World Mufflers

Patrick is absolutely fantastic. I went to get my exhaust adjusted and he was very knowledgeable and helpful giving me tips and his honest opinion on what should be done. He is very precise and thorough, double and triple making sure everything line up equally both sides. He also does alignment at his shop too, but I didn't get that done. I appreciate that he takes the time to make sure everything line up correctly and that it is positioned to my liking.
I would 100% return for alignment or any exhaust needs.

Pat is awesome, honest and to the point. The welds look amazing and the price he gave me was fair. I came in midweek in person to get a quote because he needed to see the bottom of my car first. He then gave me a price and wedge me in his schedule, on a saturday too when he was already booked which i really appreciate. After a few hours he called me to tell me to come see it. He left it on the lift to show me and explained a few things. But great work i highly reccomend him for any exhaust work. He even gave me reccomendations on what to do if i wanted it louder. Thank you Pat :)

Customer service 5/5

I have a 2015 Prius and (now) live in a highish theft area for...catalytic converters. I personally know 2 people who've had their catalytic converters removed for them (unwillingly). I researched 'catalytic converter shields' on Amazon and came upon some options. That said, I decided to find a shop to install it, as I did not think having thousands of lbs of metal above me made a lot of practical sense. I received a couple quotes and decided to call shops directly. Pat, the owner of World Mufflers, gave me a detailed explanation and ordered the part directly for me from Amazon (I have a C, which seems to be rare? and did not find the matching item on Amazon). We scheduled an appointment, Pat took me in early and got done faster than expected.

Definitely going back if I need a new cat (crossing fingers never), muffler, or another shield. Thanks Pat!

Honest, no nonsense and to the point. I thought I needed new catalytic converters for my 300ZX Twin-Turbo, and called Pat to replace them. Pat said why do you think you need them? I didn't need them. He could have easily just sold me what I asked for. That was 2 years ago. Now I might need catalytic converters and will consult Pat. Recently I had the after market exhaust replaced with stock exhaust for a very fair price on my Z.

I highly recommend this shop for muffler/exhaust related work.

Pat has been helping us with our vehicles' exhaust and alignment needs for years! Always gives us a fair price, great service, and easy to deal with!

Great shop! Been there for a few time for muffler replacement and wheel alignment. Had great experience each time. Patrick (the owner) is very knowledge in his field, and most importantly he's extremely efficient, he gets thing done, done right, and done within the time he said he would. He explains things clearly, on point, while he doesn't waste his and your time, he's very patient to explain when you ask clear and specific questions.

And his prices are awesome for the services he offers. Pay him a visit if you have the need for exhaust work or your periodic alignments, the 5-star reviews are very true about Patrick and his business. This is the kind of local shop still showcasing true integrity and outstanding work ethic.

Owner did a nice job and fixed my exaust pipe along with a resonator Delete at a reasonable price and was quick with it.....:) :)

Great service from Pat. Was looking for Millercat Shield for our Gen2 Prius. When we called in the morning, he said that his appointments for the day were booked but he could try and work us in by the end of the day if we could drop the car off before 10am. Dropped the car off before 9am and got a call from Pat at 11:30am - that the car was ready to be picked. He even gave us pictures of his work and took sometime to explained about the extra security measure he did to deter a theft.

We know that the shield is a deterrent but since our other Gen2 Prius just had it's CAT stolen we want to get some protection. We will have Pat install a new CAT on our Prius that was a victim of a theft and also install another Millercat Shield.

Pat squeezed me in on his busy schedule and got a pipe parallel (J-pipe) to my exhaust to reduce drone noise. The welds looks nice and neat. Compared weld works to a few others in the Bay and World Mufflers tops them and reasonably priced. Well worth the drive down from SF

Make sure to make an appointment if you need any exhaust or alignment done

Pat is the man. He's an absolute professional at his craft and could teach a master class in exhaust work, welding and alignments.

Pat has done a plethora of exhaust and alignment work on my two BMWs. The muffler delete on my BMW E90 330i was impeccable. Pat did a great job with cutting off the OEM muffler, welding on the new straight pipe and aligning the exhaust tip with the diffuser. My BMW G30 540i xDrive also has had a center resonator delete and a full axle-back exhaust installed. Absolutely love the sound and the quality of the workmanship from Pat. Lastly, he's performed a few custom alignments on my not-so-stock 540i xDrive (it has F90 M5 full suspension retrofitted). Not only that, but he also accommodated re-doing one of the alignments since I was noticing some rubbing and visual differences in the rear negative camber.

Overall, Pat is a good dude and I won't be taking my cars anywhere else in the Bay Area for exhaust work or alignments!
