Zero stars. Worse place ever! Tore up my car and now my check engine light is on and they didn't fix anything and wastes 3 hours of my time

This shop is nothing but a high-end good quality work muffler shop. These guys have accomplished what no other muffler shop has ever done done for my vehicles. They did an awesome beautiful work of art. On my Tacoma they did exactly what I asked them to do. Exactly how I pictured it in my head same goes for my Infinity. They are very precise on what they do and how they do it and it shows owner was very kind and even worked with me on the price. Definitely going back to this shop for any other future jobs I have! Five star rating definitely recommended read more

Took their time completing the resonator removal. Sound was very good too. Got to work as soon as possible very good service.

Took my car here for a new catalytic converter. I've asked them to take a pic of old and newly installed catalytic converter when finished. They said yes they will provide that. Never provided. Instead they called me to say "your car is ready for pick up, but there's good and bad news. Good news, new catalytic was installed and car passed smog. Bad news, someone hit your car." What they meant was a tech took my car for a test drive and rear ended someone else with MY CAR AND TOTALED MY CAR. But then again, was told my car was fine, just a minor scratch. Til I saw my car, air bag deployed. Yet, they were still fully paid for a product that I never touched, used or seen again. But hey, no big deal is what I was told by the owner of this shop and according to the him, I should be happy and excited I'm gonna get a new car after wrecking my car. He couldn't even provide me a copy of the accident number card from the highway patrol coz "he doesn't have a copy machine at his shop." So, yes, if you never want to see or drive your car again, take it to this shop! He will make sure you will be taken care of! Apparently this shop owner is a very well known business owner by the Bureau of Automotive Repair as well! Good job Hi-Tech Muffler! read more

Went in for an exhaust install, they left it rattling and broke one of my hangers after coming back they refused to repair it. They have decent prices but you get what you pay for. read more

I was told 560 installed. When I got there they said that I needed 2 cats to be sure that the vehicle was fixed properly. I told them that I would come back because I only have money for one. I told them that I would rather come back when I have money for 2 cats. Then they tried to convince me that I needed only one cat. I told them that I would like my car back. I would like to fix my car the right way but not here. read more

Extremely pleased with their services. Great Prices, every other shop I called gave me some ridiculous estimate, not this one. Ask for Alex, he is very knowledgeable and helpful. Will definitely be back in the future. read more

I came in because my car couldn't pass smog. I was told it needed a new catalytic converter. I went with my mother and stepdad. Jorge is pretty straightforward when it comes to talking so I understand why people see him as rude. For example, when my stepdad asked about the price he had written, Jorge said "Hello? You can't read it?" Other than that, the service went great. It was fast, he called me a couple hours later, the check engine light went away, and my car passed smog the next day. read more

The service is trash!! Took my car there the other to get a quote to have some headers installed guy came outside looked and said it'll start at $500 plus $75 for each bolt that breaks because this is a old car, I'm like how would I know that if I am not present to see for myself, not to mention I just had a new intake, manifold and carburetor installed about two weeks prior and not one bolt broke. I laughed it off like yeah ok, his like I can give you a call when I have space to fit you in but he didn't call, I believe they didn't have the competence to perform the work I went straight to Lodi and got it done for $200 read more

Audi Q7 4m: a common issue with these gen Q7's with the 3.0t is the muffler (flex pipe) begins to fail at any random mileage and the only solution per Audi is to replace 2 mufflers (min 1k job). If you have any drone or vibrations at low rpms this is the issue. Alex was awesome, he knew exactly what we needed done to fix the issue. He was able to get me in and out and replaced both flex pipes. That low rpm vibration is now gone! If you need someone to work on the following Audi tsb go see Alex! Thanks again I should note, I went to another muffler shop (high ratings) and he literally said he didn't want to work on my Audi. https://static.nhtsa.gov/odi/tsbs/2019/MC-10161604-0001.pdf read more

