Simon & Gee Muffler/Auto Body

Called in the morning and brought my car in a couple of hours later. Mr. Gee was super friendly, showed me where my cat converter was and showed me that he was replacing it with the correct part per automaker’s book. I was in and out of there in less than 30 min. And my car finally passed the smog check (3^rd time’s a charm…). Thank you Mr. Gee! :)

I went here thrice for my exhaust jobs not for the quality but the inexpensive part of it.
well every time i went there the guy wasn’t courteous at all but i didnt care because
it was a straight deal.
but yesterday i wanted to change my muffler and he said no… thats too complicated
constantly nodding head (very annoying) looks like i was trying to get it done for free.
that was very disappointing «in this day when every customer counts and is imp to the business» thats how to handle a business.
i was immediately going to walk away but all the muffler shops around were busy and i had to replace the old rotten muffler.
hence i stayed back.
and then during the whole repairing part he dropped the «F» word million times
cursing my muffler set up and cutting the tubes in the wrong angle.
may be this shop gets 5 stars for it being cheap in repairs and all but lets not forget
this isnt some place like xyz country where people dont care about each other while at business.
this is America where compassion and hospitality has given birth in daily business life.
have a good one guys.
next time you go there make that guy smile or something…
oh wait he cant see bcoz he’d be wearing those welding shades even when he isnt. and nor can he listen because hes constantly listening to music on his head phones even while at work (definitely not safe) or off work.

Great work, great service!
I was in and out in 30 minutes! Simon and Gee is fast and reliable. My muffler had started to fall off over the weekend, I called my normal mechanic doesn’t to mufflers but recommended Simon and Gee, I’m so glad he did! I pulled in Monday morning and they helped me right away — even showed me what would need to be repaired and offered to do it in 30 minutes at a fraction of the price i was expecting!
I recommend these guys for any work needed!

Nissan Dealer told me I needed new muffler & center pipe for 2005 Nissan Altima. Estimate was $ 1300. Co-​worker recommended Simon & Gee. Called them up, Gee said bring it in. Didn’t have to wait at all. Gee (I thought it was «G») who is very personable put the car on the lift, inspected my slightly crimped muffler and gave an estimate of $ 50. An hour later I came back, the muffler/​center pipe was repaired. True to his estimate the final charge was only $ 50, plus sales tax I think. These guys are obviously honest and more than fair.

You can’t beat these guys in speed, customer service and price. Come here and you won’t be disappointed. In and out in less than 30 min for a complete exhaust. Bring your car here if you want to save time and money!

Ever have one of those days where you’re backing out a space in the company parking lot and your tail pipe just hits the curb when the curb jumps out to hit your tail pipe? Bad curb. Curb your curb. It was actually rather humorous. I do a 240 versus a 360 to get out of the space and my tail pipe just exactly hit to where it broke the exhaust pipe and I was about to leave the tail pipe extension and the part of the tail pipe that broke off in an effort to vamoose out of embarrassment — but when I stopped a few yards away to take a look, I was shocked to find the tail pipe and extension were missing … MIA … so I went back and picked them up. Let’s see, Lexus dealership would likely go to town on this one. Call Karl as I recall he had a Lexus repair department friend. Karl restores vintage cars and he suggested I go to Simon and Gee instead. «They can just weld it back and you’ll never have to worry about it again. Just drive up and they can do it on the spot. Cost you $ 20.»
Well it was $ 40 but as you can likely tell from the other reviews, it would likely cost a lot more elsewhere, you probably wouldn’t get drive in/​drive out service and these good people obviously know what they are doing so beside mufflers and automotive restorations, if you need a good welder, now you know where to go.

Absolutely awesome. Went there after my car sounded asthmatic and wheezing badly. Simon found the leak in the header and let me know what was going to happen. He cut and re-​welded and had my car purring in less than an hour on a saturday! Excellent, cheap, and fast are a really hard to comeby combination, but simon and gee deliver!

