extremely good shop..... I live in northern Virginia and have drove 247miles to have these gentleman work on my cars and they always hit the markat a very reasonable price. recently he did an entire exhaust on our minivsn in the time it took us to walk next door and eat lucnh at a dinner and come back... the only work theyve done for me is exhaust work but they are extremely good mechanics. read more

I went to mighty muffler they got me at 830 and 930 I was done car sounds amazing jr and his team are awesome. the young lady at the counter Julie us a true angel they are the best very good. 12 out of 10 in my book read more

If you need an auto mechanic for any reason, an oil change, brakes or whatever I would not hesitate to go to mighty muffler on Philadelphia Pike in Claymont. They are the nicest and most honest mechanics I've ever met. I called the other day and asked if they would look at my rear brakes, which wete making a squeaking noise when I back up in the morning. They brought my car in and evaluated it and told me that I have plenty of brake pad left. They said I don't need new brakes yet.. and then they did not charge me anything for the evaluation. It's just nice to know that there are really truly honest people out there who care about your business. My husband and I will go there anytime we need work done to our car with total confidence!! read more

First, NO I'm not a paid actor... just an overly satisfied customer who knows no better way to say thank you but to highlight the kind of work and people that are at Mighty Muffler. This is my second review, yes I'm back again because they deserve it. I'm simply blown away every time I come here. They far exceed my expectations. I was here a while back for my Porsche Cayenne Turbo S. Nelson took care of it and delivered exactly the sound and performance I was looking for. This time around I brought in my Maserati that already had a cool sound to it from the factory. Nelson gave it a look and listened to it and in under a minute knew what I wanted and how "we" would achieve it. The entire staff gets it. They are all knowledgeable and go beyond the call of duty in terms of making you feel comfortable while you wait. I wasn't paying attention as my head was in my laptop and my car was completed they parked it out front and started to rev it up. I turned around like man who's car is that...? It sounds amazing! I look out the window only to see my car and Nelson with a few of his employees smiling because they knew they hit it out the park with this one. They take pride in their work (as they should) and if I didn't properly show my emotion it was because I was at such a loss for words.. I think Nelson put it best as he handed me the keys... this thing is "Bad Ass Bro" I trust my car with these guys and you should too, my hope is that anyone reading this can tell my experiences here have been unbelievable and I've been enough places to know when there's one that stands alone in terms of customer service, job function, price, knowledge, and family atmosphere. Mighty Muffler has it all, and if I could get them to open a second shop near Blue Bell, PA that would do it for me. Guys thank you so much and once I get another car I'll be back again!

Mighty Muffler - Nelson taking the time to show and explain each tailpipe to me while my car is on the lift. The service here is just top notch! - Auto Repair Near Me - Claymont, Delaware

Very professional workers, very nice facility, nicest waiting room I've ever been in. However they are pretty expensive as far as exhaust shops go, you're better off going to Tiny shop to get work done. A simple exhaust job I had done cost twice the amount I was quoted at other shops. If you're getting custom exhaust modifications I feel like this would be a good spot to go though. read more

I not going to be the person who writes a horrible review bottom line . My suggestion is to go in there and first thing is ask for a tour and you will be very impressed the style is top notch makes you feel like your not in a automotive shop at all. And I would like to say thank you very much and God bless the whole crew ! read more

we have gone to Mighty Muffler for the past 10 years. I do not know what is going on or whats been going on. My husband took his truck for a regular oil change. the next day theres a hole in the panel and oil leak goin on. They said $900 to fix. Then my sister car was fine nothing wrong with it went in for a regular oil change next day their was an issue with steering and cant drive the car. They said it was going to be $1500!!! How do you go in for a regular oil change and come out and now theres issues with the car. Then I reccomended a friend and she took her car there and then the next day she had major issue with her car. Either the mechanic dont know what they doing or some shady shit goin on. Cant be a coincidence that 3 people brought their car in for a simpl oil change and then next day theres issuees. read more

