Best exhaust guys in town. Fast and done right.
The did great Job very Professional and happy to recommend any person with car muffler issues. Price also very affordable. May God bless you keep up great work .
Sioux Muffler always does a great job at a fair price. Having equipped 4 daughters with school cars, I have called on them a number of times. Always honest, quick, and they do great work! Best place in town!
I was able to get an appointment for the next day. They got me in at the time of my appointment. Told me what I needed and how much it would be before repairing it. Work was quick and efficient! It was done in 30 minutes!
They have very reasonable prices and help me since I am from out of town. They also have great customer service I would recommend their service to anyone five stars
Excellent, fast, and friendly. Very knowledgeable and got my vehicle fixed in no time. Highly recommend Sioux muffler for any exhaust work you need
Denny does an excellent job. He is honest, reliable and efficient. He will not install items that are not needed! I highly recommend this business and will be returning for future business.
Wonderful place to take your car for muffler issues! Friendly, down to earth people! I cant thank them enough for helping me! They will be my go to place from now on. They book up fast so call and make a appointment. You wont be sorry!
Sioux Muffler was great! I dropped off my vehicle, but within a 15 mins they had already called me to tell me it was done and within an hour or less it was done. Highly pleased with speedy and friendly service.
I highly recommend Sioux Muffler! Denny was able to give me an accurate diagnosis and rough estimate over the phone. I made an appointment and my vehicle was pulled in at the appointment time. The issue was 2 of the 3 potential diagnosis as Denny had said, based off the info I gave. The work was high quality, done quickly and the price was very fair. Ill be going to back to Sioux Muffler with my summer vehicle to have a full exhaust system installed this spring! Thank you, Denny & Sioux Muffler!
Great prices, fast service.
Very fast and efficient with good prices.
Great people. Very fair and honest. Traveling through Souix City and had a catalyst converter stopped up so bad my truck almost wouldnt run. They worked me in and diagnosed it. Called to let me know what it was and had it repaired all in a couple hours. Great price too. Highly recommended!
Very good service and fast good prices will go back when needed
Very nice people he explained everything that he was going to do and the price
None better. Custom work is a great value.
Always do excellent work, got in and done in 45 min. Had duals done on avalanch, look and sound great
I live in MN and I took my car to another place there and they charge me 35bucks just to lift up my car and estimated that it will cost 1300 to fix my exhaust. I called Sioux Muffler and they said theyll take as look at it no charge. They ended up fixing it for 145. Saved me sooooo much money and my car no longer sound like its dying! Very good people here
Edgar was incredibly fast. I was in and out in about 20 minutes. Definitely recommend. Denny was very courteous and friendly as well. Fast fixes and good prices. What more could you ask for? Dont forget to tip the boys some beer money!
If you are looking at this and wondering how they have almost a perfect 5 star review, it is because they deserve it. Kind and courteous, but with a straight to the issue approach.My exhaust system was broken in 3 different spots. Hanging to the ground broken. And they got me in and out in less than an hour. (With appointment)If you have an exhaust issue, this is the place you need to go. Hands down.
They were GREAT. Very friendly staff.
Most wonderful and honest people, they’ll do the job just right and not trying to rip you off on the way!!! 100% recommended!!!
Very professional. Ive taken 2 classic cars there for a complete exhaust system and both times I had a Great experience. This guy has talent.
The staff was nice got me in and out quick .
Always friendly and great service and price
I never question the advice and cost. I have been having mufflers installed here all my life and they treat you with respect. If only I could find a mechanic I trusted as much.
These guys are nice.
I went very early for my appointment and there was a cancellation so I was done before lunch time. The problem was an easy fix.
They tell you whats wrong, and quick out the door
Very helpful! Reasonable price!
I wish these guys did more than exhaust systems, they are just awesome! Actually, though, I am glad they do only exhaust - and they are the absolute best! They are honest, fast, reasonably priced and do it right every time. I recommend this place to everyone I know!
They did what I asked and got both vehicles in and was done before expected
Awesome job, quality work and friendly people
Super pleased!! Took my car since it was making a seriously bad noise and since this place had great reviews I went for it. No regrets!! Fast, great value and excellent service!!!
After taking a very rough dirt road one night and tearing up the bottom of our car (at least, we thought) We took our car to Sioux Muffler thinking we needed a whole new exhaust system. We were shocked when we were told that it wasnt necessary and they could fix it for next to nothing. They could have charged us hundreds of dollars but didnt. They are the most honest business I have ever delt with and they will always have my business!
Been going there since I put duals with glass packs on my 65 galaxy. Always a quick, cheap, & professional job.
Awesome guys, awesome work, honest, affordable.
Denny is a very nice and honest owner.
Excellent service, and good price !!!👍👍
Got my 2016 ram 1500 muffler deleted and couldnt be more excited about the sound! Definitely encourage getting it done. Sioux muffler was extremely quick and super helpful! They definitely deserve a 10 star rating!⭐⭐⭐⭐⭐⭐⭐⭐⭐⭐
Very please. Honest people and got work done in one day. I recommend to everyone
I had some repair work done on my truck. They were very helpful, only took about 1/2 hour and was very affordable. I highly recommend Sioux Muffler and will be a return customer in the future. Great people to do business with!
