Absolutely amazing, accommodating people. Not only did they get me right in, they fixed my exhaust issue quickly and inexpensively. Less than an hour. Could not recommend more.
Jason over there and guaranteed muffler is awesome. Did exactly what I needed. I even had to send someone over there to collect my car for me since I was out of town when the work was done and Jason was polite professional with the individual I had dealing with him. If I could give this post a thousand stars I would
I have been taking my vehicles to Garenteed Muffler since I was around eighteen. Now in my 40s I was just there last week. I have never been disappointed with any repairs or any work. Extremely professional, quality work and fair pricing! Jason is awesome! And we have the same name.
They did great work! They fixed my exhaust leak in no time and reasonable prices too. Theyre very busy so call ahead and schedule time.
Called on a Monday about a rattling exhaust, dropped of my rig the next day, picked it up fixed at noon. Price was reasonable, no runaround, and cant recommend enough.
I had an emergency when my road king exhaust broke. I brought the y pipe in and these guys welded it up stronger than before and didn’t charge me a penny. Great guys with great skills and big hearts. Very impressed and will be bringing all my exhaust needs to this shop!!
So fast, thorough, affordable and all around excellent customer service. Will definitely do business with them again!!
They were very attentive and customer service oriented. The staff communicated well about what they were doing and why... love that in a car shop.
These guys are awesome and multiple times helped me out in a pinch! I am an out of town college student and have needed to take my truck (old chevy w/240k+ Miles) in a couple times for a muffler and tailpipe that has rusted out or broke from age. Every time Jason gives me a very reasonable quote, excellent customer service and no bs. As someone who is from out of town I always know I can get reliable service and great quotes from these guys. I cannot recommend their service more!
Jason and his crew are top notch !! Theyve always done a great job on our vehicles ! Their prices are excellent, and they do quick quality work ! Id strongly recommend them for all the services they offer !
THE BEST, hands down!
He always does good work at a reasonable price.
Very friendly and personable ! They were quick to schedule and it was ready when they said it would be and very reasonable, in fact it was less than what I was quoted ! Wouldnt go any other place ! Thank you Guaranteed Muffler !
Good old fashion service with honest values...Thanks again Jason!!
This place is the greatest! Honest mechanics, sounds like an oxymoron but is true. Doesnt try to sell you things you dont need, but will let you know when things need fixing. Wonderful place, I tell everyone I know that if the car needs TLC this is the best place to go!
Jason is awesome. Super nice, knowledgable man.
People here are not friendly. Keep your judgments to yourself. Unprofessional. Would not spend my money here!!
Great place to work with! I needed a custom reroute on a 4” aftermarket exhaust to clear my ride leveling airbags. They did fantastic work in a short time frame for a fair and decent price. Highly recommend this place!
Ive had four different exhaust systems installed on four different vehicles here over the years. I have been very pleased with all of them. I keep coming back because of the great prices, awesome customer service, and above all else, the outstanding work they do! Highly, highly recommend taking your vehicle here!!!!
Great rates and very nice employees
I experienced a very friendly and professional service from Guaranteed Muffler. Excellent workmanship and very fast. Will definitely go back when I need these services again. Steve
Guaranteed Muffler always does a very good job and they wont rob you blind. I have not taken my current vehicle there but I have taken previous vehicles there for service and was amazed at how low of a cost it was, for good quality work. They are at least worth checking out.
I bought an old Chevy Silverado and the fuel pump went out about a month ago while driving down the road. I was stranded and know very few people in town. I happened to call the nearest shop, and boy did I luck out! Jason towed my truck the few blocks to Guaranteed Muffler and had the fuel pump fixed by close of business that day. He even gave me a ride home while I waited. Most recently, the truck was acting funny again and Jason was adamant about taking another look at it. Luckily, everything checked out fine, for now. But I know if something goes wrong in the future Ill be taking it back to Guaranteed Muffler for their excellent care!
The only place in Helena that has changed my oil in the last 23 yrs
Jason and the crew will set you right at a great price
Great people and great work with a price tag that works. Its not often you find a fair price with quality work, here you will.
No nonsense, no BS... these guys are top-notch! They will tell you straight and treat you right. Weak-kneed and easily offended may want to go somewhere else because youre not coddled with platitudes.
Always honest and helpful. Great rates. I have learned to just go there first.
I live outside of Townsend, and had an appointment in Helena. En route to Helena I had an issue with my exhaust, my car sounded sick, almost like a Volkswagen, only worse. I took it to Jason at Guaranteed Muffler, he waited on the customers that were there to pick up completed repairs, pulled my car in the shop, pin pointed the issue, did a quick fix,had me out the door and on my way in no time at all. I will Definitely be going back for any further work I need in the future. Thank You, Guaranteed Muffler, and Crew!
Have always used guaranteed Muffler. When I was a service advisor at GM I sent all our exhaust work there. They are friendly and fairly priced too.
Very knowledgeable with what they do I will keep going back to them
Jason and his team at Guaranteed Muffler are the best. I waited until my axle was about to snap to take my car in for repair. Jason had me in and out in the same afternoon. He did not have to be so efficient as he had told me months prior that the repair needed to be completed. Couldnt be more happy with the repair and his excellent service. If you want honesty and good service, go see Jason.
Jason is a great guy! Always does awesome work and is very trustworthy. Takes great care of the people who go there and has an awesome, hardworking team supporting him.
Jason is one of the friendliest guys youll meet with a sense of humor to go with it. From exhaust leaks to full replacements hes your go to guy in Helena.
Single women, this is a shop you can trust!! After my car engine light turned on, I got panicked. These guys checked my car over and assured me there were no real problems with my vehicle. It would have been very easy to be dishonest with me as I am accustom to encountering with mechanics out east. Just by talking to them, you quickly get a feel for their integrity and care! Thanks you guys!!
Awesome place been there for two of my vechicles done in timely fashion and great customer service highly recommend
Got me in same day 100’s of dollars lower than other estimates I got in town and I forgot to go to the bank to get the other amount it costed and he trusted me and didn’t want me to drive to the bank that day because the conditions out and told me to just pay him tomorrow! Crazy only person in this town that still has trust for people! Brought him the rest of the money next day as soon as I woke up, also he let me watch everything they were doing and let me make the choices!⭐️⭐️⭐️⭐️⭐️
Very helpful and will do your mufflers right.
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.
No nonsense. Fast, efficient repairs. Cannot go wrong with these guys.
Absolutely the only place I would take my exhaust work and any mechanical work I need done.
Called to make an appt to get new exhaust tips put on. They were able to get me in 30 minutes after I called and were very fast and did an exceptional job.
Have taken a few different vehicles for repairs. Have always been pleased with the work theyve done and the price theyve charged.
Jason is the greatest!! Thanks again!
The staff was amazing, and the service is extremely reasonably priced, would definitely recommend!
Best value in Helena to get your truck running and sounding its best
The owner is on point with every customer, I have brought three cars to him and every time Jason and the rest of the crew is fast to get me in-out. Ive had mufflers and other odd welding jobs that he is always eager to help me with . . .
Jason Is great!!
Fast friendly service and reasonably priced.
Great work and very reasonable prices!
Jason always takes great care of our vehicles, he shoots straight and doesnt high pressure sell you on anything. Thanks Jason!

Jason is the man 3rd exhaust hes done for me
