SERIOUS FLEET & AUTOMOTIVE

Catalytic Converter Repair & Replacement in Houston, TX

If your vehicle is experiencing performance issues, triggering check engine lights, or failing emissions tests, the catalytic converter may be to blame. At Serious Fleet Auto in Houston, TX, we specialize in catalytic converter diagnostics, repair, and replacement for cars, trucks, and fleet vehicles. Our team of certified technicians uses advanced diagnostic tools to assess your emissions system and restore it to peak efficiency-while keeping you compliant with state regulations.

The catalytic converter plays a vital role in reducing harmful emissions by converting toxic gases into less harmful substances before they exit your exhaust. Over time, converters can become clogged, contaminated, or physically damaged, leading to poor fuel economy, sluggish performance, or emissions system failure. We accurately diagnose these issues and offer honest repair or replacement solutions using high-quality OEM or aftermarket converters.

Common signs of catalytic converter problems include rattling noises under the vehicle, sulfur or rotten egg smells, engine misfires, and illuminated check engine lights (often with codes like P0420). Whether your converter is malfunctioning due to age, engine problems, or theft, our shop is equipped to handle the job efficiently and cost-effectively.

We also specialize in fleet catalytic converter services, offering fast turnaround and dependable repairs for commercial trucks, vans, and utility vehicles. Fleet managers trust Serious Fleet Auto to minimize downtime while ensuring every vehicle meets emissions standards.
