What Does Guaranteed Muffler Do During a Smog Check?
We inspect your car or truck's emissions-control equipment to measure the number of pollutants your vehicle is emitting.

First, Guaranteed Muffler will analyze your car or truck's OBD computer system, emissions-control system, and check engine light codes for standard warnings that your emissions system is no longer functioning properly.

Next, Guaranteed Muffler will inspect your car or truck's gas cap, ignition timing, exhaust gas recirculation system, fuel, and evaporative system.

Finally, Guaranteed Muffler will perform a Tailpipe Emissions Inspection which measures the type and quantity of any pollutant emitted from your vehicle's tailpipe.

Did You Pass Your Smog Test?
Great! If your vehicle passes a smog check, Guaranteed Muffler will provide you a vehicle inspection report showing your vehicle's results and will electronically send the smog certificate to DMV.

Testimonials

They installed a new muffler in my old Subaru earlier this week. They called me to discuss and gave me a quote (only 99 dollars, including installation!) before beginning work and had my car done exactly when they said they would, which only took a couple of hours even though I did not need the repair done quickly. My car sounds great and I will definitely use them again.