I had gotten my catalytic converter stollen last year and needed a replacement, I had gone to hi-tech and was charged $1600 for the replacement and labor. In which I was fine with, However, when trying to do my smog this year I was told that the (hi-tech) converter they had placed was the completely wrong one and was unable to pass smog. Came into the shop (hi tech) to see what was going on along with my paper works and receipt that I still had but was told "We're under new management". Gave the front desk person all my paper work and was told to pull my car up front. After having came back in after pulling my car forward. The documentation and receipt was written on, BUT he insisted that it was there the whole time however the print of the receipt was faded and the new information was just then added freshly. Not willing to help he insisted it was my father and I fault for not following what was written. When clearly he just wrote the information when I was pulling the car up. I would not have done business with them if I knew how scandalous they were. Lesson learned. Would not recommend or come back to this place. read more

My catalytic converter was stolen and I called around for a few quotes. I decided to call Hi-tech muffler due to the mostly good reviews. I called and spoke to Jorge. I got quoted $800 for a new catalytic converter. I asked a few questions regarding my situation. When I asked if that was the total price, or would it cost more depending on the conditions of how it was cut. He said with attitude, " I don't know the condition of it , so bring it to the shop"! I replied yes and ended the conversation. No shit you don't know the conditions of it, but to be straight rude! Common, Jorge should be more professional and patience. This place sucks! Go somewhere else! read more

The new guy that welded on my aftermarket resonator that I brought in... sucks! I did a cold start the next day and saw built up water (from the steam in the exhaust) coming out from the welds. I've been bringing in my cars over the years because they have "Best prices guaranteed" and great welds... the new worker has poor welds and the they asked for $130 to weld on a resonator I brought in when the old owner would've asked for $40-60 to put it on. Disappointed. I have to find a new shop to go to now... read more

First of all the way the owner answers the phone is rude! Although he did get my car done in a timely manner he did not do a very good job! After getting my car back I had to take my car to another shop because there were engine lights on and all it was was a fuse that he should've took care of when he had my car. read more

I purchased a new Mercedes Benz S63 AMG and really wanted to make it louder. I've seen lots of AMG's and they sound amazing with sone modifications to the exhaust and wanted to do the same with mine. Called a few shops in town and nobody knew what to do. Lastly called Hi-tech muffler and Alejandro answered and was very informative and friendly. Got me scheduled in the same day and got me in and out. Very professional and honest shop. Showed me what I needed done and explained everything before they continued to work on it. Thank you hi-tech for getting exactly what I was looking for! Highly recommend them! They did a muffler delete and custom X pipe and resonator delete. Love the way it turned out! read more

Hi-Tech Muffler - S63 and E63 after exhaust done - Auto Repair Near Me - Stockton, California

I had taken my 1951 Chevy Styleline Deluxe to this shop to have a new exhaust put on it. I went with 1 1/4 straight pipe and I have to say the sound it puts out is real nice. I was going to put glass packs but I decided the old school needed straight pipes. I don't regret coming here or my decision on the straight pipes. Be prepared to drop the car off. read more

Don't let the comments about his response for calls sway you, he does honest work at an incredibly fair price. I had him replace a catalytic converter for me and he went out of his way to source and order one at a fraction of the cost as compared to other mechanics in the valley. read more

Thank you Alex for working with my insurance to get my catalytic converter replaced! They were able to send pictures to my insurance for me and I got my car fixed within 24 hours. read more

I gave them 2 stars because the welder is decent and the prices are not bad. The old man who I believe is the owner is a real bitter douche bag. He is very disrespectful and treats you like crap. He gets very upset if you want to pay with a debit or credit card and insults you by saying " I can't believe you don't carry cash" like wtf is it your business if I don't want to carry cash. I would not recommend this place at all. read more

My car is lowered and I mean LOWERED. They were very caring for the car and me as a customer. I had blast pipes that I wanted welded and they asked me a lot of questions to make sure I was satisfied. They gave me a great price as well. Would def go back again if need so. read more

Alex is a very patient and helpful dude. I recommend this shop, they seem honest. They didn't think charging me for a quick inspection was right, so they didn't. I'll be going back for any for any future exhaust modifications. read more