2 stars for what appears to be decent work (i dont hear any rattling or anything but you cant see anything in this car since the converters are near the turbo). They like to play games however. I had a bad feeling about this place based on where the shop was located (claymonster, a place i havent visited by choice in over 8 years) but I took a buddys recommendation since they did great work on his RS7 and every other shop near me seemed to be booked out months. These guys are classic bait and switchers. You give details about the vehicle over the phone and request an estimate, and they give you one. Then you drop the car off super early on the day of the job and they call you 2 hours later saying oh, its too much work you will have to come pick it up and drop it back off again. Now I get it I have a specialty car (a V12 twin turbo mercedes) and I don't ever expect to cheap out on it. I have no issue paying good money for quality work but I will not overpay for services that are not rendered. The The kicker here is the guy at the front said "they work on these cars all the time" so I was confident they would give me an accurate quote and timeframe. So I come all the way back down 45 minutes drive, pick the car back up and take it home again and bring it back monday. Well guess what, they called me 12 hours later saying the car was all done (aka they finished it way quicker than expected) and still charged me the full ride. TLDR: Quoted me $1300 over the phone, ended up being over 2 grand at pickup..AND they got the job done even quicker than they would have the day that i dropped it off before! Oh..and to top it off, twice I requested they put the old cats back in the trunk and they didn't do it. I almost drove away without the parts luckily I looked. I'm sure they do this ALL the time. Guy at the front is gross and unkempt too. Typical delaware trash redneck. read more

Absolutely Awesome ! It's hard trusting a shop you haven't been to before with a brand new car but these guys are awesome ! I dropped of a 2021 Supra for a custom fabbed exhaust and hks lowering kit and they knocked it out of the park . Customer service - awesome , fair pricing- awesome, facility-awesome, craftsmanship- awesome . If you are looking for anything exhaust or automotive related definitely hit them up they will not disappoint. From the time I called to inquire about the jobs to when I picked the car up they were nothing but helpful and courteous. Yelp is currently displaying the wrong address it will take you to a different shop on the corner down the road about 7 lights . Their correct address is 3207 Philadelphia pike , Claymont De . Luckily the other shop directed me to their correct location . Want to personally thank everyone there for taking care of my pride and joy and taking her to the next level definitely will be a life time customer ! read more

Mighty Muffler - The front of the business - Auto Repair Near Me - Claymont, Delaware

Horrible customer service. Nelson is a hot head car wasn't fixed right the first time. Doesn't explain anything jus does it. No communication updates anything. Quick to take your money read more

True Business integrity, went in for an oil change and fluid top off and the work was done quickly and properly. Unfortunately an issue was found upon picking up the vehicle. The owner took responsibility without any argument and offered to resolve the issue with no additional charge. This business shows true integrity and customer service. I am very pleased with how they handle themselves and suggest anyone needing service to give Mighty Muffler a visit. read more

I have been using MM for more than two years to service my cars. They have never disappointed me! The people at MM are always ready to go the extra mile to get you back on the road safe, and at a reasonable price. Staff always friendly and you always know what you are paying for " before" the work is completed. No job is to small or too difficult for them to address. My suggestion to anyone that needs car repairs, take it to MIGHTY MUFFLER!! read more

Great family owned shop. Honest, dependable, reasonable, and knowledgeable. Couldn't ask for more.

Old school mechanics! The good guys! Can't say enough about their knowledge of every issue from oil changes to major repairs. The prices are fair and fully explained. They are happy to show you what they find if the job is bigger than expected. They are honest and trustworthy. Work is always done quickly and thoroughly. Because they were a newer shop I once mistakenly took my car to another local shop that damaged my car and they were upstanding enough to even go the extra step of dealing with that shop on getting my repair done. You cannot go wrong with these guys. Nelson is the owner and he will never steer you wrong. read more

Great service! Even better management, don't hesitate! Will definitely come back in the future!

I had Mighty Muffler install a dual MagnaFlow exhaust on my classic car. They did not rush this custom job. The team at Mighty Muffler cares about the quality of work they do. I would highly recommend them if you want an amazing exhaust sound. They also do a great job on other repairs as well. read more

Simply the best. Super friendly, reasonable, quick and efficient! What more could you ask for? Been going to them for over a year and will continue to! read more

If you need any work done on your vehicle, I HIGHLY recommend this location. Not only is everyone really friendly and helpful, but they are absolutely trustworthy!! A Toyota dealership told me I really needed my brake fluid and coolant flushed and replaced, that the fluid was dark and thick. I took it here and asked them to do the flushes, they took a look, called me and said the fluids were fine and didn't need to be changed. In an industry where it is easy for professionals to take advantage of you, these guys are looking out for you!! read more

