Does P0420 always mean a new catalytic converter?
No. P0420 means converter efficiency is below threshold, which can result from the converter itself or from upstream conditions: rich fuel trim, misfires, a failing O2 sensor, or an exhaust leak. We verify the root cause before recommending a replacement. Installing a new converter on an unresolved engine condition will fail the new part.
How long does a catalytic converter last?
Most OEM converters last 100,000–150,000 miles under normal conditions. Premature failure is almost always caused by an underlying engine condition (misfires, rich running, oil consumption) rather than the converter simply wearing out.
Is it worth installing an anti-theft shield?
For vehicles that are common theft targets (Toyota Prius, Honda Element, older Toyota trucks), absolutely. The shield cost is a fraction of what converter replacement costs. We can tell you whether your specific vehicle is a frequent target in this area.
How does a catalytic converter actually work, and what damages it?
The converter uses precious metals on a ceramic substrate to convert carbon monoxide, unburned hydrocarbons, and nitrogen oxides into less harmful compounds. Misfires send unburned fuel into the converter that burns at temperatures far beyond its design limit, melting the ceramic. Rich running and oil or coolant intrusion coat the substrate and deactivate it. Any of those underlying conditions must be fixed before a new converter is installed.
What do you check before recommending a converter replacement?
We check fuel trims, O2 sensor response quality (upstream and downstream separately), freeze-frame misfire data from when the code set, and for exhaust leaks upstream that could introduce air near the sensor. Only after ruling out those conditions do we recommend the converter. This prevents replacing a $400 to $1,200 part on an engine that will fail it again.
How do anti-theft shields work?
They're heavy steel covers that bolt around the converter and require specialized removal tools. A thief with an angle grinder can cut an unprotected converter in under two minutes. Most will skip a shielded vehicle and move to an easier target. We install them as a standalone service or alongside any exhaust repair.
Is there a warranty on the repair?
Yes. Every repair we perform is backed by a 2-year parts and labor warranty. If something we fixed gives you trouble within two years, bring it back and we make it right at no charge.
How does your pricing compare to dealers and chain shops?
Our labor rates and parts pricing are consistently below dealer rates, typically 20–40% less for the same repair. We use quality parts and back every job with a 2-year parts and labor warranty. You get a written estimate before any work starts so there are no surprises.
Do you offer towing if my vehicle can't be driven?
Yes. If your repair totals over $1,000, we cover the tow to our shop. You shouldn't have to pay to get your car here on top of dealing with the breakdown. Call us and we'll arrange it.
