Had an exhaust leak on my drivers side collector. Got me in and fixed no issue. Recommend for all your exhaust needs!

Mando is rude and not friendly at all. I told him about my issues with my car and he couldn't tell me the price of the car after he looks at it. I was telling him my issues with it and he cuts me off mid sentence and just ignores me and tell me to put my car in the auto shop so he can put it up the car lift to look under the car. Mind you, I have more to tell him and he didn't care. Before he even helped me, he was helping this other dude and I drove 20 mins away and the least he can do is tell me on the phone that his place is cash only. After I finally told him all of my issues with my car, I asked if he took Apple Pay or debit/credit card. He said no, I'm only take cash and I said oh okay well I don't have cash and he says well go across the street to the 7/11 to get cash and I said okay will do. I will be right back and he looked at me like I was so stupid. I left and didn't come back to that auto place. TO ALL THE WOMEN AND GIRLS, PLEASE DO NOT COME HERE ALONE OR AT ALL. He made me feel very uncomfortable when I was telling him about my car and everything. Mando's demeanor is very rude, aggressive and obviously doesn't listen. He is a very mean old man. This auto shop, inside and outside is shady too. It is in a random industrial area. It is a small industrial garage and there is no office to walk into when you get to the place. It's like you walk into someone's garage and it is very dirty inside, trash all over the place too and it's disgusting. Don't come here, it is a waste of time. 0/5 stars!! DO NOT COME HERE. I don't even give it a 1 star. It is a 0/5 stars. read more

Had two exhaust tips replaced, The work was sub standard and expensive. Crooked and uneven both sides. Also asked to have a muffler hole repaired, and was told the hole needed to be there for the water to drain out. I do not recommend this place. read more

Mando did what he said he was. New piping, clean, actually pretty fast for what's involved. Pricing was not bad at all. Actually came in cheaper than like 4 other shops I looked into. I will tell you this, the welds were as clean as you are gonna get. Gotta take my son's care over soon. read more

went in to see if they could replace one of my catalytic converters, Mando was very rude and dismissive. I asked a few questions because I do not know much about cars and he got upset saying I already explained myself that's the price and proceeded to walk away. Would not recommend this place what so ever. Also he scanned my car and proceeded to tell me no codes came up, took it somewhere else and codes came up first try. read more

Charged me 300 to put a cat in and I said I only had 250 at the moment, he said it was fine he would do it for 250, but to bring the 50$ later, well come to find out the next day he left a welded spot purposely without welding so went and told him the cat wasn't welded all the way through, and he said where's my 50$ you owe me, I was like wtf you serious, idk about yall but that's playing dirty, I had his 50$ to give it to him but him leaving it on purpose like that is messed up specially when dealing with new cats and trying to pass smog idk i don't like dealing with snakes like that. read more

Did excellent Job on Fixing the Muffler to my Chevy Traverse and he is open on the First Fay of New Year Good Job Mando.

Mando did an amazing job on my Chevy Tahoe. He showed me the issue with my muffler and recommended me one that was similar to what I was looking to install. I am very happy with his recommendation. He did an amazing job installing as well. He told me that I'd get more flow, which will help me save more gas, and have more power in my car if I decide to put the pedal to the medal. I highly recommend going to his shop for muffler work. P.S he is also knowledgeable about boxing. He is the "Mexican Monster" of muffler installation. Keep up the great work! read more

I just called this shop and asked how much to do a muffler delete (single exhaust) he told me $250.00 and then he asked me how much I want to pay to have it done lol. If this is a business he should know his exact price. That's why he don't have a lot of reviews . read more

Had an issue with my Camaro's exhaust and needed some work done. So glad I found this gem of a spot, Mando and his crew are awesome and let me watch as they worked on my car.

Haven't ever been to a shop where they did that. If you're looking for a place that offers honest, transparent business and competitive prices, hit up Mando's. read more

I've been going to Mando for years on my exhaust/muffler repairs and what can I say he's a great guy and very knowledgeable!

