Laguna Muffler Service

Amazing shop, this is the only muffler shop in OC that seems to do an absolutely perfect job. All my friends and I regularly swap out mufflers and resonators and run straight pipes of car shows and auto cross events and here we never have to worry about bad welds are cheap materials. The prices are great and the quality of work is even better. This is the only shop I would ever trust to touch my cars. Can’t recommend this place enough, will be back in later this week.

Old school shop that is reliable and friendly. You never feel pressured into repairs that aren’t needed.
Thank you guys

I have been coming here for decades, but on occasion seek competitive bids from other area muffler shops. If I’ve learned anything in my life it’s that Laguna Muffler charges far less than the competition; often as much as 2/​3rds less! But this facility is not all glitter: the showroom resembles an unattended Motel 6 from the 60’s and if the acrid smoke and sparks from welding upsets you then perhaps you should wait outside or take a stroll. These two fellows, I’ll call them «the sage» and «the whippersnapper» have never accomplished anything less than a professional job, and I can truthfully report they appreciate a good joke, PC or not. And if you «flip some cabbage» on them, you might even get a better discount.

Called magnaflow and they pointed me in the right direction on what muffler would work well. Then told me to check out Laguna Muffler. I am beyond pleased. Frank sr, talked with me, asked me what I wanted and delivered! I put a magnaflow 12 289 on a Chevy Silverado 5.3L and asked Frank to custom it to dump in front of the rear tire. No frills cost and I walked away knowing I wasn’t taken advantage of. I recommend them 100%.

If you need to have a catalytic convertor installed i recommend finding a different shop.
My experience with this shop has cost me a lot of money after failing my smog test after this shop did not make proper complete welds around the entire outer diameter of the new cats that they installed. This allowed oxygen to be drawn through the poorly welded spots and this caused the NOX readings to go sky high! This also flagged my vehicle as a GROSS POLLUTER which has caused me problems ever since.
When i returned to this shop to have them make it right i was greeted by a grumpy welder that offered no apologies for the lack of quality nor the extra costs i incurred for the lack of professionalism that this shop exudes.
AVOID THIS SHOP!!!

My cat converter was stolen about 4 years ago. Laguna muffler replaced it, and I’ve had problems passing smog ever since… I should’ve returned to them when I first had the problem, but I didnt. And i just called to see if they could give me an idea of how long ago I replaced it and how long they warranty their cats for AND an estimate of a new one… (CAUSE I WAS GOING TO USE THEM AGAIN WHY???) but guy on the phone couldn’t give me even a ball park estimate for just LOOKING at my truck… he just said «we have competitive prices but ok» and hung up on me… I’m confused, but I guess they don’t want old business asking questions? From my mechanics understanding it was a cheap cat converter installed in my truck, they dont last like they should and that’s why I have this reoccurring problem.

Laguna Mufflers is great. I had been avoiding replacing my rusted muffler because I dreaded what it would cost. But I needed to get it smogged and it had to have a new muffler. I went there without an appointment and was out of there an out later with a new muffler and pipes for only $ 150. Great people, great service. A good old Mom and Pop shop that will do a great job for you.

I give them 5 stars for their honesty, excellent skills, fast service, and very affordable prices. I arrived at this place looking to replace the exhaust pipe and possibly the muffler as well on a Jeep, as recommended by another shop. Not knowing what I was getting into, no appointment, just pulled up and within minutes they gave me the cheapest estimate. It tuns out that I didn’t need to replace anything since it wasn’t that bad. They went ahead and did a quick welding job and $ 30 later I was very satisfied with the job.
I definitely recommend this shop for all your exhaust system repair requirements.

