Quick and friendly place. I called about deleting my resonators off my 2020 bmw m550. I was assured that they could do it and they did a great job. Was in and out in one hour and I could not be happier with the staff and price. Would highly recommend.

Always great pricing and quick service. 4 hours have changed. Their only open Monday Tuesday Wednesday thursday, close Friday Saturday and Sunday. They have been in business for a long long time Mildred deserves little time off.

I strongly implore not bother going anywhere else but Don’s - they’re the best in town, and every customer there will agree. They made quick work of rectifying an absolutely atrocious “custom” job by a major chain on my V. The quality of fabrication/work is superb and their knowledge and openness is second to none.

Midas, Car-X, meineke all turned me away for a challenging over the axle pipe on my very rare car. I was told to come in and the would look at it. Within ten minutes they had Inspected my car and gave me a price fire EXACTLY what I had requested. Everyone else told me no, the young lady at the counter was on her shop game for sure. 100% I'm bringing all of my exhaust work to this place. You're making a bad decision going anywhere else . A special thanks to all the employees, I'm sorry I didn't catch all your names but thank you everyone

They were friendly, fast, and affordable. I needed to get a leak in my catalytic converter fixed fast so I could pass my safety inspection and they had me in and out the same day I called. All the great reviews are well deserved.

Top notch exhaust work. I have used them on 3 vehicles so far. 2003 Honda CRV catalytic converter, 1990 Toyota LiteAce full exhaust, and a 2014 Jeep Cherokee exhaust repair. Ms Mildred was fair and I will more than likely be using Don’s Muffler Clinic in the future.

I used these guys for my exhaust on my Cadillac CTS V. They installed a custom exhaust from x pipe to mufflers. They nailed it its now months later and no problems. They aligned the chrome tips perfectly. Good price A+

Took my car in today with my husband after someone cut out our catalytic converter Friday night, such a bummer! All day Saturday we called anywhere that was open to get quotes with everyone telling us $1,200+ For parts not including labor. We googled Dons Monday morning and read all the amazing reviews so brought our car straight in. Thank Jesus we came here because the service was AWESOME. Wait time for what we had done was incredible, and the price OMG!!! Here saved me so much money and the work was quality. For what they are doing their turn around times are incredible, you can tell the lady running this shop moves with purpose & cares her customers are getting the best price. I’m hoping we don’t have this problem again lol but if we ever need exhaust work again this is 1000% where we will be bringing our car. If you need work done GO TO DONS. Don’t question it, don’t call anywhere else, bring your car here because you will NOT regret it. Thank you guys again for the awesome work getting my car out of GoKart mode and back to smooth driving!

Fast service and friendly staff. I came in needing some work done and was out of there in under an hour. Price seemed fair although I don't get muffler work done very often.

This shop came highly recommended and was easy to see why, staff was very friendly, welcoming and knowledgeable!! This shop was able to do what other shops said couldn’t be done or didn’t wanna do!! Welded up a muffler for me and added tips exactly how I wanted and had me in an out in about 30 mins or less!!! Exceptional service will definitely be recommending and be back in the future!!!

Before going to Don's, I took my car to 2 other "exhaust" shops for a simple axle back exhaust install (basically just mufflers) but got turned away because it used clamp connectors. You would think an exhaust shop could handle cutting and clamping pipes. The exhaust was name brand (Corsa) and specific to my make and model vehicle, so it's not like it wasn't a direct fit. I came across Don's, gave them a call, and explained what I needed. They said no problem, just bring it in. They had me in and out within an hour, and even welded it for me instead of using the clamps! Top notch service, people, and work quality. And at an unbeatable price. I highly recommend.

A no frills auto repair shop. They only do muffler repairs. No appointments. No planning ahead. I arrived at 12:30 PM. There were several people standing around. One guy told me I needed to go inside and fill out "the paperwork". After I filled out "the paperwork", which was a description of my car, my address, phone number and a simple description of the problem I gave the owner my keys. I asked how much an estimate would cost. She told me "Nothing." At about 1:30PM she told me it would be $285 plus tax. Which was $200 cheaper than an estimate I had already gotten. At 1:57 I was leaving with my car repaired. For less than $300... Comes with a one year warranty. Check them out!!

Hi this is Sandra with the Blue Toyota Corolla, I came today about 1pm. I was immediately waited on I thought I needed a muffler but after them looking at my car I didn’t need one anyway. I truly appreciate them being honest about the muffler because when you are a woman a lot of mechanics tend to take advantage of us. The ladies and guys were very friendly and helpful. I truly appreciate your honesty. I will always recommend others to your shop and if I ever need a muffler, I will definitely use your service. No charge for anything. Sincerely Sandra R

I came here at 10 am on a Tuesday by a recommendation. I only waited about 10 minutes until they pulled my car in to take a look. The price they quoted was what I expected, so I gave the go-ahead. They had my exhaust fixed and back on the road in an hour. Excellent customer service, excellent location, and very fair prices. I would highly recommend getting any exhaust work done here.
