Not exhaust there for my daughter's car. It looks really good, and of course sounds really good. It wasn't really drivable so I'm brought in, a pipe was broken right at 1 of the cats. Gentleman that looked at my car was very nice, and wasn't pushing anything on me. Just gave recommendations. And I really like that. Nothing worse than being pressured into something.

This garage, this business is my preferred place to take my car car issues to. They are the best in the area because they have the knowledge of vehicle problems and they do do it with care. Depending on what your car issue is you get your money's worth. Shout to Nelson and the team. I recommend Mighty Muffler to anyone. It's a safe place, great facility right next to a Fire station. Feels much safer

My "Guy" and an old friend, Nelson who I've known for yrs, one of the most genuine business owners in the game. A welder/fabricator by trade, he's not just a counter man. Upfront with his plan, asks you and listens to your plan, BEFORE he starts the job. I knew he was a custom exhaust guy, but did not know they work on anything from high… horsepower cars, torque monster trucks, and anything in between. Some beautiful cars come thru his shop, you never know what you may see driving by. I'm well versed on the tools, but these guys are on another level.

Took my Porsche Cayenne Turbo S in to see if I can get a different sound out of the exhaust. I was trying to explain what I wanted and could not find the words. Nelson knew exactly what I was trying to say and was able to complete the job in 3hrs on short notice. I NEVER write reviews but I felt like this one was necessary because great work goes unnoticed and without a spotlight sometimes. And I didn't mention I live 45 minutes away!!!These guys deserve the attention for how good they are at communicating, delivering what they say and price! I highly recommend their shop. They took good care

Customer for life!! Had an exhaust leak on a 3yo Ram. Faulty bolt from factory. Common problem with Ram trucks. Dealership quoted me $1500, needed a new exhaust. Nelson (the owner) quoted me $100 new bolt kit. Got a new custom muffler instead with Mighty Muffler and they cured the exhaust leak. 2hr job and my truck finally sounds like a truck. Great job!!! Highly recommend!

I have a BMW 428X Drive and recently there was an issue with carbon canister and purge valve. After getting mad at local BMW dealer who attempted to rip me off, I brought my car to Mighty Muffler Auto Repair which is quite close to where I live. It turns out to be a good decision. The front desk (not sure if it's the owner) is a really nice person. He is knowledgeable, professional, and straightforward. He walked me through the options and got the job done on time, which made me feel customer experience was highly valued at his shop. Will definitely come again

I showed up on a Friday (from Philly) with no appointment because my exhaust was leaking; Nelson quickly took a look and gave me an estimate for much less than I expected. My daily driver is a 30 year old BMW and it was no issue at all, Nelson and his techs really know what they're doing. He made time the same day and less than 4 hours later he had welded up new pipes, hangers, and the magnaflow resonator i wanted to add to match my magnaflow high flow cat & muffler. I love the way my E30 sounds now! Phenomenal quality and great people at the shop, do not hesitate to come here for your exhaust

I came her for some exhaust work done and could not be happier. Nelson walked me through the whole process of what he would be doing to achieve the setup I wanted. Without having to ask during that time I was… told prices for each thing I wanted. They knocked it out in a few hours and for a great price. Very cool environment with a ton of food in the immediate area if you need to stick around. This is the only place I will go for exhaust work from here out !

Totally recommend! I called and made an appointment for my Audi A8L. Spoke with the owner. He is very friendly and very polite! He takes care of his business properly! Some people might say they are pricey.… Wrong! You better pay the right price for a job well done, instead of going cheap and then have to redo the entire job. I will attach pictures of the work. Thank you again for everything and congratulations for your shop!

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

Nelson and the team are great! I went there with a vision for a custom exhaust mod for my Kia Telluride. Not only did it involve a custom system, but fabrication was needed to cut the rear bumper. They did… everything within a few hours and I was a walk in! On top of that, the cost was more than reasonable! I highly recommend this shop!

I've never felt compelled to leave a yelp review before, but these guys have more than earned it. I have never had a bad experience here. They are always straightforward and honest and have never done me wrong. It's like they just want satisfied customers and not just dollars in their pockets....can you believe it? They are the best.

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

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!!

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!

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.

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!

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

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!
