Got a new cat for my truck - quick service - passed smog afterwards easily - and a good value. I've never had a cat replaced in my life ever before. But my truck barely passed the last 5 times over the last ten years. I would nervously get it done each time and it would pass within one or five points each time for the HC. I would heat it up really hot and rev the engine at 3k rpm while waiting for the smog tech to get ready. Done with those days passes now all almost zeros. I've got one more old Chevy that is my age - and probably needs to get done also. You've probably only ever heard the price to replace the cats on a Prius - but I think most cars are just a small fraction of that price. Mine was a simple one cat system. If you do have a Prius come here. They build cages that have adapted to the evolution of cat thieves. As the thieves up their game so do these guys. read more

These are the kind of guys you want working on your car. When you walk in, you'll immediately notice the good vibes and rad artwork all around. DTM installed an aftermarket AWE exhaust system for me and they are now my new go-to exhaust shop. Skip is an artist and a craftsman. I'd go back to him any time for exhaust work. Care was taken to make sure there was no preload or tension in my system as it was clamped down, and the quad tips were perfectly aligned. While he knocked out my install, the owner, Jack, took care of another customer who had a quad tip alignment issue from another shop's install. It was perfected in under an hour. Great work, efficient and customer service. Five stars! read more

Had an excellent experience today at Downtown Muffler Shop in Hayward. Jack is incredibly genuine, personable, and easy to connect with--no scripted customer service here, just real professionalism and kindness. When I shared a bit about my son's recent challenges, Jack went above and beyond in a way that truly moved me. Skip worked on my son's Lexus CT200h muffler quickly, and the quality was outstanding. This is a business that truly values people--highly recommend! read more

Came here to get a cat replaced on my '85 911. Fast and professional. And that was on a christmas eve. Incredible!

bait and switch with pricing. someone stole my Cadillac converter from my Honda element. I found this location that said they had them in stock and could install a new one. called me an hr later giving me a quote of $500 parts and install when I arrived to pick my car the older white guy gave me my bill and said $700.. where did the extra $200 come from and of course I needed the work done so I just paid and left. don't do business with this owner he's shady and tries to get more outa you when you arrive. read more

My car failed smog test. I was recommended this location as I needed assistance with exhaust system. The customer service did not answer my call. However, my call was returned within one business day. The staff was professional and agreed to look over car the next morning. At the time of the appointment, the mechanic looked over the car and reset my system to address the problem. They did not charge me for the quick service. The mechanic also reminded me that it's against the law to pay for a failed smog test, which I did not know. Super helpful and kind. Highly recommend. read more

I found the best muffler shop in town! It's a little intimidating to go to a shop sometimes as a lady, or even just someone who is not as familiar with their vehicle as maybe they should be. I always worry about getting "gauged" . Let me tell you , Skip and Jack were two of the most professional, helpful, and informative guys I have ever had look at my lil go kart. I super appreciate honesty, especially when it comes to forking out my dough, so i wanted to shout them out for being awesome and a fair value! Thank you both and I will be sure to come back soon and send you anyone that asks! read more

Jack & Skip are awesome, Previously came in for a Resonator Swap & Muffler delete on my 08' M-B CLK550 & sounded good for about a month lol, so I went back to them to install a megaphone in place of the resonator for more sound & it sounds so much better now! Very pleased with the work & will be bring all my cars here for a sound upgrade, read more

The amazing gentleman who owns this place as well as his outstanding employees that work here are doing the Lord's work, truly. Fantastic customer service, friendly, reliable, honest, compassionate, caring people. Yesterday I was driving by and stopped for a rough quote to repair a broken exhaust pipe, (I went over a steep speed bump, hitting and breaking a rusty piece of pipe out of my exhaust behind the flange under the cabin making it so droning loud) they gave me a rough estimate and said if I was able I could leave the car and they would take a look at it. However, I had a few things to do so he told me to go back in the morning. This morning, I got there when they opened and they had me pull in right away and got my car in the air, after originally saying it may take up to an hour depending on the severity, once they seen it they told me 20 min or so and they would have a new section in place. Fast forward and my car was off of the lift within 15 min!! with a new section of pipe, beautiful welds and a quiet idle! THE OWNER REFUSED TO LET ME PAY!!!!! As a gentleman in every sense of the word he made me a deal that I would take my Girlfriend out to a really nice breakfast as his treat and my payment!! I never brought this up once however I am disabled and not in the best spot financially so this was a blessing to me in a time where any help is taken to heart and it laid the foundation for an amazing day taking care of what I had to. P.S An amazing breakfast was had and I thank you again if you read this! You have made customers for life and will be my only muffler shop recommendation moving forward. I'm so glad I stopped and met you guys! read more