This review is for auto body repair!
Thank goodness for Simon & Gee!
My dad was actually the one who brought my car in for an estimate (after a pretty bad side swept my car took — back fender and back door so badly crushed in to the point where the door could not even open, front door dented all along the side and minor scratches in the back bumper and front fender) and let me start by saying that their asking price was SIGNIFICANTLY less than all the other estimates I received from other body shops from around the city.
I was a little skeptical about the low price so I immediately searched them up on Unilocal before making a decision. I learned that they had all 5 star ratings, but only 12 reviews that mainly focuses on catalytic converters whereas my car was in need of body repair… however, I decided to take my chances and left my baby in their hands.
Now, I do not know who exactly worked on my car but I just got it back today and it looks, feels and smells brand spanking NEW. I cannot be happier, my little civic is gorgeous again! I am so amazed with the great job they did! They really hit the home run with detailing, new layer of wax, and how the back fender — originally crushed in and cannot be replaced, only pulled back out to it’s initial position — is so smooth and looks as if nothing ever happened! They even washed & detailed my car & did something to all 4 of my tires to make them look shiny and new! In addition to that, my car was ready 3 days earlier than the original estimated finish date, they just keep getting better.
Kudos to you Simon & Gee. I am so glad I left my car with you guys. I’ll be recommending all my friends to you if they need anything to be done on their cars. Thanks again for the great body work!

So I got my catalytic converter stolen from my early model Toyota Tacoma. I researched other places in SF but I decided on this muffler shop to handle it. These people are not sketchy at all and very quick and professional. Simon gave me a grand tour of what happened (my cat was unbolted, cut from the muffler, and the oxygen sensor was stolen with it). It was very nice of him to spend 10 minutes explaining the whole process to me and we determined my truck needed a OBDII complaint catcon with a rear O2 sensor.
Gee jacked up the truck and welded it together in a few minutes. My OEM cat was replaced with a generic one (cheaper and less of a theft target). My truck sounded like a monster truck going in and purred on the way out. All in all, the repair took 30 minutes.
I did require a new oxygen sensor, so instead of charging me more or holding my truck while it was ordered, Simon simply referred me to a shop where I could find one and screw it into the rear of my exhaust myself.
The next day I heard a little rattle, so I called Simon. I was in the next day and Gee again jacked up my truck, fixed the welding, and I was up and running FREE of charge. Gee just loves to weld away so it was like I did him a favor.
My grand total for an OBD-​II catcon with install was only $ 290. However, this does not include an oxygen sensor that I still have to pick up.
So, if your catcon is stolen:
1. Go here to get it replaced.
2. Get a generic catalytic converter (lasts a few years and won’t get stolen). If you have a pre-​95 car (some exceptions) you will get a cheaper OBD-​I catcon. If it is newer than 1995, you will get an OBD-​II catcon.
3. Have them match an O2 sensor with it and install it while it was jacked up.
4. ask to have it WELDED on so that it is not unbolted and stolen again.
5. Have Gee literally BANG on the system for any rattles. I know it sounds ghetto, but it works! Also, drive it around the block to make sure there is no other noise.
6. Make sure your «check engine» light is off.

These dudes are great, Fixed up my gfs car after I run into a muni bus and installed a new exhaust on my truck. All quick and easy and CHEAP!

This auto body shop is AWSOME, CHEAP, and GREAT & FAST SERVICE. nowhere else can beat the price here forsure. My car needed to change the brake, i brought it in when they were closing at 1pm on saturday and it was ready to pick up on monday morning (they close on sunday). so there, fast service. Min Wu, the manager there is really helpful. he told me what need to replace and gave me a price (quote). i had asked around, and he gave me the cheapest price compare to other shops. I highlt recommand this auto shop if your car need any service :)

I was seaching on Unilocal to find a place to change my catalytic converter on my 97 eclipse! So I saw the review was not bad so I bring my car there! It only take them less than 30 min to change it and the service was wonderful and friendly! The price was not what I expected, I thought is going to be expensive but it was not. It was only $ 250 out of door! Highly recommend!!!

