San Diego Mufflers

We Will Beat Anybody’s Price!


Ace Muffler Shop is one of San Diego's oldest independent muffler shops. For more than 50 years, the Duty family has carried on the tradition of excellent service. We have expert exhaust technicians with decades of experience who will test and diagnose your vehicle's exhaust system free of charge and provide you with a free estimate detailing what repairs you might need. We only replace what needs to be replaced and will gladly explain it to you in detail and show you what needs to be serviced. Parts and labor are guaranteed.

With a wide variety of products and our custom exhaust capability, we can tailor your vehicle's exhaust system to suit your needs and price range. We offer stock, custom and original factory parts. Though most parts are available in our huge stock, we can promptly special order and receive most out-of-stock items.

We have a convenient and easy-to-find location with multiple bays, so we are able to accommodate many vehicles simultaneously. No appointments are necessary, estimates are free and repairs are fast and guaranteed. No wonder we serve thousands of satisfied customers in the San Diego area.
