Exhaust System Installations, Performance Upgrades, Repairs, and Specialty Welding

Whether you need affordable exhaust system repairs, are looking to improve your car's performance, sound, or mileage, or want a custom-fabricated exhaust system for a lowered or lifted car with modified suspension, you can rely on Central Auto Repair. Each of our technicians have at least 15 years of experience working on exhaust systems for all makes and models, and we have a large inventory of high-quality OEM and aftermarket parts, including exhaust systems, mufflers, catalytic converters, performance mufflers, and more from trusted brands like FlowMaster, MagnaFlow, Wicked Flow, Miller CAT, and Full Blown Motorsports products. We also have access to local parts distributors for fast ordering, making it possible for us to provide same-day service on most repairs and installations.

Reliable Catalytic Converter Replacement Services to Ensure Your Car Passes Smog Check

Central Auto Repair also specializes in catalytic converter replacement. The catalytic converter is responsible for reducing your car's three most harmful emissions: carbon monoxide, hydrocarbons, and nitrogen oxides. When your car goes in for a smog check, your car is being tested for how well it is reducing these smog-causing emissions. That's why, if your catalytic converter isn't working properly, it's highly unlikely that your car will pass smog.

If your car has recently failed a smog check, bring it in to Central Auto Repair. We will perform a courtesy inspection to determine what repairs are needed and provide you with an upfront quote. If the catalytic converter is damaged or malfunctioning, we can replace it with a state-approved catalytic converter at rates that are much lower than most car dealerships. Our catalytic converter replacements are guaranteed to allow your car to pass its next smog check.