Great service. I called to see if there are any openings for a walk in. Brought my Type R in for a resonator delete. Took about 20-30 min and left happy. Also gave me a good price if I come back and get the 2nd one removed which I will be soon. Welding is decent I would recommend to check this place out if you need some work done read more

Wow !! This place is amazing with super friendly and knowledgeable staff. Friendliness was apparent just from the initial phone call. I called about getting my catalytic converter replaced for my Corolla SE 2003 and the staff member was friendly, courteous and wasn't pressuring me for a sale. He was easy going but still able to answer my questions, and we setup a drop off time. When I showed up I was greeted by Jack the owner and this guy is awesome. He gave me a rundown of what he had to look at and what else needed to be considered, that he would look through it all and let me know what he finds. And explain he did, Jack is so knowledgeable on this stuff he should be making entire exhaust systems for cars himself. It turns out we needed a catalytic converter plus the gasket needed to be changed, he did it all and the car runs great with no car engine light on anymore. What really impressed me was that he is a man of his word, he didn't try to up charge me in anything just what was needed and things I needed to consider in the future. He does what he says and says what he does. This is rare, and as I get older in life it's actually the most important thing to me when I do business with people. I totally recommend this place to anyone needing muffler or exhaust help. Thanks again Jack, you're a really stand up guy!! Awesome doing business with you!! read more

The owner was very honest and friendly. I went in to get my catalytic converter checked (I knew I had to possibly replace it) in May of this year and he was very thorough about the condition and the work that needed to be done. The quote itself was a fair price for what my Nissan needed and after the actual work was completed, the price he charged me was a few hundred less than that initial quote. I went back today because I saw my tailpipe was loose and shakes when I drive. After he inspected it, he noticed that it looked like it was hit underneath (I drive through Oakland a lot with many bad pot holes in the streets). He took it in and was able make it back steady and sturdy in less than an hour with no appointment. I recommend going here for exhaust issues and repairs. Great guy, works with you and does the job correctly and in decent time! read more

Samantha was the one to help me get in and out quick. Got my resonators welded on in less than 30 mins, and also thy straightened out my muffler tips for free. I gave them an extra $20 tip because of the hospitality! Great people and great customer service! I would recommend this place for anyone who needs some muffler work done! read more

They did me a solid, we're upfront and the price was real good. Would go back for catalytic converter issues again. Highly recommend!

Installed a straight pipe in Santa Barbara for my Audi s4 and the technician installed it wrong causing one of the pipes to be loose. I'm new to cars and modding so i decided to come here since the reviews were great. The owner was very nice and took me in for a walk in and immediately pointed out the issue with the pipes. I was able to have it resolved within 5 mins and my car sounds great again. Thank you so much I'll definitely be coming back! read more

Jack and his team are great. I had a issue with my catalytic converter for my old care and Jack took the time to work through all my options, when other shops would not even discuss it over the phone. NO smoke and mirrors, just straight up price and options. I recommend giving them a try, they know what they are talking about. read more

Wanted to say Thanks to Downtown Muffler for helping me getting my truck back to stock sound. The last month or so I have been messing with different muffler to make my car a little louder. Everything was good for a bit until I drive on the freeway 65mph plus and that little drone was getting on my nerves. Was planing to just buy a stock exhaust but everyone wanted $350 plus for one so I said nope. That was same price as a brand new one from the dealer. I appreciate how they broke it down for me what each muffler do and which one will make it quiet again. Everyone I called in a 30 miles radius. They keep saying oh go with this flowmaster or Magnaflow to make it quiet and in my I head I am like ok NO because it going to be the same shit I have right now but different sound and tone! read more

This is my first time doing business with this company. I was recommended to this location through Castro valley tire pros due to me having exhaust related issues with my truck. Upon drop off attempt they informed me they were going to need a couple of hours to get the work done I needed so if I had anything I needed to do I could go get it done as long as I dropped it off by 4:30PM. I got what I need to do done dropped off my truck for the second time. They told me they would need two hours and they could get it done by 2 PM. I said OK that's about the walk to my house and back so I'll be back in two hours Before I was able to start walking away the owner (Jack) asked me where I lived and he said oh, I'll just give you a ride. Let me grab my vehicle real quick and gave me a ride home with no up charge just out of pure courtesy. I'm still waiting to get a report, but I am thoroughly impressed with the it generosity and business ethics for this property. read more