I was really hesitant about doing it myself.. and was actually thinking about doing it myself but in the end I'm glad I came to Mando's for help. He did a great job and the price wasn't too bad. read more

Mando is the man!! I spoke to him the day before I came in to the shop he gave me a great price and stuck to it! It looked like he was leaving for the day when I pulled up he stoped in his tracks open the shop back up got me in and out quicker than any other place I've ever been to!! As I was pulling out he had me stop saw that my headlights lenses were fogged up pulled out a buffing compound buffed my headlights for me!! Great work... amazing craftsmanship if you're looking for a muffler shop this is the place to go to keep it local Spring Valley! read more

Highley recommend Mandos Muffler. Did my Cats and muffler and I couldnt be more happy. Nice guy felt like family. Great price and no bs. Thank you Mando read more

Quality work, friendly service, even allowed me to bring work after hours. And price was beyond reasonable for welds on my motorcycle header. No referral, just found on yelp. read more

Took my 2003 mr2 here to get my entire exhaust system rerouted after I installed a new header that did not mate to my pre-existing downpipe and muffler. I also had him redo the way my muffler tailpipes exit out of my bumper. I wasnt as prepared with the necessary materials when I came over but Mando was able to work his magic, find some things around in the shop and basically created a whole new exhaust set up for me from scratch. There was alot of bending, cutting and welding. He probably spent a good 5-6hrs working on it including our taco lunch but it was definitely worth it. I am completely satisfied with the job he did with what we had and have no complaints! Very awesome hard working guy! Please see this guy with your muffler needs :) I will have to come back sometime for him to do my exhaust tips :) read more

Was a bit nervous getting a muffler and resonator delete since it typically sounds horrible on my car but mando managed to make it sound amazing and I know it's not just me thinking it's good because others have told me that it sounds better than most catbacks people get on my car! read more

I went here to have my grand Cherokee install an exhaust tip I bought online I wanted it welded so it doesn't fall. Mando suggested if I want the resonator out so it would sound better, when he told me how much he's gonna do it for... in a split second I said yesss. His son was also there, a bunch of good people, super easy to talk to and very friendly. A few minutes later everything was done. I will go here again for future exhaust system needs. Thanks Mando and son! read more

Over priced ! Went here to get my exhaust stud replaced and this guy try to charge me 100$ just to replace one stud . After I said "that's way over priced" he said "then we're gonna have problems" . He also said that I made the other customer leave because he was working on my stud . Like wtf I was there first and I'm paying him, that's not my problem that the other customer left . read more

Mando has worked on my Toyota Supra and Nissan 370z and I couldnt be more happy and content with the work he has done on my cars, with the reasonable and affordable prices his quality of work and pricing cannot be beat. I definitely recommend going to him and I will forsure go again when I need work! read more

I got a catback exhaust install with Mando at a great price!! Mando knows what's he's doing and is not trying to rip you off or get rich off of you. I called a few shops in Chula Vista and Spring Valley and got quotes of $200 and up! Really for a bolt of exhaust is kind of high. Mando was nice and installed it fast. If you call him on the weekend and he's available he will install it for you. He did it for me on a Sunday! Great place! read more

Solid Work at a good price! What more can you ask for?! Went to a few places to get quoted for a muffler delete got quoted around 280+ which personally I think is kinda outrageous just to cut off the muffler, add a pipe and weld the tips on. Mando offered to do it for a little more than half! He's a great dude and you can tell he's had plenty of experience, making sure I get the fitment I wanted for the exhaust. If your hesitant to go, I'd definitely recommend that you should. read more

Mando's was recommended to me by some friends that have gone through him. I went in looking to get some work on my car done and I was met with a short wait and superb service.

Was looking for a muffler delete and a y pipe for my Ralliart, everyone else had quoted around 400 and up, and with that price I might as well just buy a Borla and install it myself. Came in pretty late, around 7pm on a Friday and he took a look at my car and gave me the best price in town for what I wanted. He got started right away and took him less than an hour to complete and finish. I fell in love with the new sound my baby is making! Will definitely recommend this place to everyone! read more