You can’t beat this place for the money. I took my 53 Desoto in to have it’s old single holey exhaust removed and replaced with duals and dump tubes. Gee worked with me to get everything just right. I provided the Smithy mufflers and SS Dumps and he did the rest for a cool $ 340. If you’ve got an old car and need an exhaust done, I wouldn’t hesitate to talk to these guys.

I have never written a review on Unilocal (though I use it all the time), but I just got home from Simon and Gee a few minutes ago, and writing this review is the first thing I am doing!
I needed a new muffler (my car was LOUD), and Richardson’s Automotive referred me to these guys. When I drove in, the clock on my car stereo read 8:57am. The 2 guys were incredibly friendly, and drove my car up onto the blocks immediately.
When I left my car stereo clock read 9:14am. It only took SEVENTEEN MINUTES!
A new muffler with labor cost me only $ 67 and change. (I have a ’97 Jeep Cherokee.)
This was by far the best car-​fixing experience of my life. I would recommend these guy a million times over.

When i lived in LA i bought and sold mid-60’s model Mustangs and 70’s model Jeeps (CJ5’s and CJ7’s). I’d pick them up all over California (mainly in Humboldt county) and truck them back to LA. Of course i had to do work on some of them, and had a stable of mechanics i trusted who i used regularly (my fav were friends who charged me a 12 pack of whatever the cheapest beer i could find to do afternoon repairs).
When i moved to SF i continued buying and selling cars and motorcycles to pay my way through college. the scene in the bay area was nowhere near as robust, but during my sales i needed a couple good mechanics. the best i found was at Golden Auto, and the managers name was Simon. I took all of my vehicles there (mine or those for sale), and Simon was always honest and fair.
One day i went back to Golden and was told Simon was gone (as was Gee who did all the exhaust work), and ownership had transferred. I tried them once, and pricing had changed dramatically. I asked where Simon went. one of the mechanics was good enough to tell me he and Gee had opened a muffler shop a few blocks away on Harrison.
I dropped by and said hi to Simon. Over the past 10 years i’ve had him work on the few cars i’ve had over that period including friends who needed exhaust work.
Here are the examples of his pricing on my last few cars:
Mercedes Catalytic Converter:
Dealer/​OEM — $ 800+
Simon/​Gee — $ 160
Nissan 4×4 dual exhaust:
Muffler Shop — $ 600
Simon/​Gee — $ 210
BMW Z3 Catalytic Converter:
Dealer/​OEM — $ 1800
Simon/​Gee — $ 175
Swear to God!!!

As a newcomer to SF, found myself with a broken and noisy muffler and no good knowledge of the local shops. Pointed to Simon and Gee, my faith in craftsmanship and the basic decency of mankind was restored. In a no-​nonsense, efficient and transparent operation, the job was done quickly at such a reasonable price, that this ranked among the best value-​for-​money experiences ever … and how often does one feel that way after coming out of a auto repair shop you dont know when you have an existing problem???

I ended up here this morning after a random hole corroded it’s way through my exhaust connector pipe, making my car sounds like two harleys riding in tandem. They looked at the part with me and replaced the pipe –it took a half hour, if that, and only set me back $ 50. Place looks pretty basic, but they do good work. Recommended by Cowden Auto, which is the best auto repair shop ever. Ladies– they won’t rip you off, or assume you’re an idiot. That fact alone is worth 5 stars.

They did a wonderful paint job on my bumper! And it took them two days, which, I think, is pretty quick. Anyway, the shop might not look so nice and fancy, but it’s a body shop, what do you expect? We mainly dealt with Sunny, and he was very helpful (you can go ahead and ask for him). Only $ 350 (cash) for the whole deal, and they washed my car for me too. Great service!
