Hex did a great job replacing my catalytic converter on my 2016 Ford F-350 Super Duty! He also, replaced my two downstream oxygen sensors. As a result, I passed smog right next door at Sun Smog! With a month, I replaced my upstream sensors myself. All codes cleared! Thanks Hex!!! read more

This is not your ordinary, dime a dozen muffler shop. And the owner isn't just a guy who can weld and turn a wrench. The type of work he turns out earns him the right to be labeled a true Craftsman. Every job he does is thought from start to finish. If he finds a better way in the process, even if it means more time to do he does it and continues the job his way until done. He doesn't look for recognition or a pat on the back from his customers. But those who know him well knows that when he hands over the keys he alone has pride of a job well done. It's personal for him. Every time. And if you ever want to see this guy light up, tell him what you are looking for in how you want your car to look or sound. Then tell him to surprise you and do it the way he wants to do it. Expect the unexpected then. I personally have had him take care of my exhaust system needs for many years now. Most memorable vehicles he done for me were the Toyota Supra, Nissan 300z, Corvette and Nissan GTR. read more

Hector is a master at his craft and has operated his shop for almost two decades. He's friendly, focused and meticulous. Always available when I called to work through our schedules and returned messages promptly. He even offered to come in on a Sunday to do the job! Up front with pricing and multiple payment options were offered to adjust the final price. Best of all, his work was flawless and my car sounds like new again! Old pipe and supports were cut out, new pipe molded on the spot, and then mounted/welded back on (with the original supports welded on too) in under 2 hours, beating his own estimate! I strongly recommend Hex Mufflers for all of your exhaust needs! Five stars! read more

Great customer service, I brought down my bmw 325i showed him a little clip of what I wanted and he automatically knew what needed to be done and the car turned out well. Prices were fair, work was amazing. He's really passionate about what he does which gives in my opinion the buyer a sense of relief knowing your car is in good hands. read more

I've been to Hex Mufflers twice for two different vehicles. Both times, Hector did an excellent job. I am not very familiar with exhaust systems so I explained to Hector what I wanted, and he delivered! Both times, he left my car and truck, sounding great. Completely re-did my exhaust systems. Not because it needed it, but because I wanted something different... I also noticed improvements on performance. Hector definitely knows his stuff. He's also a good and honest guy. Prices are very fair, especially for the top level work that he does. After the recent work on my new truck, a friend of mine brought his truck to Hector and is also very happy with the work he did. I highly recommend this place! read more

Call to get a price for a basic muffler on a work van and they said they don't give prices on the phone so they'd rather have people drive around town all day finding out pricing. Very simple question how much is one basic muffler on a work van and couldn't even get a basic price. Call three other shops gave me a price on the phone right away. I have a business myself and we give prices on the phone all day long to save people a lot of time and time is money. read more

I highly recommend this place. Hex is really honest and professional guy. He does custom works. I brought my scion tc to install cat-back exhaust. I took little while but i think it's pretty short time to modify everything. Also he offers really fair price. read more

I came to Hex after the catalytic converter was stolen out of my 2004 Honda Odyssey. He already had good reviews on Yelp so that helped me make my decision to come here and I must say, his reviews are well deserved. When you pull into the driveway, you see a lot of custom cars so I wasn't sure if Hex worked on "regular" vehicles -- but he does. The fact that he does custom work told me right off the bat the this guy knows his stuff (welding, bending pipe, etc.). Hex is a personable guy and he told me straight up what I should do as well as my options. I really appreciated the fact that he didn't try to push me into doing whatever would make him the most money. The work was completed quickly and for a very fair price. If you need any exhaust work done on your car, I highly recommend Hex. read more

Catalytic converter stolen from my Honda Element. Hector at Hex Muffler was fantastic. Very informative and just a great guy. Awesome custom work at great prices. Great customer service. Will go nowhere else for my business. Thanks Hex!!!!! read more

Very good prices and quality work I highly recommend. Went to a different shop previously and their work was very bad compared to here.

I was leaving work one evening in my Ford Explorer, and somehow my SUV was sounding like a motorcycle. I learned I had a catalytic converter stolen, and called a few places for quotes. Hector answered all my questions over the phone, and encouraged me to come in for a quote. I did, and Hector quoted me a fair price for the work, and did an excellent job of replacing the stolen catalytic converter with an aftermarket one. He replaced the upstream o2 sensor as well, and helped me to troubleshoot a check engine light problem. He encouraged me to source the remaining parts so he could install them at a low rate. Thanks Hector! read more

Hex Mufflers is the best! I needed some work on my exhaust so I made a quick search on Yelp and I found Hex. I called Hector and explained what was happening with my vehicle. He asked me to bring it in and he'd check it out. I visited him while on lunch. He connected the code scanner to my car and explained to me the problem in great detail. Needless to say he was very professional and simple in his explanation. I do have to note that his appearance is a little misleading, he's actually a very nice, professional, trustworthy and respectful person. He gave me a very competitive rate and even replace my upper and lower stream sensors at no charge! He advised me to buy the sensors myself to help me save some money. My experience with Hex was terrific and I would recommend anyone to go talk to Hector for their muffler needs, he really is great! read more
