My car was making extremely loud noises after leaving my driveway because something underneath the car was damaged. Every time I'd start the car and accelerate it, it was so loud that I thought I might need to wear ear protection as if I was at a shooting range. I don't know much about cars so I was worried, but after coming to Excalibur Muffler, all my worries disappeared. They were very professional and helpful. They quickly spotted what the issue was and fixed everything so I was in and out within 15 minutes. Now the car is quieter than it was before the problem! They do a great job and I highly recommend anyone check them out if you're having mechanical issues with your car. The value of the service is top tier, and it only cost $75 for me to get the service that I needed done for my particular issue. I'll definitely be back again in the future if I need help for my car. read more

I purchased a Flowmaster Outlaw Exhaust System. They did an outstanding and fast install on the job, and their pricing is extremely reasonable. I felt like I underpaid for the work done. This was done on a 2025 Ram 1500 SST SO with the twin turbo. The truck sounds as good as a HEMI if you're looking for the aggressive sound. I will absolutely be a returning customer here. read more

I got a Muffler Delete Axle-Back Exhaust and did the installation through American Muscle which selected Excalibur Muffler as my installation shop. They did quick and clean work installing the parts and I'm extremely happy with the finished result! I don't do much exhaust work on my car but I'd 100% return here if I do any in the future. read more

First class work! I asked Darren to build a custom exhaust for my '65 Chevy C10 pickup. Pretty tight fit. He totally nailed it. The exhaust is as solid as the frame. Beautiful work. Fantastic price. I'd highly recommend Excalibur Muffler.l read more

See all

The guys ar the shop did an excellent job when coming to installing my new catback. Definitely the place to go when trying to save money but as well as getting great service! read more

These guys were awesome!! Very knowledgeable, fast excellent service. I had my cat converter stolen out of my 2008 Prius and they replaced it for me and reinstalled the oxygen sensor. Very fair pricing! I also asked for an oil and filter change. Simple enough, but other shops always overfill my tank. These guys were excellent! Perfect oil change, fast, only charged $20 for labor since I had my own filter and oil. Would recommend to anyone! read more

Absolutely not enough good things to say about Excalibur muffler...definitely one of the few remaining auto repair shops that is honest and reliable. Great experience, saved me both in a better price for the work that needed to be done and did not try to sell me the parts that were not needed like the first shop I was at. Also, they knew I was in a crunch without the car so they surprised me by getting it done a day early! read more

I would not use them. Not trustworthy. Overcharges! First of all this place is not close to me at all. It's about a 40 minute drive one way from my house, some I'm making multiple out of the way trips to attempt to complete these repairs. There was so much wasted time! Then I additionally end up dealing with the difficulty of getting overcharged... let me explain. Darrel is the owner and he attempted to grossly overcharge me. Quotes $1100 to cut off both of my catalytic converters and then weld on aftermarket ones, and was given a Quote for $1800 for bolt on with an initial $500 deposit. I drive a 2008 sedan with over 200k miles, and the way my car is setup you would pretty much have to unbolt the pipes to get to them to weld anyways. I also don't know why bolt on was quoted so much higher but whatever. So I agreed to the $1800 quote bolt on option for brand new parts and services. I pay the $500 deposit but need to come back in a few days so the aftermarket parts from "Eastern" can arrive. A few days later I return so that my vehicle can get repaired. I brought the car in first thing in the morning and they had it in the rack from 8:30am and called me that it was completed about 1:30pm that day. So I return to pick up the car and now I'm told that the total will be $1962! I ask you quoted me $1,800 (mind you that is already super high) and Darrel told me it was for taxes?! There was no itemized records or receipt for parts and labor and honestly I have no idea how he got to that number. He then proceeds to charge my credit card the full $1962, not even taking into account the original deposit amount. He then states that he "messed up" attempts to void it in his system and then reruns the about for $1462. My credit card company catches the multiple transaction and declines the attempt. Now I'm immediately on the phone with. Credit Card services who tell me that they have a $1962 pending transaction on my account. They are not able to cancel the pending, but take note of the dispute. They advise me NOT to attempt to use another card and that I will have to wait to see if the charge goes through or if the merchants attempt to void is actually valid. At this point, If the original charge goes through. with all things considered I've grossly overpaid by $500 from the original $1800 quote plus his second attempt to charge me $1462 (Thank God the CC company caught things). I end up getting my keys from the shop and leaving. After the military I got into analyst work, so I ran the numbers and things just didn't make sense. I ended up disputing the $1962 charge on my card so that I wasn't out the overcharge cost. At the same time Darrel called me multiple times and texted me asking about the payment. I could have easily just never contacted them again, but being a person of integrity I agreed to the original $1800 quote and intended to honor it (even if I thought that in itself was a high price); however I would NOT be giving this shop my credit card information again! Nor would I write a personal check that has a bank account number and routing number. I didn't want to pay in cash, because then I would have no proof on my account that there was payment for the services. I ended up going to my bank and getting a cashiers check for the muffler shop so that I could make good on my word, have proof, get the owner to stop calling and texting me constantly, and be done with them. I drove the 40 minutes back to the shop, he didn't even recognize me when I walked in. I said I wanted to settle the payment issue because I'm a person of my word and gave the check to Darrel in person and left. I know this is a long story, but I hope it helps inform someone else looking for muffler, catalytic converter, or exhaust services to think twice. This was a hassle and would not recommend this shop to anyone. They are not honest to their word and I believe take advantage of people. read more

Very accommodating considering it was mid afternoon on a Saturday when I called for help. They took me in and had my vehicle repaired within 1 hour. Highly recommended for exhaust system repair. read more

Traveling through town and my Old 1990 F150 Truck catalytic converters were getting annoyingly loud from all the rattling. Pulled up to Excalibur Muffler shop talked to Darren and asked if he can fix my muffler before i continued my travel to Austin Texas. Darren explained to me the fix and quoted me a fair price. Darren pulled my truck right in and started the fix right away. He even recommend a good place to wait and grab something to eat while he fixed my muffler. A little over an hour later, he's done with my truck and I'm back on the road. Excellent customer service! read more
