It's not a muffler shop anymore. It's a private diesel truck company that take cares of its own trucks

Very quick service. Knowledgeable and friendly. The tech took one look and knew exactly what needed to be repaired.

Adrian installed new headers for a great price on my BRZ. Definitely recommend. Really nice guy!

Was my first time here and Adrian guide me through the types of mufflers they had and what each did. We began with a delete and it sounded well but as the week went by I didn't like it after all so I came back the next week and Adrian got me right and installed a 40 series Flowmaster on my 2024 jeep Grand Cherokee and man did it make a difference. read more

Lou's muffler was very pleasant experience and he saved me hundreds of dollars by just welding my muffler rather than replacing it. Another repair shop tried to charge me over $500.00 for a new muffler but I wanted a second opinion from a reputable muffler shop. Will definitely be going back for any muffler repair or replacements. read more

Adrian was friendly and professional. He did a great job welding my stock OEM muffler on my Mini Cooper. I cut off the muffler because the Mini exhaust is one piece from the downpipe back. I did this to make it easier to store. I was running an aftermarket exhaust system and decided to put the stock exhaust back on. I highly recommend this muffler shop. read more

See all

Happy with experience Needed a new muffler on my '96 Toyota T100. Adrian was very friendly. he quoted me $160 for a universal muffler, in stock, parts and labor, one year guarantee. I asked him if i brought the muffler specific to my model. he said $120 labor and no guarantee. I went with his in stock muffler. 2 months later she is running great. on a saturday, dropped off at 9am, was ready by noon. read more

An hour before closing, Lou's Muffler Shop told my daughter they would be happy to take a look at her car. Within minutes of her arrival, she had a dx of the problem that was not only explained but showed to her, was told the part she needed was on hand, given a very fair quote on the repair and was told her car would be ready in 45 minutes. She left Lou's relieved, confident in the quality of work and happy with the price she paid... we definitely recommend Lou's Muffler Shop! read more

Lou's Muffler Shop - Getting my catalytic converters put back on after it was stolen a few weeks ago...Thanks to Lou's Muffler Shop... - Auto Repair Near Me - Pico Rivera, California

Stop looking for any muffler shop, this is the right place, the right price and the right service. I bring my 6 year old Xterra here, and I knew my cat converter was bad (since that is what I read on my computer after I check the SES ligth) so lift the truck and the first thing Larry told me was that my truck was on warranty so I should take my truck to the dealership and get the job for free. I was an ignorant, I didn't know that emissions on any vehicle had 7 years 80.000 miles warranty, and this guy didn't take advantage of my ignorance, instead he actually helped me, even he tried to connect me with the right place. This is the kind of people that make you thank God for found them in your path. I tried to pay him.. and he refuse to take any payment.. Literally I was shock. Totally recommended shop. read more

I take all my exhaust needs to Larry. Pleasure to deal with, never disappoints. This time had to move the tailpipe an inch to accommodate install of an anti sway bar. read more

Make sure before you call you know everything there is to know about your car or else why call a specialist to help. Smh. Called another shop. what a great guy. Told me how to find the info and actually helped. Going to spend my money there. read more

Recently took my truck In there and was fairly impressed with the work but not the business. The mechanic/welder there Bryan was very helpful in explaining all the work and had some quality welds to go with it. The owner I think Raul I cannot say the same for however, while waiting he was very rude and obnoxious to the point they almost lost my business. He began pitching me on a completely different exhaust setup that made no sense then discussed and tried to change pricing on me when the work was done. It is unfortunate that the original owner Larry and now Raul do not know how to honestly run a business. Would not recommend! read more

Very knowledgeable technician and pricing is very reasonable. Larry, the owner, stands behind his work. You'll be a customer for life once you get your work done here. read more

One of those places where ppl who don't know much about cars go to because it has decent reviews. Checked in since it's local but trust me don't spend your money here. Their work is half assed. They couldn't do a simple job on my car. Ended up going to a shop in East LA to fix their mess. Also the workers don't wear masks if that bothers you. read more

I needed some work done on my Toyota Tacoma (2008) since my CHECK ENGINE LIGHT came on and as it turns out I was in need of a new catalytic converter and O2 sensor. All this has to be done before my SMOG check can be completed which sucks because I waited until the last day to have all this done. Called Lous' on Monday and spoke to Larry, he said to bring in my truck to verify the trucks information and this way he could be able to get me some pricing and availability. To my luck there was an aftermarket available which saved me some money because one from Toyota would cost me north of $1500 plus the sensor $200 and plus the labor. So Larry really took care of me. Larry priced me out and I felt he was fair and he could have it done the same day, which was great considering I got there at almost 12 pm. I won't go into pricing details since not every car is the same and some may require other additional items. Let's just say, Larry called me about 1.5 hours later and said my truck was ready. So excited, good work, quality parts, cleared me codes and little down time. I am very pleased, the facility is clean, plenty of parking, clean waiting room area. Just south of Beverly blvd but north of Olympic blvd in Pico Rivera, very easy to find. So glad I found this place. read more

This place is well worth every cent$$$$$$ I had 40 series installed on my Mustang and it sounds great. I almost doubled paid at another muffler shop.

Great experience. Fair price. Very helpful. My mom was in a pinch, so I took her car here and these guys were awesome. If you have exhaust issues don't think twice, go see Lou!! read more

I came here to install my flowmaster muffler, it had a different off set than my original muffler. The old guy that was working there said he couldn't do it because it was a little different. I told him that all you had to do is put in a new pipe to fit it. He still said it couldn't be done. Stupid really. I guess he didn't want to make that extra effort to do all that work. So I took it somewhere else which was no problem for them to do it. Maybe he's just lazy. Bad rep for the company. read more

Awesome work, honest person and reasonable/realistic prices. My dad and brothers have been going to Lou's Muffler and now it's my turn. Larry, the current owner and son of Lou is great to deal with and tells it like it is. No over-charging, no trying to sell you more than you need. Heck, he even did some welding on some stuff that was non-auto related. Thumbs up to Lou's Muffler Shop and thank you Larry for the great service. read more

Larry is great. He assessed the issue that I had regarding the exhaust pipe and had it finished within ten minutes. (Mind you, I was there on a weekday in the morning). Rate was more than fair. He is very professional and knowledgeable in this trade. I will be returning as a repeat customer. read more

I am so very happy with my experience here. My muffler had become detached from the bottom of my car and was severely damaged. I was terrified that I would not find a place that I could communicate with or afford. This place is on point and will restore your faith in the human race! Honest and caring. Excellent service and affordable rate. I have a new muffler & tailpipe and my car is running better than it has in a very long time! Kudos!! read more

Took my '98 CR-V to Larry at Lou's Muffler Shop and he did a great job on replacing the car's rusted catalytic converter at a very reasonable price. Larry's prices were very competitive compared to other places I contacted. Although I live in OC - I plan on taking our vehicles back here for muffler/exhaust system repairs - no 2nd thoughts about it. Honest mechanic & quality work at reasonable prices - I like Lou's. read more
