All Flow Muffler & Auto Repair

These guys are great and just saved me and my broken down car. I was picking up my dog from a nearby kennel when I discovered my car wouldn’t start and I had a heavily corroded battery terminal. They gave me a jump and proceeded to deal with my 6 year old battery and very corroded terminals. Out in less than an hour, which is amazing as the tow truck was quoted as an hour to an hour and a half out due to it being the first business day after a holiday weekend. Also, Teresa, is fantastic to burn the time with.

If you need anything done ro your car, I would highly recommend All Flow Muffler and Auto Care on Pacheco Blvd. I have lived in Martinez for 16 years, but thought this shop only did mufflers… boy was I wrong. In the past year or so, I’ve taken my car to him for various things, but never a muffler problem. This morning I took my car there because my ‘light out’ indicator appeared on my dash. Daniel is nice, friendly and professional, and he was able fixed it on the spot… and charged me very little. If I took it to Mercedes, I would have had to make an appointment, and they would have charged so much more. Now I can’t say he will do all fixes on the spot, but he is much quicker then anyplace I’ve tried in the past.
Try All Flow. I think you will be pleasantly surprised, and no I am not related to anyone there, and no, I am not being paid to write this.

These guys were great. knowledgeable, fast good price. We will definitely be back

Great service, fast turn around time and extremely reasonable quote.
I have an older vehicle that has never failed a smog check. Apparently it would not pass at the smog center due to exhaust leaks in the muffler. All Flow got me in, replaced my muffler and I passed smog. Thank you Danny and All Flow!

Excellent, excellent job and customer service. Got a new muffler for my 2012 Camaro, and was recommended to here. They got me in and out and their integrity is off the charts. Quoted me for parts at one price and found out the parts should have cost more but they stuck to their original quote, real stand up quality business, the type of business that makes a customer want to go back… muffler sounds amazing by the way. 5 stars

All flow is a good place to take your vehicle, I’ve had exhaust, brakes, head gaskets, and other things done on all 3 of my vehicles, they are professional & complete jobs on time, I highly recommend them, Robert Hammond

I could write a book to tell you about the amazing service I received at All Flow, but I’ll keep it short and sweet.
I recently picked up a barn find ’72 F100. I had the truck tuned up and running and in pretty good shape. It had been sitting for years. The main headache (literally) were really bad exhaust leaks on both manifolds. This is a pretty common problem for this model. The bolts were seized on the heads and I had nothing in my DIY garage that could break them loose. I first took the truck to a muffler shop in Vallejo that had a pretty amazing reputation once upon a time. They took the truck in and sat on it for SIX WEEKS. No phone call, no wrench turning… Nothing! To make matters worse, their in shop mechanic tried to poach the job. Shady!
In a panic, I called All Flow and was put at ease by Danny immediately. He advised to get it out of that shop FAST and bring it down to him. I had the truck at his door the following Monday. Shoulda brought it here first. Ah well.
Communication with Danny and Jeff was always great. They would give updates of where they were in the project and a ballpark of completion time. There were a couple of parts snafu’s (thanks Summit) but the truck came out looking, sounding and most importantly, running beautifully.
I ended up getting the heads machined, custom dual exhaust (beautiful welds) with glass packs coming off of Hooker headers. Since the engine was already taken apart, it was decided to upgrade the carb and intake. A new Edelbrock intake and Holley carb did the trick. The fabricated kickdowns Jeff made look better than the stock stuff and the response time is instant.
Don’t let my hot rod story detour you. These guys were rebuilding engines on newer model Hondas and Subarus when I would pop in. I think they do bikes and boats, too. They are truly a full service shop.
I can’t give All Flow a high enough recommendation. I will return again. Thanks guys!

It isn’t very often that one finds a good fit.
But I did, when I needed what I thought was an exhaust leak in my pickup.
I searched for a muffler shop and the only one listed as a muffler shop was All Flow.
Well they turned out to be a muffler shop and so much more.
After inspecting my truck for an exhaust leak it was determined that the problem was most likely a defective freeze plug dripping onto an exhaust pipe and the resulting fumes leaking into the cab of my truck.
So, now. Can they replace the freeze plug?
Yes, and the leaking power steering pump too. And the broken exhaust bracket that they found with the initial inspection.
Am I satisfied? Yes, and then some.
I got my truck back in one day, and I’m writing this review. The first one ever for Unilocal.
I almost forgot to thank Danny and his very able mechanic Jeff.
I’ll be back.

Oh cannot say enough good things about Danny and his crew. We took my truck to Meineke twice and were told that our alternator was fine even though the battery kept going dead for no reason. Called Danny and he was closed but said to bring the truck in anyway. Went out to jump start the truck and someone had literally cut the brand new battery that had died out of our truck. We didn’t even have terminals! I called Danny and told him «never mind». He jumped in his truck and came and put a make shift battery on and hauled out to his shop. Called me Monday to say that it was indeed the alternator. Gave me a price and I told him I’d discuss with my bf and let him know. BF kept forgetting to call him. I finally called back Thursday night and told him to repair it but we can’t pay in full until next week. Danny said not to worry. He let me pick up my newly fixed truck today. We gave him half of the total and will pay the remaining next week. What great service and a wonderful guy. We will definitely be back!

I needed to get a catalytic converter replaced. I was in and out, no hassles and it didn’t break my pocket. These guys are great, I highly recommend their service!

pricy.

Went in to get a muffler done. Only took 45 minutes to do and they charged $ 250 for the labor and the new 80 series muffler. These guys are around the same price as many other shops but the quality of work is incomparable. Remember people, car work isn’t cheap!!! You get good prices like here, or u get a overpriced shop The guy who worked on my car was very nice and knowledgeable. They back their work and products 100%. I enjoyed my experience and will definitely be coming back. Strongly recommend. The small shops are the best ;)

every 3000 miles I bring my van in for a oil change. Thank you again for the fabulous service and always checking things to make sure they are up to par. :)