Another perfect job done by Nelson and staff today. I first went to MM two years ago for custom exhaust and headers for my Charger Scat Pack, and have been a repeat customer since. Unlike many auto shops, MM does not sell you services you do not need or skimp on their materials. I know how to turn my car on, and then off. How the parts work in between is a mystery. But I feel confident every time I take one of our cars to MM for service that service will be 100% done properly and affordably and I will not have to worry about how things work. I knew this was a great shop when I had to return for follow up service due to a screw-up on my part (O2 sensors), but still Nelson did not charge me. These guys are the best! read more

Don't go to this establishment if you want great service at competitive prices. They will rip you off - overcharge you for mediocre work. Stopped in today to have the crack on my rims repaired and they just charged the max without even looking at the crack. Then, when it was completed it looked rushed and unfinished. Just unprofessional. Auto repair people will never shake their snake in the grass rep with shops like this! read more

Fantastic! The dealership I bought a truck from in Exton, PA, jerked Mighty Muffler around big time plus I had an inspection issue in MD. Mighty Muffler took care of it all. They remained professional, courteous and got the job done right despite obstacles. Thank you!! read more

This was my first service i got done to my Ralliart and i had an awesome experience. I came about an hour early and Nelson said "its no problem we'll take care of it". I was expecting to wait a couple hours since i came early so i went to the diner next door but by the time we finish eating in about 30-40 mins i came back and they told me it was done. Their pricing is awesome and their staff was also very helpful. I highly recommend them if you need any exhaust work! read more

Rotors and break pads were quoted competitively. They followed up timely on completion. Will be using them again in the future.

The only place I will take my car ever again no matter what's wrong with it. Seriously the nicest, fastest, most decent (and pretty well rounded, more than mufflers) mechanics you'll find anywhere. I have a 16 year old jeep, so stuff needs work every once in a while. I've never once second guessed anything they've told me that I needed and I've never once felt ripped off or taken advantage of. Thank you guys for taking such good care of our whole family and keeping us safe and on the road! read more

Today I had a great experience at a wonderful privately owned custom exhaust shop. Nelson and his crew are by far the best in the business. I took my 2013 Silverado in to have a Stainless Gibson cat back exhaust installed and welded on. I have been working on cars and trucks for as long as I can remember so IM very hesitant about anyone touching my cars. After long and careful consideration and research I decided that laying on my back in the driveway to install it myself was just not an option and besides I wanted it welded on not bolted on. Nelson you are the Effen MAN!! The tips are perfect and look so good and let me tell you these are the best welds I have ever seen. Sure just about any auto shop or backyard mechanic can install an exhaust system. But what they cant even come close to do is the perfection you get at Mighty Muffler from Nelson and his crew. The location of the dual exhaust tips is the most important part from an aesthetic stand point. If there not matched or are not at just the right location they look awful. Nelson has an eye for it. He is more then a mechanic he's an artist and has a customer for life. I'm telling everyone the service he provides is the very best. Thanks again you are the man and your crew is awesome too!!!! read more

I recently got my car serviced at Mighty Muffler and could not have had a better experience. As a woman, I usually have places try to up sell me and I did not experience that here. I received prompt and excellent service at a fair price. Nelson handled everything for me and made everything easy. I will definitely be bringing my car back! read more

I was on the I-95 N when a light came on on my dashboard indicating low tire pressure. I had no idea where I was but I my next exit was Marsh Rd so I pulled off in hopes of finding a gas station where I could investigate what had happened. I drove for about 5 minutes and came across Mighty Muffler; I pulled in and asked the gentleman working in the shop if I could use an airpump to fill my tire; it was visibly lower in air so we could immediately tell which one was deflating. He stopped what he was doing to help me, checked the tire pressure with a gauge, then saw a nail stuck in the tire and notified the owner, whose name is Nelson. He was SO FRIENDLY and he greeted me with a smile and ensured me they would take care of it quickly, and that it wouldn't cost much and he invited me to bring my children into the waiting room where they had a comfortable seating area. My son was sleeping but they had a couch and chairs where I could sit and hold him and my daughter and I parked ourselves in front of the TV and Nelson engaged with my five-year-old daughter inquiring what channel she'd like to watch; he flipped through until he found some cartoons for her. They took care of my tire within 30 minutes but as we waited I watched happy customers come in and out of the shop with smiles, so happy with their service, addressing the owner by name and chatting. I really never write reviews because I honestly rarely receive such excellence service and sincere kindness; as I drove away I thought about how grateful I was to find this auto shop. They seemed to really care about our safety as we had an hour drive home to Philadelphia; Thank you Mighty Muffler for making my day and getting myself and my children home safely! read more
