Amazing service. These guys went above & beyond to save my engine, I can't say enough good thing about them! The fella at the front even listened to a weird noise my car was making & explained what the issue could be. They seem very honest & professional. Would recommend 🙌

I made an appointment to have my muffler checked at Mr Muffler in Johnstown due to noise increasing in that area. My wife and I were treated with kindness and respect from the first call to set up the appointment until the receipt and keys were handed back to us after the job was completed. We received a complete diagnosis of the problem and how it would be fixed. The job was completed quickly and efficiently, and the price was super reasonable. Don't think twice about letting these guys handle your vehicle. My impression is they are super nice and genuine. Will definitely turn to them in the future with any vehicle trouble I may face.

I just moved to the area and feel incredibly lucky to have found this shop. They’re friendly, extremely knowledgeable, and refreshingly honest—no upselling, no ripping you off, just great old-school service from people who truly care about their customers. It’s rare to find a mechanic like this anymore. They’ve 100% gained a customer for life!

We have used Mr. Muffler twice now and please DO NOT hesitate to take your car here. So friendly, so accommodating and will NOT pressure you to do more than needed. We've had our car towed here twice and they have always fixed what we needed in a very timely manner. Awesome place! Highly recommend

Friendly, helpful and efficient, this location helped me out of a HUGE jam, being out of town on vaca and at a loss for a sudden exhaust pipe repair.
I can't thank these guys enough, especially Steve who did the work, for taking my baby right in and getting her fixed up and letting me drive back to Youngstown NOT sounding like a ghetto mess, LOL.
HIGHLY recommended!