Paid more than what I had expected, but at times, you have to pay the price to have it done right. Only time will tell, however, the hospitality, the professionalism, the care that I witnessed go into my ride made me feel like this was money well spent read more

I brought my 2018 Chevy ragtop Camaro, 2.0 VVT turbo, over to get some "rumble in the jungle," sounding exhaust. I didn't have too high expectations seeing the engine is a beefy 4-cyclinder, but boy was I pleasantly surprised! Jack (owner) and Skip were upfront with me that they had only done one other 4-cylinder (Mustang) for increasing the volume and my Chevy would be another chance to work on this unique use case. Something that was calming was Jack said if I wasn't satisfied they would weld back the muffler and just charge me $50.That was pretty harmless, so I Agee's to try it. They cut out the muffler and used two straight pipes (with three resonances), salvage and reused my nice exhaust tips. The result was what I had hoped for. The car started up and had a noticeable rumble and much nicer sounding, deeper tone both out and inside the car. Later I would hammer it and thoroughly enjoyed the new sportier sound. Keeping it real, it's not the throaty, super loud rumble like glass packs on a V8, but again, I love it! Price was a little more than I wanted to spend, but reasonable ($500). Skip and Jack are experts whom I trusted with my "White Knight!" Use these pros. You should be satisfied and pleased. read more

I first connected with Skip over the phone and I loved that he took initiative asking me to set an appointment and swing by for a free quote. Upon arriving I totally connected with Jack and he quoted me a super fair price for a full catback exhaust custom fabrication. His quote was nearly half of my quote up the street! I asked about his work. He didn't hesitate to take me over to a Cadillac DeVille that once belonged to Liz Taylor. He let me get underneath it and showed me some complex bends for a custom pipe install and some quality welding! He answered all of my questions patiently and I decided to give him my business! I literally stood there for 3 hours watching him put in work on my G! The shop owner himself Jack did the full install. He took incredible time and care and I was watching an artist at work as he stood gazing upon the install making fine tune adjustments before welding in place to make it proportional on both sides and aesthetically pleasing. He wouldn't even let me take pictures at the end until he wiped down the whole system to remove fingerprints... no joke!! I was supremely pleased with the quality and care put in by Jack. No bs. He gave me a super fair price with excellent attention to detail and I am proud to say this is my new exhaust shop and Downtown Muffler is where I will be sending all my future referrals! read more

Would definitely recommend coming here and will be back if I need exhaust work read more

My catalytic converter was stolen and I was referred to Downtown Muffler by Mangale Motors as Mangale doesn't do welding. I am pretty happy with the results. They charged me 3.5% to use my credit card saying that they couldn't afford to pay for my points on the credit card. I said that if I had known, I would have brought my checkbook. They then said that they don't take checks, but that I could have paid cash ($2400). They asked if it was okay to use the credit card and charge the 3.5% ($84). I replied that I didn't feel I had a choice. They estimated $1800, but there were extra charges for a flange kit and a resonator which was also taken. read more

My catalytic converter was stolen and as it turned out I had to replace it with an OEM. Toyota Nation in Hayward told me I wouldn't be able to get one for a couple of months. Downtown Muffler did some research and found one and ordered it for me from Oakland Toyota, who was very helpful. It's an experience I don't wish on anyone. $2100 later I have my car running again. Thank you Samantha and all the mechanics who took a very bad situation for me and showed kindness and respect. read more

Bait and Switch Warning! I went here by recommendation of a friend. I called in advance for a quote on, Flowmaster brand mufflers. They quoted and said, we have them come down. when I get there, the installer was putting my car on the rack, and I believe it was the owner that yelled over to him, "KNOCK IT OFF". Weird?!?! So come to find out when he's got my mufflers to install he did not have Flowmaster. He had "knock off" mufflers! In the industry, it is known to call the generic Flowmasters, "knock offs". This was the owners cute little way of trying to be sly and telling his installer to give me the cheap stuff "KNOCK IT OFF" (I.e., knockoffs). I told my friend that recommended me and I don't want to say his name, but this is greatly disappointing. He was embarrassed. This place is really shady. I hope people read this and take heed to the warning. This place is not honest. I would not trust them or recommend them. read more
