Our Exhaust & Emissions Services

Muffler & Exhaust Repair

A damaged muffler or rusted-out exhaust pipe can cause loud noise, vibration, and even fumes entering the cabin. We inspect, repair, and replace mufflers, resonators, flex pipes, and tailpipes to ensure proper noise reduction and safe operation.


Catalytic Converter Replacement

Your catalytic converter plays a vital role in reducing harmful emissions. If it becomes clogged, damaged, or stolen—a growing issue—we provide fast, direct-fit replacement to restore performance and compliance with emissions standards.


Oxygen Sensor Replacement

Oxygen sensors monitor your vehicle’s air-fuel ratio and are essential for efficient combustion and accurate emissions readings. A failing sensor can trigger the check engine light or reduce fuel economy. We test and replace faulty O2 sensors with high-quality parts.
