25 Years.
One Owner.
Zero Shortcuts.
Mercey Mathews spent 20 years mastering the automotive trade before opening M&M Muffler in 2000. That's not a career change — it's a credential. What started as a muffler and exhaust shop has grown into a full-service repair operation that Sylvan Hills and southwest Atlanta have relied on for a quarter century.
With women technicians on staff and a reputation built on cost-saving solutions and honest diagnosis, M&M is the shop for people tired of feeling talked down to or overcharged.

First shop where I didn't feel like I was being upsold. They showed me exactly what needed fixing and what could wait. That was eight years ago — still coming back.