STOP!!! Please for the love of your car and your investment please do not take it to Laguna Muffler. I took my track FR-​S in to get a headerback exhaust hooked up and the younger guy, maybe his son started working on disconnecting the cat from the front pipe.
I was sitting rite there rite in front of him and the whole time he’s swearing under his breath but clearly loud enough because he was frusterated at a bolt not coming off. I mean he was cranking this thing like no tomorrow. NO RESPECT for other people’s vehicles. He let some guy start wrenching trying to get the bolt off… Some random guy that brough his car in too I guess they were buddies.
So after these knuckleheads wrench their heart’s away on my car they cause so much fricton on the plastic underframe they stripped a 1.7inch hole in the plastic. It might be just plastic, and may just be under the car… But its not your car to put holes it, that’s not what I’m there for. But you know what, that’s NOT EVEN THE BIGGSST ISSUE!
He quit, just quit and said it won’t come off. So yes he stripped the bolt that connects the cat to over pipe. So I asked him is everything bolted back and OK to drive since he quit and said he couldn’t do it. Was everything ok? Nope. TWO MINUTES DOWN THE ROAD MY CAR BLOWS SMOKE THROUGH THE VENT AND I SEE SMOKE COMING OUT OF THE HOOD.
This idiot (the older man frank was nice and professional bit he was with his buddy customer and his worker/​son was working on my car) not only quit, but let me drive away knowing that the gasket didn’t have a proper seal, and that the bolt is stripped and isnt giving an air tight seal. I have NO power from 2−4k RPM I know something’s wrong. So now I’m at the Toyota dealership getting everything looked at and documented since this is absolutely the WORST and most UNPROFESSIONAL experience ever.
On a side not too for anyone who cares enough to have read this far. This guy even tried raising his voice and getting closer to my face when I explained to him that bolts dont just come stripped and I’m going to take it to a dealer to look over it. He said, get this, Toyota uses cheap nuts and bolts and cheap parts and this is common for bolts to strip. On brand new 2013 model cars? I don’t think so. I wouldnt write this much if I didn’t care.
If the owner reads this, please work with this individual and show him the professionalism and quality work that has had your shop surviving this long. I promise you this employee is going to be the end of your business. He doesn’t want to work there he doesn’t like the work he does. I hope you read this Frank, I really do. You sound like a devoted and honest man but your employee is going to bring you down if these issues aren’t addressed. Thank you.
Update (@3:27PM-01/03/2013): I just got back from the dealership. The worker had «mutilated» the catalytic converter hanger bolt threading and left the cat connected by one good bolt on tight and one stripped bolted on loose which caused the gas leak into the cabin and smoke under the hood. Total cost of repair was $ 75 dollars. Also the part mentioned earlier (plastic rear splash guard) was quoted $ 140. I will be taking action in getting full reimbursement. I will keep Unilocalers updated.

I took my 2011 C300 to LM and they did an outstanding job on putting a Xpipe on it. I am so happy and the service was great and the price was the best of all. Thanks Frank you guys ROCK! I recommend anyone to go here for small/​large and custom jobs. These guys have over 35 years experience and know what they are doing!!.
They also worked on my 2008 VM Golf GTI and had the same experience.

Went there on recommendation of my independent Jaguar shop… Great Job great prices !!! Mom and pop operation and I love it. Father and son duo, is just the way I like it hahahaha

Fast, friendly service. No bells and whistles in the waiting area but who cares about that when you just want them to focus on your car

Excellent. They did an excellent job installing a catalytic converter on my car. The dealer had quoted me just under two grand, so I pulled out my iPhone, typed in muffler service, and called this place. They wanted about four hundred. They did a great job, and they were very friendly and nice. I highly recommend this place based on my experience. I remember driving by this place for at least the past twenty years. The lady inside said they’ve been there 33 years now. Five Stars all the way.
Update: I just passed my smog check on the first try !

What can I say that’s positive about my experience here… nada.
It was recommended by someone that had their exhaust rerouted there, but I should have looked at the work up close.
Firstly, the son was in a crappy-​a– mood and even complained about «hating to do these kind of jobs» while my truck was on the rack.
Then after I left, not only did I notice a whistling sound that only got worse as I recognized it as gaps in the welds (2 different spots), but the muffler body was hanging well below the frame rails and just asking to get ripped off.
So I call to complain and say I only what the owner to touch my truck, and he closes the gaps and raises the body. Seemed all good ’til I took it out to the desert and he welded the rubber bracket to the frame instead of bolting it, so there’s no adjustment. Basically it stretched the rubber hole and the exhaust tip rattles like a Vegas slot machine!
DON’T GO HERE, go to DVP Auto/​Exhaust!