Ive read some of the other reviews and and the only word I can come up with is PROFESSIONAL, You felt welcome when you walk in to the time you left. Outstanding work. I am very pleased.
Very helpful and knowledgeable staff.
Knowledgeable and friendly staff. Took care of my problem very fast.
I had both of my vehicles exhaust system done here. Three of four years ago. They are still great. They did exactly what I asked for.
Great place!! And great prices!!
VERY DECENT GUY HERE. HAVE USED MANY TIMES OVER THE YEARS. YOU WONT GO WRONG DEALING WITH THIS PLACE !!
Appreciate the fast fix. These guys are honest and didnt try to say I needed anything more than what I needed. I highly recommend and if I ever have any exhaust issues this is the place I would bring my vehicle back to.
Best of the best muffler shop
Best muffler shop in town!!
The very best and honest muffler shop in Sioux City.
They allways are nice here and do a very good job.
Believe the hype. Honest, considerate, and affordable. Not sure you can ask for anything else.
Best place in Sioux City to get exhaust work done, Ive had them work on three cars now. The staff is very professional, and helping. Ive had them do custom work on my cars, and the owner (I think its Dennis) would ask me what Im going for, then give me some options. Basically he doesnt just try to sell ya something you didnt want. On my last car(which is really clean) I forgot to line my trunk with towels for the old mufflers, they lined it with cardboard, which I just thought was nice, not too many places do little things like this anymore.
Awesome great and fast service. Owner told me it will be 20min, my appointment was 8am. 8:11am i drove off. Very reasonable price also, i recommend them highly.
In and out very quickly, service was excellent and staff was very friendly. I cant even tell my car is running now its so quiet now!
Excellent customer service very honest and helpful! I didn’t have a muffler problem but a starter problem and they steered me in the right direction to getting my problem fixed! Thank you!
Closed for Labor Day. Otherwise, each time Ive been there, its been great.
Amazing service! easily best experience I have had in town with any vehicle repair. Will recommend every time!
Dennis and his wife run a great shop, very nice and great service. You can tell Dennis is a straight shooter, he will give you his opinion and advice and never try to force you into anything. The prices are very good and he has now done 3 of my cars. Id recommend him to anyone.
They offered me options for better value and quick too!
Honest people, great work, fast service and fair price. Highly recommend.
Excellent service. They were able to do my job (cat back) in under 30 minutes and a good price. Another place I went wanted more than double what I got charged here. If you need muffler service done to your vehicle, I cant recommend this place enough.
Best exhaust work in town. People there are great, service is grade A. They will do all my work.
Denny and his staff are great, always done right the first time.
I would like to thank Dennis and his wife for the hospitality they showed towards me while i was there waiting for my muffler to be put on. They have a very nice shop and are fair. No upsale or hidden costs. Got me right in and was gone in less than a half hour. Their son and Edgar are the two boys working on your car and they do a great job. I highly recommend this place if you need any exhaust work done. Thank you for the service today!!JasonMN
Absolutely loved the service. Great!
Excellent service at a very reasonable price. Absolute perfection.
I called yesterday to Sioux Muffler after my car was in the shop at Toyota. Toyota told me that it would cost $1450 to replace my muffler. Sioux Muffler was able to look at it this morning and got me in on the spot, and I still made it to work by 8:30am. And their price was right. Only $104.95 to fix what needed to be fixed!!! Go to Sioux Muffler for anything you need on your exhaust! Their customer service is wonderful as well!!
Really friendly and knowledgeable staff at this business location. Service is fast and well done!!
They are amazing. Extremely helpful they dont try and sell you things you dont need. They go the extra mile to make sure everything is done right. Will go to them again.
Help me out when I was in a hurry close to home nice people quick-service I was in and out
Good people, great prices, fast work
Best place to go for all your exhaust system needs! Very reasonably priced and friendly staff.
No other place to go in town! Denny will always take care of you!
Very professional. We were driving a car that needed a muffler. We were driving from So Dakota to California. The owner found a muffler had it shipped same day from Nebraska and had it installed in under 30 minutes . Thank you for getting us back on our way home and a much quieter ride.
Went to get my Duramax straight pipped and wanted a certain brand of exhaust.. Told me it would be a while before he could get it in. Straight shooter, didnt try and force another brand on me to get it done quicker, 2 weeks pass and he personally call me and said he had my exhaust, dropped my truck off at 9am and he told me he would have it done in a day because other cars were ahead of me (not a problem for me), called me at 10:30am that same day and they were already done! Highly recommend Sioux Muffler! Fair prices, crazy fast and excellent costumer service!!
Fast service, great prices, excellent work.
Fast service! Good advice! No pressure, they didnt try to sell me something I didnt t need. Im from Texas and they treated me like a local. :)
I just had my vehicles muffler replaced the other day.Was able to go in without appointment and work was done within two hours.They gave me choices on estimated costs based on my options.Will definitely come back and recommend to friends and family.Thank you again!
