Mike and his team are awesome! Super friendly, honest, and quick service. I came in for a smog check and they had me in and out in no time. Prices are fair and you can tell they really care about their customers. Definitely recommend M&N Smog and Muffler to anyone in the Riverside area!

Great fast professional service had a new catalytic converter put on they gave me a fair price and did an excellent job the welds look beautiful. Plus they added an extra hanger to hold it in place better. I’ll be back Two weeks later I came back to get my vehicle smog instead of smogging my vehicle and making me pay for a failure Mike let me know it would not pass. He looked it over and told me exactly what the problem was. I went picked up the part put it on came back the next day and my car passed. That showed me M&M’s honesty and integrity. I really appreciate a honest top mechanic Mike

Had a problem with broken clips and damaged engine splash shield. Mike took my car in and on the spot "jerry-rigged" a solution to put me back on the road. Well done! Grateful for the care and service!
