American Muffler handles exhaust system work at 7849 Raytheon Road in San Diego. They build custom systems, install performance mufflers, repair damaged exhaust, and diagnose smog failures.

You can bring in an exhaust system you bought online and they'll install it leak-free. They also build custom exhaust from scratch using 2-4 inch pipe sizes. Their build options include:

• •X-pipe and h-pipe configurations
• •True dual exhaust systems
• •Open-pipe cutouts and turn downs
• •Cat-back systems for diesel trucks

They stock performance mufflers from Borla, Diamond Eye, Flowmaster, Flowpro, and Magnaflow. Whether you want a deeper, more aggressive tone or need a stock replacement, they can source it.

If your muffler has holes or your exhaust took damage from road hazards or a collision, they repair rather than replace when possible. This matters because collision centers and body shops can save customers hundreds or thousands by avoiding full exhaust replacement.

They handle:

• •Pipe straightening and hole/leak repair
• •Exhaust hanger repair
• •Exhaust seal replacement
• •Muffler repair and welding
• •Rusty or bent pipe sections

"I had other mechanics tell me I may need an entire new exhaust system put into my car and then I was recommended to American Muffler. They could have easily taken advantage of me and charged me to replace anything on the exhaust system. Instead they told me the problem was a simple flex tube repair and it saved me a lot of money." — James E., San Diego

Failing a smog check in California typically points to one of these parts:

Catalytic converters remove carbon monoxide and other impurities. When they clog or fail, your vehicle's performance drops, fuel mileage suffers, and emissions spike. American Muffler stocks converters for most import and domestic vehicles, both OBD1 and OBD2 compliant. California law requires direct application lookup for catalytic converters—they follow this.

Oxygen sensors read what's in your exhaust and tell the computer to adjust. Bad sensors trigger check engine lights. They replace sensors and repair or weld in new bungs if needed.

They typically get cars back on the road the same day.

Brent and Andy run the shop. Repeat customers mention they do custom welding for project cars and handle newer vehicles with the same care.

"I've been bringing my cars here for years, Brent & Andy have always taken care of anything I need. They have done custom welding for my older project cars and have worked on my newer cars as well." — Manuel C., San Diego
