You Don't Have to Take Our Word for It!

Here's what some of our satisfied customers have to say about Guaranteed Muffler:

They installed a new muffler in my old Subaru earlier this week. They called me to discuss and gave me a quote (only 99 dollars, including installation!) before beginning work and had my car done exactly when they said they would, which only took a couple of hours even though I did not need the repair done quickly. My car sounds great and I will definitely use them again.


I had a great experience on my first visit to this shop when I needed my brakes replaced. The staff was courteous, prompt and very responsive. I will definitely go back when I need their services.
