Had a new catalytic converter installed by them, guaranteed I'd pass my smog, turns out months later I get a check engine light error code saying the converter is faulty, called them and they refused to help, just get it done somewhere else. Don't trust this place read more

The BEST muffler shop in all of LA. If you need ANY modification, install, or exhaust questions, come to these guys at KING MUFFLER! They know what they are doing and have been here since 1988.

There's a lot of shops in the valley and LA to choose from, but their reputation speaks for itself. 5/5 stars for me read more

This guy saved me big time on my muffler, I didn't think it was my muffler but he diagnosed the exact problem in 10 seconds lol. He then cut out the problem, welded a new pipe and my muffler STOPPED making that horrible noise. Fast easy and very reasonably priced. Now I can enjoy my drive read more

Harry did amazing, precise work adjusting a cat back exhaust when I wasn't satisfied with another shop's installation. Came back to have a muffler installed on a truck and a resonator delete on another vehicle. Everything was perfect. I've recommended several friends who also had good experiences. Harry is super friendly, experienced, and has the knowledge/skill to do quality work on any type of vehicle. Highly recommended. read more

Yup, phenomenally honest. I asked about a catalytic converter replacement, as I had a warning light on at some point and that's the code that came up. But it was either Harry or Sam who told me that's the last thing you should do. Car is running fine? Yeah it's perfect, I said. They said don't do anything you don't need to do. Super honest. Thank you. read more

I came to repair a hole in my exhaust system and left with new accessories. Quality work and great customer service. Will definitely come back for future mods. read more

Harry was great. Just picked up my car. Within a few hours of dropping it off, he replaced the 2 catalytic converters and the muffler on my 2011 Nissan Versa. It drives quietly and smoothly, like it used to. The Nissan dealership wanted to charge $3K, he did it all for $1350, and much faster than they would have. read more

There some jackasses in the world don't take it there save your self the grief read more

this is the muffler shop you should go if you need exhaust work done right. price is also reasonable

took my car here the other day because i dint like how it was sounding my boys over at king look at my exhaust pipes and suggested a flow master swap. let me tell you that once i was back on the road my car sounds a lot more aggressive and much faster!! the price wasn't that bad for the part and labor they also notice i was missing some bolts in the headers. thanks again guys !!! highly recommended read more

If I could do 10 Stars I would. The Range Rover dealership told me I had a crack in the exhaust manifold and the price they gave was outrageous. I went by King Muffler to see what they could do and he put it up on the lift, inspected everything thoroughly and told me there was no crack in the exhaust manifold and no problems that he could see... he said if a warning light came on you would be glad to recheck it but until then it needs nothing. When asked him how much the inspection was he told me there was no charge and if I need something in the future they'd be glad to take care of me. This is the way it should be. I'm a doctor and if a patient comes in that really doesn't need to see me, I make sure they get a referral to a doctor that can help them and I don't charge them. We're all here to get through everything together. Many thanks to King Muffler read more

Came in to have my truck fitted with a new muffler. Guys there were helpful and asked how much I wanted to pay after I got a quote from someone else. He agreed to my price and said he'd get it done. I recommend getting there early in the morning if you want to get your stuff done. First time I tried getting there they were slammed and I knew it would be a long wait. read more

Had a downpipe installed by a local independent shop and it was leaking and sounded terrible. I brought in with no appt and they took the car right back and found the source of the leak. The previous shop had used clamps and king muffler suggested we weld it in place. While it was on the lift I asked about removing the resonator and they gave me a fair price. They were all done within 30 minutes. If you have any muffler or exhaust related work go check them out. read more

I guess it's time for me to write a review. I'm a regular customer at this shop, I've been to this place probably 5 or 6 times, not because they did something wrong to my car, just because I'm experimenting with my exhaust and King muffler is the only place I like to go to. They work with you. If you don't know what you want they can help you, they can order any exhaust that you need from the warehouse same day. Never felt that I was overcharged, always reasonable price. Am I recommending this place?! Absolutely!!! read more

My guy always does an amazing job, you want a good quality job and a good price go here

First time writing a review mostly doing this as proof since you can't leave any voice mails on their number. Had them install an exhaust today on my Alfa Romeo Guilia on Saturday (March 18) left the car on Friday. At the time didn't think to check for any issues since I trusted them and was in a rush but my mistake. After taking a good look around the car once getting home noticed they damaged the car in different areas. Will be in contact with them on Monday to see how they will solve this. read more

King Muffler was amazing. Harry was so accommodating to my circumstances. I was having such a difficult time with my smog check given that my catalytic converter was stolen in November 2020 during a period of illness. Harry was very accommodating located the best part for my car which he did his research and found the correct catalytic converter that could be installed on my Honda. Note it was the correct approved part in the state of California. Unfortunately the DMV did not think so and I had to jump through hoops just to get my car approved for a smog check. First, I went to a state of California BAR referee. Which I didn't even know existed but apparently what their job is basically to inspect aftermarket parts that were installed on your vehicle which in this case it was a catalytic converter. My first appointment with this referee did not go so well he declined the part that was installed at muffler King and the referee informed me that I needed a brand new catalytic converter. I called Harry at muffler King and heroes more than accommodating and fair with prices to the Catalytic converter that was listed on a new list that the referee provided during the first appointment. Come to find out, that referee was incorrect and Harry really did put the correct part on my car. During the process Harry was very accommodating and supportive. He did not charge me after seeing my car and expecting it multiple times. The shop was understanding and it was working with me during this process. After two months I am glad to post that my car was approved by this referee and my Muffler is now registered in the state of California. Which I didn't know was a thing but I guess we all have to register or catalytic converter's thank you state of California that's where my taxpayer money is going to. Thank you to muffler King , Harry and the staff that works at the shop. I would definitely recommend the shop for anyone that would be interested in replacing a stolen catalytic converter which has been happening a lot in the San Fernando Valley. Get a job you losers stop stealing catalytic converter's you guys are some real POS! read more

Highly recommend this place if you need a service they provide. Wanted a part installed on my car that they didn't have in stock. They were able to same day it to their shop and have it installed by the night. Harry helped us out along the way and was great with communicating along the way. Definitely worth reaching out to if you need something read more
